J_Kushanswered grow question 1y ago It's not the thrips. The damage to the plants is hardly noticeable. Your leaves can have various causes, but definitely no deficiency if the information in your diary is correct. Something is off with the pH of your soil.
A) Are you possibly watering too much and causing waterlogging in the pot? Check the weight before watering to see if it might still be damp at the bottom.
B) You might be fertilizing quite a bit. It could also be that nutrient ions have accumulated in the soil and are now affecting the pH.
I would just give water for a week, remove the affected leaves, and then go for a maximum of 5ml up to 10ml NPK vegi/bloom, it doesn't matter. The phosphorus difference doesn't play a role.
I hope it recovers. It's a gem!
