Curling and Twisting leaves Please help DIAGNOSE!!

SOIL&POTS: These are plants in MG moisture control soil most in 1 gal growbags 18days in the soil.
LIGHTING: CFL 6500k 100w 1500 lumens x 6 and Floro tubes 6500k 4' 3000 lumens x 2 ..I also have some cfl 200W 4200k lights are they any good heard they were wrong spectrum?!?!
GROW ROOM: 2 1/2' by 5' closet grow
AIR: nice 8" oscillating fan on them.
TEMP&HUMID: 75-80 degrees F./35-50% Humidity depending on weather outside being that is summer and my windows allways open for fresh air. differs from day to night.
WATER: tap water that has sat for atleast 24hr and PH'd to as close as i can get it to 6.0 or 6.5 alkalinity is med along with the cyanauric acid

MY CONCERN: I gave these plants MG all purpose 24-8-16 ferts at 1/4 dose 4 days ago some of them have bounces back but some of them are very droopy and twisted looking i looked at the underside of the leaves and it appears there are little brownish marks on the stem that runs throw the leaf is this from the over ferting burning the water ways or what? will they stop twisting

Ps a brother needs some rep for such a detailed report lol

my leaves were curling and twisting like that and my ph was way out of wack. I flushed with phd water 6.5. What are you testing with

Twisted leaves are a dead indication of pH issues on the low side and the possibility of nute lockout , the MG can be low to begin with and is most times not . You will see an improvement if you raise the pH next watering and maintain it closer to 7 . Might rethink the ferts too as the soil has time released capsules

just with test strips i couldnt find a digital one anywhere wallmart or canadian tire... i live in small town..i wouldnt wanna flush with the MG soil and the fact there only 18 days old there not to established yet.

Also how often are you watering?

my tap water comes out of the tap at about 7.8 should i just water them with straight outta the tap water?

if you can't get a reliable meter get those aquarium ph test kits with a range of 4 to 9 or something and use that they are cheap and you can get them at pet stores or wal-mart. Thats what I have been using and no more problems as far as that goes anyway. You might have to flush to fix the problem man all the nutes from the MG are being locked out any way, I would get that ph kit ph your water closer to 7 like mentioned above and then test the ph of the run off. then you can flush, it won't hurt them.

7.8 is to high!

I would not use 7.8 unless they were really locked out but in your situation 6.8-7.0 would be the safest until they are over this minor issue .

thanks guys!

Ditto to that, most likely your pH levels and nute lockout. Is the water draining easily or is it standing?
