No problem Brother! Anytime!
I do PH all the R/O water I feed my plants.
I don’t like fungus gnats, so I only feed them what they need for the day. After they germinate I moisten the coco with about 8 ounces of water and only feed them a turkey baster full each day, the second week about a cup, and about 8 ounces the third week. Keep in mind, each individual plant will intake water different and it will also depend on your environment.
If you’re interested… you can check out the ILGM GG-4 crop I just posted. I used less than $10 worth of dry amendments for the whole grow.
Please let me know if you have anymore questions.

Thank you again man. You've been so much help. I will definitely let you know if I have any other questions homie.
