Autoflower, 6 weeks today.
Recently started feeding 1/4 doses of biogrow, biobloom and top max.
Guessing nitrogen toxicity? Though, my pH is 7 so it could be that too?
Anything I can do to rectify?
Yes its nitrogen toxicity(tips curling down, dark dark green leaves) She is also showing sign's of "General" nutrient burn. burnt leaf tips. I would say hold off on the next couple feeds and give her just water. Remember you only want to feed once a week and the rest of the time is water.
By a little high, do you mean not too bad?
I'm currently using bio bloom, bio grow and topmax.
Perhaps holding off on the biogrow for the next few feeds?
Soil pH 7.0... I think that's ok isn't it? Don't want to mess around with it too much and end up the other way.
