We can’t really give you a diagnosis without knowing the pH runoff. Do you own a pH meter, or pH testing strips?

But, from what I’ve read, it sounds like you might be over feeding with nutrients. Can you post a picture possibly?

I need to know what soil. If it comes amended with fertilizer, then adding GH 2-opart is causing the issue. You are making your soil too hot for the plant.

You need a TDS meter for measuring strength of you solution after mixing it with water, and you need a PH tester in order to make sure your PH of solution is 6.5-7.0 PH

Awaiting your reply. :slight_smile:

I’m using Espoma Organic Potting mix. As far as getting these meters, i’m on fixed income so i will have to wait another week before i can get them
