Onandonanswered grow question 4 years ago Hi. After checking out other pictures online, they all mirror my leaf issues and stem from potassium.
Until flower is used RQS easy grow - booster.
Hydrolized protein 30%
Leonardite humic acid 20%
Lithothamnium seaweed 20%
Potassium sulfate 12%
Magnesium sulfate 3%
Calcium bi-carbonate 15%
Then at flowering moved over to approx 1ml per L of BioBizz BioBloom.
Ph run off is 6.3
Thanks 🤩
