Day 39 How much Biobizz calmag is too much?
Had big magnesium deficiency in my last grow even after following the Biobizz feed chart. This time I'm giving them 1ml per litre of water once/twice a week & I'm having the same problems.
I've upped it today to 2ml a litre of water.
Should I up it even more?
Biobizz say to give up to 4ml a litre in hydro, but I'm growing in Light Mix soil.
As always Thanks!
