Odd taco curling, help plz first time soil from hyrdo

[Growstaman]

Hello everyone, I am pretty new to this forum but have been reading up on it often, to start out I am using a small apartment closet til I get outta this place.

Current setup:
Stains: Random, was doing this as a test run for sil before I go for the gold
4 26w (100w) CFL (Upping it to 6 very soon if able to vent on time)
1 Hanging fan for circulation
1 Dayton knock off cpu fan bout 112 CFM (Currently just blowing, soon ducting into wall for air out and intake onto rubbermaid for flowering
1 Cheap low cpu cfm fan blowing upward into bulbs as more air circulation
Temp usually 70-78 max, for a day or 2 was in 66-68 for a cold spike we had

3 - 2 Gal soil pots with about 12-14 holes drilled in bottom for draining
-Pots are filled with Roots Organic soil with pearlite added for better drainage, bottom filled with about 1/2 to 1 inch of pearlite on top of newspaper for drainage

-Thus far have mostly only straight ph'd water with 1 run of dolomite sweetener/half dose fox farm grow big for a calcium issue

Side note: Planning to LST after watering tomorrow just for more yield due to limited space

Watering: So far usually fill about 2-3 1 gallon bottles with mix or plain PH'd water I am using, water soil with about 1/2 to 1/3 gallon each til I see sufficient drainage and pot fills like its retaining water (USUALLY lasts about 2-4 days of feed)
Now for the problem:
Problem started occurring after last watering, which at first I was assuming a PH issue cause pen was being a little finickey. Calibrating it again tomorrow with new watering, but for now still am worried with this issue. From what pen read it was a TAD bit low at about a 6.6, usually I water with at least 6.8 to 6.9 resulting in a 6.6-6.8 run off.

SO after this last watering they have definately had a great growth spirt putting out more defined and bigger leaves. Now my one plant that was at first doing great has started curing up quite hard, tacoing even, with a bit of bleachy/yellowing spots near the curling which lead me to believe it was possibly heat.... Moved the CFLS about hand span distance from plant (roughly 5-6 inch atm). Only seems to get hot at night when door is closed, which I have noticed a quick burst of heat in morning, which is why I plan to vent into walls soon.

Though it does seem like maybe heat/underwater I am unable to tell and about to water again tomorrow. Tested soil tonight and it is mostly dried back out with pots being very light again. Tomorrow they will recieve a 6.8-6.9 ph water with full nutes/dolomite

I am just slightly worried as this has not improved over the last couple of days and I am sorta at a loss for what could solve it, any help would be greatly appreciated and I shall provide updates for anything I may have missed while posting all the specs.

This is the one curling, cfl now about 5 inches or so above plant, curling started after last watering, temps been 75 and under





These 2 are doing better with no curling

Yea i'd guess a hot spot. Lower humidity causing leave to fold up, and slight burn.

Hmm that is true, didn't think much about humidity this time around. Low humid will really make it curl like that?

Hi, Dude. I would start by, taking the peat pellets away. Looks like nutrient burn. And how about some 8 gallon grow bags, as your roots, need space to grow. If your root bound, bigger pots, if its nutrient burn, flush with 70 degree water, 3 times the medium ( soil plant is in ). Then, I would re-pot them with no peat pellets in the way ( just use a razor, and cut the skin, off, the pellets -- "MESH" -- . Make sure the lights are not to close, and then, 1 week later, resume feed, at 2/ 3rds, of recommended, suggestion on bottle.


regards mate,
