You should be cautious about grow and fishmix, especially if you give them together! In contrast to the popular opinion that you can't severely overfeed with
Biobizz you can. Easily.
I would drop it altogether till chop or signs of N deficiency, your soil and plants should have lots of N left.
Made this mistake years ago cause I thought this "organic" stuff couldn't do severe harm. Then I began testing ec and was baffled.
Test the ec of your solution,
Biobizz grow or fish especially has a high salt content/ec (forgot wich one it was, perhaps both...).
Most of the
Biobizz nutrients are readily available to the plant, no need for anything to get broken down. So you can just give it based on need, it'll kick in just about as fast as mineral nutrients do.
