Getting Worried!!

[madness]

Hey all, I'm not sure what to think or what to do. I'm getting worried. I need some ideas please.


Setup as it stands:

Seedlings

PH: 6.5
PPM: 540
Temp: 79
Soil: Organic hydroponic medium (Coco Fiber, perlite, etc)
Water: Cristal Natural Spring Water
Nutes: Grow 6-4-3
Light: 600w sodium
Light Period: 24hrs
Over all time: day 25

How close is that 600w light? Might be to much for the little one. Why you using spring water?

 

[fried at 420]

yea def the result of too much light move it and that should cure the problem and dont use spring water has low ph level use regular tap its wayyy better

give me a hell yeah

At day 25 the light shouldnt be an issue. Shows definate Nitrogen deficiency. What kind of Nitrogen/nutes are you feeding it? The coco fiber and the ph can be the cause here this is basically close to a hydro type grow so the ph should be around 5.5-5.8. Dont use the spring water tap water is fine just ph it.79 might be a bhit high unless you have good fans moving the air since your not using co2 try for 75ish. Dont overwater either as the coco holds water. You may need to flush as the high ph may have created lock out then start a good nitrogen feed on this.

Looks like a potassium / magnesium deficiency. That bottled water is more than likely reverse osmosis. R/O lacks pot. / mag. Keep using r/o and add 1tsp./gal of epsom salt when watering. or use cal/mag supplements.

I don't think it is the lights to close. Would'nt the tops show the probs?

I'm not sure what the ph should be for coco. Ph can always be adjusted even if spring water.

Good Luck,
DH

Follow Fletch's advice and your plant will come back. If you light was burning the plants the evidence of light burn would be on the top of the plant, not the bottom.

Using spring water because don't have RO.

 

[FilthyFletch]

I dont see any signs of potassoium or mag deficiency not sure what your seeing but the colors of the plant show nitrogen deficiency most likely from lock out from the coco and ph

Hey all, well as far as the water, I do adjust the spring water ph to 6.5. But I think I might move to tap. I was just talking to a fellow farmer and he mentioned that because of my every 3-4 day watering with nuts, i might need to just water with fresh water to kinda flush a possible build up. What are your thoughts on that? He thinks that because of the curling tips and brown fringes. I am waiting to get the PH pen to have the right read on the soil ph. I know what is going in but not sure what it is in the soil itself. As far as the light, it's about 8 inches and has a flow hood and heat is being drawn out.

Here is another question. You think that perhaps the bottled spring water is missing elements like Iron and other minerals that exist in tap? And, do you guys always use tap?

Thnks

Yip 2nd fletch and bras here. Straight hydro mix with coco, using spring/RO water and you're probably only feeding a straight NPK nute right? Definite signs of mag/cal deficiency, pretty far into.
Get some calmag in there or another feed with mixed micro nutes. Not too much light.
Good luck.

Hello Trichomekid,

Yeah I am feeding straight NPK, but I also just heard that I should not feed at every watering because the soil can have to much nute buildup. Is that so? And should I switch to tap to get more minerals in there? Of course setting the PH to ±6.5.

thanks

Yep feeding everytime causes build up in the soil and then problems. Have you tested the ph of your tap water?
Tap does have some macro stuff that is beneficial to the plants. It also has chlorine, so let it set out at least a day before you use it. luck

Stated using Spring water right off the bat. I will test the tap's PH. Is 6.5 a good ph setting? I'm thinking it might be a bit of nute burn because of my feeding habit. I was thinking feeding nute every other feed, does that sound right to do?

Thanks

every other feed is still a lot, just go with wHatever the back of the box says....mine are like half foot tall and i feed every 10 days at half strenth

6.5 ph allows the plant's easy uptake of all vital nutrients. You know a good flush never hurts anything, especially if the is strong suspicion of over feeding. Overfeeding can also keep the soil ph all locked up or fluctuating contsantly, the runnoff could have a different ph than soil in these circumstances. Also since they have been fed and fed more there could be saltz build up, which the plants have big issues with. I reccomend a big flush and then let your soil get dry (3-4 days after a flush) then just plain ph'd water another watering or 2. Then start back on 1/2 dose of nutrients. hope this helps

ok cool that makes sense especially because they are in soil. Thank you

Thanks I did my first flush last night. Like you said it can't hurt. Thanks for the info!

Well it all depends on what nutes you are feeding and also even more importantly WHAT THEY NEED. If you're using chemical nutes then every couple of weeks are normally good. I have always prefered organic based nutes though as they don't build up toxicity nearly as easily as the synthetic counterparts, so they are a lot easier to use (more forgiving) than stright chemical nutes which is better for the novice grower. This also means you won't need to flush like everyone says, even before harvest! There are so many benifits to organics I can carry on info here.. I would first test your tap water for the tds and ph before using it. Depends on where you live, some tap water could kill a plant in days, other flourish.
Good luck

Hello trichomeKid,

Well, I am using organic nutes. As far as tapwater, I live in Puerto Viejo Costa Rica and I am not sure if it is good. Everything they seem to do in this country is less than mediocre. I doubt the water would be any different. But well I have been using water machine Spring water which I'm sure is missing elements such as iron, cal, and other beneficial stuff that tap normally has in the states. I have 10gl of it that I aerating as we speak and will give it a try on some test plants.
On that note. I want to rid the tap of chlorine/chloramine/ammonia. I used to be an aquariest and used a water conditioner (de-chlorifier) for making tank water. It didn't kill the fish, I wonder if it would be as good for the plants. Know anthing about that? Anyways, plants are looking better. I've been foilage feeding N,P,K, and a low dose of nutes. Leaves are starting to green up again.
So by the way, thanks for all the info. How long you've been at this? It's my first with lots of reading but little practice.

Thanks
