leaves yellowing and curling down

well i have a 650 watt light and well ph 6.5 temp 72 thr 80 and well like the title says the leaves on my plant are just turning yellow and curling down i havent introduced any nutes too the soil as of yet im using pro mix organic

Yeah man same exact problems with promix and organics!!!!! Frustrating as h$&@!!! I can't figure it out. It's some type of lock up can't b ph there's dolomite can't be cal mag it's in my fulvic acid + minerals I'm left to think it's stress from the cold soil even though my temps r optimal at pot level and air temp my dirt s kinda cold? I don't know what else it could be. I shouldn't have went cheap n got promix I should've stuck to ffof and hf!!!!!!

Identical pics! It happened to me last year with all my veggies outdoors n I tried to give it the benefit of the doubt but I think it's promix people say it's good but every single one of my runs have been s--t with it!!!!!

anyone have an idea of what i can do ???

bump......

well first pro mix has no nuitrents that a N def starting up there please feed than how high is your hummitey / last time you watered

Flush with ph'd 6.0 water because 6.5 a bit too high and make a 1/4 nute mix with a tsp of Epsom salt per gallon and foliar spray. It appears to be a PH and nutrent def problem I hope this helps you out.

also what nutes are you using?

last watered a hour ago
sensi grow A and B
then i have bc bloom bc boost and bc grow
then i have h20202 or what ever its called

also the humidity is at 35 percent

the next time you water test the run off to see what your PH is

Maybe use less h2o2o2 that might be why the plants are stressed.
