10-12 ago a few top big fan leaves at the main colas (under the center section of the led panel) started to turn light green between the veins. I didn't pay much attention as the plants generally looked happy. Gradually, the discolouring extended to more top leaves, and now there are several yellowish big top leaves at both plants.
3-4 days ago I thought it was some kind of defficiency (nitrogen / magnesium / iron) and I upped the CalMag and the Micro-Bloom dosage. Did not see any particular improvement, so I pulled up the ligths at 60cm from the top buds. Still no clear sign of recovery.
Any ideas?
