Looks like calcium deficiency starting on lower part of the leaves. .1ml seems low but I'm not sure the source that you are using. 1ml per litre of water should help correct this in 7-10 days.

Orange spots?!Can anyone tell me what these orange spots are on my THC Bomb autoflower? They're only on one leaf (the very first one) - the plant has since grown and there's no further sign of it... should I worry? Grow medium is ProMix, using Fox Farm Grow Big (lightly so far).Leaves. Other

Plant starting to yellow too fastThe crystal meth has started going yellow very fast. The buds still have at least 2 weeks of growth needed to fatten out and pack the trichomes with thc.. I know it is normal to start dying but isn't this a bit early? Should I let her keep going as long as sugar leaves are alive?4y ago
