Help Plz! seedling leaves are drying at the tips and curling

[Mammath]

Thanks for more pics.
2'6" sounds good for now, that distance between the 3rd and 2nd node looks a lot better. I always use the back of my hand at plant level to feel the heat from the lamp to judge correct distance.
With the JF's you could have probably had those cfl's a little closer but better to be a little stretched than fried. Just keep an eye on them under the 1000w, if they continue stretching lift them up to get more of the light.
All the best with this grow, I'm watching with great anticipation.

Just wanted to put up a pic of each one of the 3 fem arjans ultra haze...one of them is extra sativa looking and has some crazy nodal growth goin on...I think they are doing well with the recovery from those crazy ppms and whatnot..ppm is at 210 right now..keeping ph from 5.6-6.3....here are some pics of the 5 fem jask flash, they are coming along i nicely i think. Tomorrow the supplies to upgrade our system should be in and I am very excited to get that going...when do you think I should put the JF's into the system? When we do we will be changing out the res solution to accomidate the little ones of course.

oh yea and would i be able to take a pic of the roots hanging out the bottom or is that to much light exposure?

 

[SciensWiz]

another question...do you think i should top these guys? and how would i go about doing that?

Interesting question. Being a sativa, I would, unless you want 12ft plants.
Oh shit, ultra haze, yeah sativa! I haven't asked you why you chose this strain?
Other than the fact it's won so many awards.
You must be a patient kind of person? Or you just love that 'trippy up high?'
Have you checked out the GHSC grow on youtube? Here's a link >>>
Also ,check out who's grown this before, and see if they topped. Research, then decide for yourself.
Indoors, I top everything because that's what suits me, and my set up, best.
Entirely up to you which way you go.
Here's a topping link >>>

 

[SciensWiz]

Yea I am definately topping the ultra hazes..that link there is great for alot of solid information. I chose the ultra haze because of the high thc to cbd ratio and that cerebral high, im pretty down for that...and yea ive watched all the ultra haze videos..in fact i bought the GHSC seeds because the videos solidified my decision...The JK's however, are from sensi seeds.

The guy on that thread says once your plants have 5-6 nodes..cut right above the second true node...Im just thinking thats alot of growth to be taking off. Its really gunna hurt me inside to take all that hard earned growth off to shorten these plants up but its supposed to be worth it..im gunna only do it to one of them tonight because i should be able to see where the new growth points are within about 24 hrs...then ill do the other 2

it will be good to know how this works out before I have to do it to the JF's

this technique is supposed to give them 4 main colas and higher yeild capacity i think

 

[Mammath]

You don't have to let the plant grow to much past where your going to top it. If you want to top after the second true node then you're ready for that. I always top after the 4th true node but it depends on the strain. I think your are ready to top at anytime. Make sure you use some sterilized scissors.
Not only does it produce more tops but it promotes the bottom branches to grow out and up.
The pictures below are my current grow, she was topped after the forth node and is now producing 6 - 10 nice colas. Pictures taken at week 3 12/12.

PS. GHSC have some excellent strains. I have the Himalayan Gold and Big Bang seeds I will be growing in the future. Sensi seeds are also a very reputable seed co' and I have a Super Skunk of theirs which is 4 days old in my veg cab . That will be part of my next grow.

 

[SciensWiz]

yea i just topped the one that was looking the most pure sativa like right above the second node like that look u showd me said...But im thinking about topping right above the 3rd node of the other ones. So are you saying you wait till your plants have 4 nodes and then u top them right above the second node...or that you top them right above the 4th node? your plant is looking very nice there...i can see 9 good colas coming up..that baby is gunna produce..what strain is it? and is that one plant or two, how big is your container

Wait until they have 4 nodes and top above the 4th.
or wait until they have 3 nodes and top above the 3rd.
No need to grow the plant above where your going to top.
All you need is enough growth so you can see where to cut.
My plant is just some bagseed I'm flowering to test out my new flower cabinet I've made. I think it's going to work pretty good. Looking forward to getting some quality strains into it. I've just sprouted a Sensi Super Skunk and a Flying Dutchmen Nepal Kush in my veg cabinet, they'll be ready to go straight in when she's done. I'm trying to create a 6-8week turn around.
It is just one plant. The pot it's in is a 30L I think. I can fit 2 of them in there. Some would say it's overkill for the size I grow them out but I like to give the roots plenty of space, they grow so fast when unrestricted, plus I'm in coco-coir.

 

[SciensWiz]

yea i just toped one right above the 2nd node and the other 2 right above the 3rd node...It will be interesting to see how they differ..it sucks though cuzz i lost over a week of growth...they just look lame as hell right now...this is my first grow though so i guess i dont know any better....my dad was a bot major and got me growing stuff from a really early age but i never really messed with any of the details..

when i was in highschool i was growing 18 bagseed plants on my roof...my older brother told on me and this is my first grow since then...they were actually really healthy good looking plants over a foot tall each...ive always wanted to grow some pot...its like the ultimate thing to grow and perfect imo...just wanna do things right the first time around and not fuck anything up to bad..

tomorrow im upgrading the system so it recirculates and ill be puting the other 5 pots onto the system for the JF's...You can see the roots on the bottom of the little rockwool cubes starting to come out...are they ready for the system? I know...I never run out of questions to ask..

 

[Mammath]

Yeah, get the JF's in there. They don't need any more than 150ppm at the moment though.

 

[SciensWiz]

just upgraded the system to recirculate and the ph's are still different at every bucket...this is so damn frustrating...shoulda spent the extra dough to get an ebb&flow...ill let ya know if i figure this mess out..ill take some pics tomorrow

OK. What nutes are you using?
Your using quite a 'complicated' set up now. Not really, but for your experience you are pushing it a bit. I'm sure I mentioned earlier in the thread that recirculating will only make shit more difficult. Keep it simple.
Anyway. What nutes are you using?

So I got back from class today and all the buckets including the control bucket are all reading the same pH's either 6.2 or 6.3...a little high but thats about as high as ill let them get normally...yesterday after getting it all together it was a little wack...hopefuly it stays consistant. Maybe it just needed to circulate a few times and even out.

Anyways yea I think I mentioned it before, Im using Advanced Nutrients. If you go to the website discountadvancednutrients.com you can check it out. I used the DAN's Timeline tab(its a chart) on the website to help me figure out what I wanted to get, I aslo used the nutrient calculator(at the very bottom left of the homepage) to help me out with mixing...Im using the sensi 2 part as my base fertilizer. If you plug sensi 2 part in the calculator and plug in rooted clones/seedlings into the formula it shows what you should be using during that stage of growth and what ppm u should be around. I lowered the dossage/ppms for the JF's. Where it says what I should be using for my growth stage im using everything but tarantula and piranha. Im using lower dosage ratios than it suggests to keep my ppms down. I thought these would be the best nutrients to get, I did alot of research and watched alot of youtube videos on the different products they have and everything sounded good..but of course I have no first hand expirience with ferts so I made my decision with what looked/sounded the best.

 

[Mammath]

Cool. I hope that PH stays consistent for you.
I guess with a name like 'SciensWiz' you don't mind a bit of a challenge?
Sorting out a water farm for a first grow is definitely a challenge but I guess if you take a scientific approach you've got a good chance of getting right.
I personally think you need to be a scientist to run one of those things.
It's even more complicated with those various nutes you using but you probably enjoy that.
I was thinking that the PH imbalance is partly or mostly nute related, like 'old pothead' suggested earlier in the thread. I was going to suggest a simpler nute solution but if your starting to get it right with what you have lets see how it goes.
When using such a blend of additives and 2 part mixes it doesn't take much to upset that sort of system, less variables the better for achieving consistency.
How are the plants looking over all? Are they greening up? What's your current PPM?
How are the roots looking? Some say it's best to have a bubbler for every tub, more O2 the better. What do you think?
Get some pics up over the weekend if you can, I'm keen to take a gander.

 

[SciensWiz]

lol hell yea the plants are all looking good and yes they are all greening up...before I topped the 3 arjans the secondary nodal growth was pretty yellow and not getting much light because of the fan leaves blocking im guessing but they are growing like mad and almost the same tone green as the first pair of old fan leaves. I think the lighting is at a good distance because not even the JF's have made any vertical growth, their leaves are getting bigger and their second true leaves are starting to look good(theyre probably putting alot towards root growth as well). Yea youre probably right on about the nut combination, combining all that stuff for sure does some wierd things to the PH. Yea science besides art was always my favorite subject and even before I knew about pot the biology of plants always really fascinated me. This system with these nutes really do make for a chore but I enjoy it as long as I only have to readjust the control res to keep things steady. I am for sure up for the challenge, I was definately over my head in the beginning but I think im starting to understand how everything tics. Yea I have had airstones in all the individual buckets for a while now and I know thats working wonders(ill put up a pic for proof). I also had CO2 running to each individual plant but I had to take it down when I put in the JF's for the final arrangment, ill be reconfiguring that later tonight. I think the JF's are gunna have a much better start than the arjans because in the beginning we didnt have humidifiers to keep the RH right and you know we fucked up on the ppm in the beginning on those.

Anyways here are some pics of how things are going..Dont mind those old nute burned leaves on the arjans...the one in the back was topped at the second node will the 2 in the front were topped at the 3rd..

Look at that bagseed taking off..for sure an indica..any guess at what it is? it did come from a sack of marginal dro..

 

[Mammath]

Yeah shit, they're looking at lot better.
Topping really encourages them to bush out and you'll get a lot more colas.
What ppm you on at the moment?
They're maybe able to take a little more now.(350-400). The JF don't need that much though.

 

[SciensWiz]

hmm 6 of the pics didnt come up...here they are..

 

[SciensWiz]

The ppm is at 140 right now because of the jacks...I know the arjans can handle more..but no worries Im giving it a VHO foliar spray and a Revive foliar spray during the dark cycle( check those 2 advanced nutrients products out..good stuff and its working)...because theyre all connected ive gota wait till the jacks catch up a bit..everything is greener than it looks..my camera makes everything look brighter..

 

[Mammath]

Roots look great, very healthy.
So what's the current ppm. I think they could do with an increase depending on what it currently is.
Those JF's are going to be the shit!

lol i just said the ppm is at 140 because of the JF's...but im giving the 3 arjans foliar sprays to make up for it

yea im hopping the JF's are a smooth ride all the way through..including the smoke
