Yellowing, flower/pod drops - What am I doing wrong?
My plants have been doing good for a while, but lately it's started to look a bit sad. I've been thinking that it's just the overdue transplant that's to blame - plants are crowded in under my lights, too big to get proper light all over, root bound and so on. However, I do keep some on the windowsill as well, where there's good lighting, but these plants also seem to be plagued. So, I'm wondering if I'm doing something wrong. Here's the symptoms I'm seeing:
Yellow leaves - Mostly the lower foliage, but some plants have yellow leaves all over
Leaves dropping - After turning yellow, leaves typically drop
Flower drops My plants are dropping a lot of flowers - most of the new flower growth drops
Bud drops The past few days, several plants have dropped small pods, while bigger pods on the same plants have stayed.
Brown/wilted spots on leaves Some plants have developed brown/wilted spots on leaves, which eventually turn yellow and fall off
Generally, it feels like my plants are a bit stressed, but I'm not sure exactly what's wrong? Too much water? Too little? Too little light? Fertilizer issues? Can these be symptoms due to plants being excessively root bound? Many are, but I thought that would only stunt their growth.
Another worrying sign I saw today: One of my finest Habaneros, which is now in a 17 litre pot, is showing lighter colored/slightly yellow new growth. Is it missing some nutrients? (See picture)
