Robertsanswered grow question a year ago I looked at your diary. Your 1st issue is your ph of 6.2 needs to be 5.8. It's lock out over 6.2. You can use your solution they are growing in now to buffer it for cal mag. But it will be needed the whole grow. Coco/perlite grows are 5.8 ph in and 5.8 ph out for best results. Heavy irrigation grow. It is to never dry out, but never sitting in run off either. I have grown in coco for years. Feel free to dm me if you need more help.
