I used blue lab but tbh I started using recharge over 2 years ago and I grow with coco coir and use canna coco nutrients haven’t worried about ph since the recharge and I only use 1/2 teaspoon per gallon nutrients mix once a week saves so much time and effort recharge is my go to plant doctor lol seriously I recommend giving it a try
