Should I be worried about the discoloration on just one on them. Personally I think it from her having cooler temps at night 64F {18C} or could it be from my lights it a HLG 600 Rspec it does have a dimmer switch I have it set 70% not sure there's no % on it so I am going by all way to the right 100% so 3 clicks to the left would be 70%. Height is about 24" and that's about the highest it will go....what to do ????
UPDATE: DISCOLORATION
Problem: leaf discoloration
Medium/grow method: soil- mix with fox farm ocean forest/fox farm happy frog. Added lime with soil mix
Feed: and supplements used: formula II (bud and bloom) from a local fertilizer company
water source: drip emitters , hand watering. Drain to waste
PH in the root zone: 6.5
Strain/age: White Widow auto - 2-3 weeks flower, 50 days from seed
light used: HLG 600 Rspec - 20” from canopy
Climate: 5x5 tent, day temperature 75-78F (23-25C) night temperature 64-69F (17-20C)
Additional info: noticed leaves was getting light green color like maybe light bleach so I turned down the dimmer. The next day I seen it was progressing a little not by much. I really can’t get a good picture of just that plant alone because of a back problem recently.
