Twisted Leaves on new growth, need help
Hey all, newer grower here, having some issues with the plants. the tacoing seems to have started once I changed them from florescent to metal halide. first thought was heat or light intensity, so temps had never gone above 80, but the MH was rather close at first. I am in a sealer room running CO2. I am using foxfarm Grow Big, on their first watering in 5 gal pots I did 3 teaspoons per gallon, then about 10 days later they got 2 teaspoons a gallon (which was on 12/18/18). After the first big feed, the leaves were exhibiting twisting/taco-ing and sort of blistering (which i thought was light intensity for a bit) since then ive been giving them regular h2o, which i used ph test kit to bring the ph down a bit, my normal h2o seems to be right around ph7. They were dry this morning so they just received 2 gallons of straight RO water (first time), hence the droopy leaves in the pictures. As you can see, new growth is rather twisty and tacoish.
Also, this is my 4th grow in this room, others have turned out fine not PHing the water and using the same type room setup. all runs have been a different strain. the most recent run, last winter, apparently we had broad mites. since then ive had no plant material in the building for 8 months, disinfected, bleached and pesticides on everything and obviously clean everything a few more times with bleach. also once i started these from seed, a few weeks in, i used a few cycles of the N. Californicus predatory mites that are supposed to seek broads and kill them. I see no visible signs of eggs on leaves under a 150x scope, and the plants arent acting the same as i remember with broads.
I'd love some input from you guys here, much thanks and appreciation!

How often are you feeding? currently not feeding for 2 weeks
If flowering, when did you switch over to using Bloom nutrients?
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
What is the TDS/EC/PPM of your nutrients used? no meter
What is the pH of the "RUN-OFF"? no meter

Tell us about your ventilation, intake exhaust and when its running and not running ? one fan for lights pulls cold air in and pushes the warm air out of the room, none of this air is for the room, just to cool lights. 6" fan with scrubber circulating in room. have an auxiliary 4" fan hooked to a thermostat to pull air out incase of overheat. two fans mounted on wall blowing about 2 feet above canopy.
Is the fan blowing directly at plants? no over top
Is the grow substrate constantly wet or moist? dries slowly

If using tap water, what is the ppm/EC/TDS of the water right out of the tap?(Only if you have a tds pen) no meter
If using RO,Distilled,mineral water, what is the ppm/EC/TDS without any additives?(Only if you have a tds pen) no meter
Are you using water from a water softener? no
Has plant been recently pruned, cloned or pinched? no
Have any pest chemicals been used? If so what and when? no
Are plant's infected with pest's? under 150x I see nothing
