I’m just finishing week 4 since the flip and I have had a few issues with my clones, the mothers are in the same flower room, same everything and they are doing great
Two Optic 6 600W (true watts) lights
50/50 Coco/Perlite in autopots.
Advanced Nutrients pH Perfect Sensi Bloom (A&B at 2mL/L) + BigBud (at 2ml/L) + Cal-Mag (at 2ml/L) for a total of 1250ppm and a pH of 5.8-6.0 (the reservoir drifts up over a few days). I checked the pH in the Autopot trays at lights out this morning and it was 5.8
Temps are min 20C lights out and max 26C lights on
RH at 40-50% lights on and 60-65% lights off
This is probably the worst affected top, any ideas?
More pics and some history in my grow log
