Drip
T5
Distilled water @ 5.8
69-72 F
40-42 RH
18/6 cycle
Watered 3x daily @ 10 min. increments.

These 2 are in the 9th day of light. T5 sits 3-5 inches from top of plants. I've noticed they have slowed in growth and developed leaf discoloration. From what I've researched it looks like a P deficiency. Is it too soon to have nutrient deficiencies...?

Before I forget - what about the roots? This setup is strictly vegetative, when the time comes they'll go into a flower room. The roots are starting to poke through the bottom of the rockwool...:wtf:Whats a good method to keep them in the dark without adding hydroton or anything that will stick to the roots?

Thanks!
