Yeah, not sure myself. I thought it was lack of sun so I moved it on my bench. Maybe a watering thing? Too much water? Too little? Maybe needs more
This is the 1st year I've been dealing with increased interior yellowing.
I should run a soil test, but have began a liquid chelated iron supplement assuming chlorosis.
Several things can factor into chlorosis, including disease, and use of pesticides.
Root issues from overly wet, to being compacted, and or lack of certain nutrients
also are causes of chlorosis.
This is also the 1st year I've had an infestation of spider mites, so targeted pesticides have been used.
The prophylactic use of pesticides is nothing new for me, but I did introduce a miticide I'd never used before
given the infestation and discoloration of the foliage due to the pest.
As well, this is the 1st year I've omitted rotating in Espoma Holly Tone, worked into the top soil.
Between the other 4 or more fertilizers I'm using, I kind of doubt the lack of Holly Tone is culprit on my bench.
Only problem with the liquid iron is that it's a once/month application, then reassess if you need more or not.
I only have 2 more good months of growing opportunity to decide if I need more or not. Then another year begins.
When I remove dead or near dead foliage that is ripe to brush off, if it requires a tug to remove, resist the urge to tug.
Often there are new buds at work already, and latent ones could be dismissed if you tugged instead of cut.
