Hey guys˜!
This is the 3rd time I have the same issue.
Can't point the problem.
The veg time is awesome, quick growth, no burns, amazing leafs:
As soon as 12/12 starts, leafs begin to burn, without any environmental changes:
Than goes downhill fast:
EC is 1.2, PH 5.8, straight coco.
Temps 27C, RH 70%, good VPD.
Jacks 321 with RO water.
The lighting is a custom DIY panel with 2x Phantom Boards @ 2 amps, 10x Clu048 1212 cobs 97CRI @ 1 amp.
Everything dimmed down to around 30.000 lux.
Sealed room with CO2 only dispensing enough to maintain around 500ppm, not boosting. Exhausting 15min every 2 hours.
I don't know what to do...
