Nutricients biobizz question

NK def

2ml of fish mix with every feed will lockout your plants. Too strong, they will burn. I grew with 10% additive of worm castings and i fed 0 nutes during all grow. I had strange results with fish mix, i dropped it from ratio, just bumped biogrow to 4-5 ml/l. Rest is ok, its almost impossible to overfeed with biobizz if you dont use fish mix. I found theirs calmag unpredictable too. growdiaries.com/diaries/164021-grow-journal-by-asnoriu Thats one of 3 girls from 0 feed round. I was starting to feed only on week 4-5 with all mix soil. Was feeding every second watering, always slowly , for better irrigation and with small run off ( to prevent salt build ups ).
