Brown/yellow spots
EaRtHstarted grow question 6 months ago
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.

I often got calcium deficiency on my Fast Buds autoflowering plants in mid flowering if not given CalMag. I would put my money on calcium defiency rather than nutrient lockout or burn.

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.

What do you think the problem could be?There’s something going on with some of these plants and I can’t seem to identify the problem so far. I have been doing a lot of research and I’m in a process of elimination at the moment but the plants growth hasn’t been affected. I will continue to try treat the problem.
