Hey. So a week ago I posted that that two of my plants were showing this weird behavior of old leaves turning yellow from outside. Now almost all except the newly planted clones are showing the same problem.
I have been flushing them with pH-ed water (someone said it is zinc toxicity) but that doesnt seem to solve the problem.
The only feeding is either fishmeal/bone meal dusting I slightly mixed in the soil or the foliar spray of my planted tank water.
The soil is a mix of peat, coco coir, top soil, a teaspoon of fish meal and bone meal per sq ft, perlite and aged cow manure (not more than 5%).
I over fed the plants when they were young with NP heavy fert when they were young but havent done so since 3 weeks.
