rhodes68answered grow question 4 years ago Seen this with bio-bizz a few times
So I am just going to go off the leaves as not real happy with the stuff when I used it.
Looks like calcium deficiency and nuet burn to me.
just brain storming... Sometimes happens when people use too much Cal-Mag in response to a ca def
Sometimes its the nuets, looking at you bio-bizz
Sometimes its something amiss in the soil.
Thats what the leafs say anyway with burnt tips and CA spots
