Looks like overwatering to me.

I never water them when they are still wet, the ones in the pic look really wet as I had just flushed them with a clearing solution before the pics.

I was given the nutrient chart by my buddy, he swears he uses it, were both doing same strain (PK). Ive been having problems with mites, i asked a couple people and they suggested adding the SM90 with my food, which is why ive been doing it. I will cut back on the nutrients and follow the GH chart, also will lower my co2 ppm to 1000, and I will be adding a intake and exhaust for the lights off period tomorrow. Thanks for all the help guys, I will post some more pics in a couple days and let you know if things are looking better.

Purple Kush in 5g pots with promix hp.

Just flipped to flower 7 days ago, on day 4 leaves began to curl a bit. Also noticed some leaves are starting to yellow while the veins stay green. Any help narrowing down the deficiency as I believe a few nute deficiencys will cause the yellowing. The curling took place pretty soon after putting it into flower, where I have a co2 burner. Could my co2 level be too high and causing the leaf curl and deficiency??

Also, when the lights are off, my burner isnt running, but the co2 level raises to 1900ppm from the plants. I have no intake or exhaust to exchange the room with fresh air, its not a 100% sealed room, but I have nothing drawing air in, is this a problem?

PH 6.3
water temp 68
co2 burner set to 1500ppm (is this too high for week 1 flower)

Nutes: (per gallon)
Week 1
GH Micro 8ml
GH Grow 6ml
GH Bloom 8ml
SM90 3ml
Diamond Nectar 15ml

You said the water temp, but what is the temp around the plants?? Leaves curling like that can sometimes be simply from heat.

I have it set to 73 degrees, the temperature around the plants fluctuates a little bit when the ac is on/off

So its been 3 days of lowered co2 ppm (set it to 900), and one day of having the room vented for 30 minutes 3 times a night when the lights are off. 90% of the curling of the leaves is gone, so I am happy with that! The 3 plants that are showing the yellow/white leaves still arent showing improvements, so I will turn my attention to them now. I flushed them with clearing solution 2 days ago. Today I decided to check the run off as I suspect its a PH issue.
I gave them 5 litres of ph 6.5 water, then collected the run off and ph tested it, and it came back as ph 6.1. Am i correct that this means my soil ph is somewhere around 5.8? which is too low? I tested the run off of one of my healthy plants and the run off tested 6.5 which I think is proper soil ph. How should I raise the 3 sick plants soil ph, should I flush it with ph 7.0 water, or should I flush it with half dose of nutrients adjusted to 7.0, or what would be best?

forgot to add, I also am following the GH feeding chart now, which is ALOT less nutes then what i was previously using.
