Can someone tell me what they think this might be. Has me stumped.
could be the start of heat stress
whats the temps, PH, of your cab?
dunno exactly but I've got the same thing on a few leavesand here's what i think it might be. Heat stress due to magnification of light from very small and repeated condensation drops on surface of leaf.
It is only appearing in the middle canopy and to few leaves. Temps are 76 on the canopy, but the 400 is only 8 inches away, but is insanly aircooled. (can stick my face on the glass with comfort). Could be the magnification thing. That would be a relief. Peace
Ph is 5.8 water temps 65.5
