Yellow/Purple color on lower leaves

mj402 · Jun 14, 2023

Hello, first time grower here and I'm doing an outdoor grow. I feed my plants nutrients weekly and they are a little over two months old. I am starting to notice this yellowing of leaves with purple/brown color coming from center of leaves outwards. I have seen someone say it may be a phosphorous deficiency. There are also what looks like very faint white specs on the upper leaves, not sure if related. Just looking for some more insight.

Thanks

So I believe I found the culprit but if anyone has more insight please tell me. I believe I had spider mites, I tried to rub any leaves that seemed affected on both sides Hopefully I squashed most if not all aswell as their eggs.

However, would they be the cause of this yellow/purplish leaf discoloration? Or would it be something else. Thanks.

I try not to water them until the soil feels dry about a half inch to one inch deep. I felt like I was overwatering them in the beginning. They are in 7.6 gallon containers with holes in the bottom for drainage. I usually water them every 3 days.
