That angry face loool - Just to clarify ... I like biotabs .... "when they work" ..... but clearly on this plant either the tabs havent broke down in the right place, or the plant for some reason just hasnt eaten them .. or an imbalance of nutes in the tabs has caused a lockout.
I used biotabs for many grows in my efforts to put in the bare minimum effort lol - and now i don't
Waiting for a tab to break down to feed the plant at its hungriest time on it's last innings ... in my mind... wouldnt work well.
