Multi-micronute def.
Potassium most evident.
You are underfeeding and possibly overwatering at the same time.
You aren't seeing bad N def possibly because there's a bit in the soil still.
Potassium is very important to a plant's immune system and in humidity like you have you are set up for fungus... I fear it may already be an issue but can't put my finger on it.
You are also ready for bigger pots and this is a time to repot into light soil- again because of high humidity it is IMPERATIVE that your soil drain exceptionally well.
Foliar feed micros wiht something like Algoflash or GH Micro.
Get a more powerful extractor fan in there and look for standing water under your pots too.
You need to dry out your room or you will never be able to flower properly.
