I like to know all of these little details so i keep them in a notebook.
Did I say that? That is not what I meant. CalMag plus is what I recommend with every water change (but flush) as preventive measure for those of us who use RO water.

The Fish shit is extra Manganese when you have a problem like Marc was talking about. If the plant needs a shot of Manganese only that is a cheap source.

I would not use it all the time unless you are growing Organic and then it's only a supplement you add to your other nutrients.
Zandor Reviewed by Zandor on . Zandor please take a look You had mentioned before that 'rust' on leaves may indicate a Mg deficiency. What's your take on these examples? I've got the pH taken care of and right after that the growth was good with all leaves 'at attention/no droop' but it seems like this is spreading. Was just older growth and now hitting some of the newer growth although not the newest growth. Been in flower (from first pistils) for 19 days. Have given it a diluted dosage of Scultz 10-54-10 a few times. Thanks for any Rating: 5
