2x2x5 Grow Lab - Reserva Privada Headband ... [ 100w T5 veg / 250w HPS flower ]

and while I love hitting oil, i just caught on to dry ice hash. it looks so easy and effortless. I might just make a lot of that stuff. concentrates for the win!

Agreed. Whole new levels with that stuff.

How much of a yeild do you think you'll get out of that?

Wondering the complete same thing, as I have my gl60 just waiting to be outfitted, but i'm following verde and seeing it i can replicate his grow... wondering how much fruit he getting out of this all.

Calling on subscribers! Need some advice..

Pretty much the entire foliage of the top canopy is at risk... I'm not sure if it's serious nutrient burn, or heat damage from the HPS. From what I'm seeing I'm thinking heat damage? But IDK I seek advice..



Some background:

I haven't checked on them in a while, and realized that it had been 6 days since I watered them.. I usually do 4 or 5.. When I checked I noticed the whole top foliage was burned to hell... And the dehumidifier was off.

The previous two waterings were fresh water.. clean with only 5mL of CalMag added... I made sure to water them through really nice to wash out some of the nutes in the soil... Or so I thought? They weren't burned like this two weeks ago, and I've been watering with plain water ever since. Now I'm noticing that the lower leaves look completely fine, and the upper leaves look really bad... The flowers are OK but the burn is spreading to the little leaves on the flowers....



messed up leaves




I've since backed the light off like 2 inches, and I shut down the CFLs on the side. The temps used to be 78-80F on the canopy with the HPS @ 9inches, now they are like 76F with the HPS @ 11inches.

Here is the lower foliage.. All looks healthy??


I'm not worried about the foliage affected so far, I just want the issue solved so the flowers dont get affected... I expected the big foliage to yellow out and die anyway within the next month, but I dont want the flowers all burned up
This is my first time using these FF nutes, and a new strain so there are too many variables for me to nail this down without help..

Thanks folks! I appreciate you taking the time to save these meds..

PS: I have a good thing to report.... The smell has totally changed into some crazy complex, lemony-kushy smell, instead of the very diesel smell... Very headstash.

is it hot in there? perhaps its a deficiency + heat and dryness, not a burn

I didn't think it was particularly hot... 78-80... But that was just the canopy, and I'm not sure about radiant heat from the bulb.. Plus I had the 65w underneath the canopy.. It's 74.5F now at night though with the CFL off and the light raised a bit..


Do you think the dryness could attribute to the leaves burning up? Combined with the heat?

I kind of always thought that the leaves would withstand the dry periods for more than a week but maybe not in those conditions?


Leaf damage is always tough because it's difficult to tell if its getting worse or balancing out...

Hey verde do you know if the Botanicare Liquid Karma is like your Kelp Fert ?

Wow great grow, this is so useful for me! I am just starting a 2 plant headband scrog in a grow lab, so your grow is the perfect guide! The only difference is that i am using a GL80 (2.5 by 2.5) with a 400 watt MH/HPS. Anyways, I had to dig up my ROI account just so i could comment, havnt been on here in a while! Is it allowed to post links to other forums? im keeping my grow journal on GC and if you have a account on there id love if you could jump in! Heres the link: http://forum.grasscity.com/indoor-grow-journals/991650-first-grow-707-headband-clones-400-watt-mh-hps-scrog.html

And some pics I took today:


I have a few questions in particular:

Looking back, how long would you veg and flower? How about if you had been using 400 watts in a GL80? Is there anything else you would do differently knowing what you know now?

Sorry for bombarding you with questions, Im just so stoked to have found this thread and got so excited while reading through it and seeing it go so well for you. Id really appreciate some input on my grow as it is my first one and you seem to really know your shit!

Hey Verde my Ladyburn had a leaf issue similar to yours. I'm also running a gl60 but with twin 250's I never figured out the cause but still pulled 8 zips off the plant. Link in sig has pics.

if its continueous like that maybe its a long out. ... maybe flush . ? but i forgot your medium tho so am prolly wrong

sorry i corrected wrong . ment lock out . ... and continuous

thats what I was going to say but he's been flushing for some time now. thats why I suggested a deficiency.


maybe they're just getting there, you know? like when the leaves die off and the trichs ripen up. its a good thing. maybe its happening

not necessarily a 'good' thing in the sense of the plant loves it, but you know what I mean?

Feel free to PM me if you want.. I'd probably veg until they start filling up some of the screen then switch... I think mine only stretched 2.5x-3x if that helps.. I wouldn't do much different besides feed less .

Thats strange... Maybe it is radiant heat if your in the same tent as me with more heat.

Does nute lock out deficiency start showing from the top down? I don't remember

My medium is Fox Farms Ocean Forest with Perlite mixed in.. I'm using fox farms nutes..

Yeah I thought about that for a second too but the little leaves on the flowers are starting to get burned too... Usually only the nutes get sucked out of the fan leaves and the fan leaves die off... This is pretty much all foliage on the top...




Ive had the CFL off and the temp is at 74F at the canopy... 5F lower than it was before.... lets hope these girls brush off this burn and start growing green again.. Lets hope it was the heat in the last week just building up.




Well, we are on day 43 flower now...

I watered them on day 42 with some food.. I was leaning towards deficiency, + heat.. So i gave them a moderate bloom feed with low Cal Mag..

Fed on day 42 with /gal

20mL big bloom
15mL Tiger Bloom
2mL Cal Mag

pH balanced to 6.6

Nice grow sr. Verde, how much are you expecting to yield out of your tent? I plan to get a 600 watt light and a 4x4 tent, if I grow in a party cup sog how much do you think I could yield I was thinking that if people can get an o a plant I can be safe to say I will have maybe 7 grams a cup and I can fit 144 in a 4x4 space, idk do you think that it is possible?

id just do 4 big plants scrog

idk about my yield

Do you think that would yield more then a whole bunch of party cups?

can't say ive never done it

umm not really sure just looking at the leaves..uhh.. make sure you water bit prior to turning out light or with lights off and then of course bit before..not really good to water plants in light and leave the water on them because the water droplets that are formed on the surface of the leaves and the petals act as miniature lenses and focus the sun rays on the tissue ; thus scorching them, and disfiguring them .looks like those are bad burns and not just yellowing that would form..

Lol, don't listen to that^

If that were true, consider what would happen in nature if there was rain and the sun were out............
