My plants are a month old and are on their second day of flowering. Today I noticed that a few of the lower leaves on one of the plants had these strange light colored, almost light brownish spots on them. Anyone know what the cause could be? I've used water soluble 24-8-16 fertilizer twice during vegetative growth and 15-30-15 on the first day of flowering which was yesterday. Soil has no added nutrients.
Im asking you if the fertilizer you used that has an NPK of 15 30 15 was miracle grows bloom booster?
mine is about the same age as yours and i has similar spots, luckily mine was just a case of it needing repotting seeing as its cleared up nicely
