4th week of flowering. I lowered the lamp at 30 cm above the canopy and plants didn't like it. After few days raised back to 40 cm.
Upper leaves of Purple Punch look bleached.
Reducing nutrients to 1.5 ml/l.
Very healty looking. I'd suggest getting some fans under, push the against the wall to draw that 50% humidity air circulation into and under the canopy. Ounce of prevention is worth a pound of cure. Get ahead of any mold issues by preventing microclimate inside.
@Sirdukevonwalter,
Thank you for your advice. I put small inline fan on the floor and it moves air under the canopy. And I thank you for answering my grow question. Awesome explanation - simple, easy to understand and with useful insights and tips. This is what I was hoping for. Thanks to you I gained more confidence, because most of the time I feel like I don;t know what I'm doing, and you helped me undrstand what's going on with my plants. You were absolutely right - I fell for 2 feet colas ;), and you were right about growing different strains in one tent, because Tropicanna was closer to the light than Kush and doesn't seem affected (yet). Once again thank you for your help. I really appreciate your time and effort. Happy growing.
@Oakash777,
Yes. PH is OK, but runoff EC is different every time, and I don't know if they are hungry or overfed. Next time I'll grow organic, possibly Natures Living Soil.
