Absolutely nutrient burn related. I agree with high roller. Water only next few times then dial back on the nutes some.

Brown/yellow spots
I have noticed some spots and yellowing of older leaves. Do you think it's Calmag deficiency, nutrient lockout or maybe nutrient burn ? It's autoflower in 3rd week of flower. I was feeding only Biobloom (4ml/l) and Bud Candy (2ml/l). I cut back and did watering without nutrients.

Veg crisis - Auto Blueberry and Strawberry banana
Hi,my plants are in the middle of a crisis. I’m thinking i might’ve over fertilized them, (fish mix-biobloom 2ml per plant in 1l water). Can someone help me identify the problem and help me understand how to fix it? I was thinking maybe a zync deficiency. Thanks!

Disease or Deficiency? Or something else?
Red spots appear from bottom up & now at very top, I think they had nute lockout before from underwatering & silica buildup, watered w/ calmag only last 2 waters, top leaves have burnt edges, some leaves came off. Runoff PH was 6.9. Leaf septoria, nute deficiency, something else?
