what do you all think

this is what i got

30x30x48inch plywood box
all painted flat white
150 watt hps light and 2 flourecents on eacch side
im using bag seeds in roots organics.
3/4 gall square pots
room temp is about 78
my humidity is low du to being in garage and its cold out.
i use ph tap water no ferts yet
2 and a half weeks or so .
seemed the soil is way low on ph. so last week i flushed the crap out of them and this is where im at
well i tested the water that came out at the begining of flush and after and it seemed to help
what does everyone think
what to do??

Does your water have chlorine if so you should let it rest for atleats 24h before using it! if its 2 1\2 weeks old you can start giving the young-ling some veg nutes!
Those lower leaves maybe be from lack of nutes!
If i am wrong please correct me i am no expert in diagnoses!!
Good luck mate

Think posporus def
what else need some criticism

ive got a similar setup but im growing in a mix of MG organic choice and vermiculite.. my leafs got the exact same thing going on..
i figured the MG was over fertilizing so i transplanted into regular soil yesterday, but im interested in a diagnosis for sure..
good luck man

I would replace your 150 with a 250. Best thing i ever did. Why the garage? Worried about smell? I would use distilled water or like david said, let it sit out for 24 hours and then ph it. I would get some exhaust going on in there to and a fan blowing not directly on the plants but toward a wall in there to bank some air around. wind/water/ventilation are all very important.

Dope setup with the floros on the side. Looks like the soil is pretty dry and the leaves are a little droopy. Idk what your water schedule is but don't let it dry all the way out. Get some blue light in there, like a couple cool temp cfl's and it will perk them up in veg too. Good luck mate

Thank you guys for the input
I do plan on getting a fan blowing on the girls
like Sooon
as for exhaust I'm in the north east so it's
sill cold about 30at night so temps are not a problem
will cut in a computer fan when it gets warmer
well I fed the girls some light nutrientmix and let's see if it helps
keeeep sending info

try flushing them with water and back the light off a lot....
same thing happened to me week later all good

do you run the light 24 hrs? if not how cold does it get when they are off? i would get a good ventilation system. this can be as important as the lighting you use.i have that same light i use it for veg and keep it about 6-12 inches with a circulating fan blowing up at it. this keeps the whole reflector cool to the touch. i use a 4 inch inline fan for exhaust. my temps in my veg is 76-78.

I installed a computer fan today to get the air
moving a little more. I am still waiting for the
outside temp to go up a little more before I cut
in a exhaust hole with fan.temps outside at night here
in new England are still in the twentys so I don't
want to suck in to cold of air.I run my lights 24hours
and my temps are 70-75 with the lights now about
16 inches from the plants

As always thanks and let the coments fly..

what water are you using? if it is tap water you should test the ppm. if you dont have a tester, you should be able to get an analysis from your water company. or you can skip that step and use RO water or at the very least run your water through a brita filter or something. it is hard to pin point what might be the exact problem but if you get the basics down (light, water, air) the plants should bounce back. in my experience it is easier to just change everything so it is all dialed in than guessing what your problem is changing one thing at a time. ventilation is not only for heat exhaust and temp control but is essential for giving the plants fresh air with fresh co2.

Thanks I
I leave the door cracked and am in the box twice a day
I agree with you it's more easy to change up everything
but my last try started the same way.
I think I have read just about the whole
site- and have Infomation overload
just got to find what WORKS for me and my girls
I think I have a well enough set up
just have to learn.... The hard way
it's funny that's the only way I learn
