The tops aren't bad just a few leaves look really bad and it looked like it was getting worse and spreading

Yes I put a little amount (.5tsp/gal) to make up for the deficiency in the RO water. Did I fuck up?

And is 12-24 hours ok to flush for

The flush is to remove as much nutrient solids from the root zone as possible, it's not a feeding process.

Yeah, let them sit in water for a day or so, but not much longer. And remember, the flushing is for flushing, not feeding. Once your plants have been purged in water for a day, give them the reduced nute and calmag mixture I described.

I understand the purpose but I thought since I am using RO water not hard water the upside is no chlorine but the downside is there is no nutrients that hard water has so I thought to put the CaMg+ I bought (same thing as calmag I think). Should I re-flush with just ph water and no camg+ or is it ok that I put it.

The bottle says to put 1 tsp/gal for light feeding and 2tsp/gal for heavy feeding. I only put .5tsp/gal

Ok this might sound ignorant, but here goes. 2 600's for 4 plants? Did you veg for like 2 months? Also, what's the temp in your room with that kind light? Do you have fans running? New air being refreshed into the space? A lot of questions for me. I skimmed thru most of the post, but didn't see anything like that except for nute and pH suggestions. Forgive me if I missed them.

The room is big that is why I have 2 600's. I vegd for a month and a half the temp is high since adding the second 600W its about 82degrees in there which I understand is high but I open the door for it to vent once in a while. I have a little fan in there and a 4inch inline fan running through both lights.

It should be okay. Just let 'em sit for a few hours like that and when you do your second flush, nothing but water.

Yeah mist/foliar feeding plants with the lights on concentrates the light and burns the shit outta the leaves. Wanted to make sure you hadn't.

Where does your light fan vent to? Is it right out into the same room or into another room/outside? I'm guessing you're not using CO2 at all right?

If your not using the Floralicious and the Koolbloom I'd have to say your potassium deficient. Also the Floranoa is notoriousely lacking in calcium and magnesium so you should be adding cal-mag too.

Yeah but unless those 4 plants are big enough to cover 18 square feet of space your gonna be wasten lota light and electricity.

You should see 2 elbos for your work and they would have to be 6 ft each min for that to occur (is that what your doin) if so hang lights vertcaly Iv seen amazing things with that .

They are just hanging horizontally across a ~6.5 x 5.5 walk in closet.

I do not know what you mean by elbows but the plants are pretty tall right now, maybe 5 feet including the bucket I haven't measured them

I did realize I could fit more plants in there so for my next grow I think I will do 6 plants
