the strain is AK its been 2 1/2 weeks since 12 12, im in FFOF temps and humidity right. Ive feed bloom nutes once at 25% and I give cal-mag every water being im in RO. Ihave 5 of these plants all feed the same only one with this issue. only in the middle leaves of the plant.
Looks to me like a really bad calcium deficiency but could also be ph issues. Are you phing your water? I hate deficiencies because they're so hard to tell apart.
Sorry. Jumped the gun. Noticed you feed cal mag. Probably a ph issue. Does the ro machine ph neutral the water? I know it takes everything out mineral wise. Don't forget it's not about fixing the old leafs its all about the new growth. Those leafs are never gonna recover. Is it spreading does it have those on the new growth?
no not on new growth, I always ph my water6.5-6.8, my first thought was calcium def. as well but I feed 1tsp per gallon. Also tomorrow is feeding day should I just go along with regular feeding
