So I'm having trouble figuring out why my plants new growth is browning. Strain is Blueberry Spacecake, lights are LED 1200w with cobs. Medium is in coco/peat with vermiculite and perlite amended with worm castings. Ph is 6.7.

Yeah I just mixed up 16 gallons of water with a full lemons worth of juice to drop the ph, nutes are 20/20/20. I feed, water, water, rinse and repeat.
 
Even when all the nutes are bound in nitrate form? Except my CALiMAGic it is liquid, also my tap water comes out at pH 8, hence the lemon juice, any efficent way to get distilled water without purchasing it or having to boil pot after pot of water?
 
Ah okay, I think I'll stick with DWC when it comes down to starting it. Also these are my veg nutes.

Coco has no nutrient retention

Water daily with 1/4 strength nutes till runnoff

2+x a day in Flower
I assume in veg just nutes once per day?

Also my nutes have been mixed 6.25 tablespoons of plant prod into 22.5 liters, and the calimagic is think was 6ml to 22.5 liters
