First off, I would like to say thank you to everyone on this forum. This forum is an invaluable tool!

Problem:
My girls are throwing a temper-tamptrum and they are looking like they are suffering from a deficiency of boron or copper due to the reverse osmosis water coming out at 0 PPMs. They were planted 32 days ago.


Soil:
80% Fox Farms Oceans Forest
20% Perlite
7 gal smart pots

Watering:
0PPM reverse osmosis water to start (tap water is 40-50PPMs)
CalMag Plus added 4 Tbsp a gallon (started 2 weeks ago)
Each 7 gal gets 3 qt then another qt about an hour latter
Watering every four or five days
PH is in the low to mid 6s, I use a color test right now
No fertilizer has been added except CalMag

Envirnment:
2x HLG 550 set to low, together they pull 400 watts at the wall
5x5x8 Tent
1x 16" oscillating fan
1x exhaust @> one air change a minute
70-85 degrees hovering around 80 most of the day
50-55% humidity most of the day, nights are closer to 60

What do you guys think? Pictures attached.
