Its iron diff....buy some cal/mag add 10ml per gal tell it stops, then just use 5ml per gal..add it when u water every time..good luck.. Meangreen.

its a calcium magnesium supplement that has iron in it too..most water doesnt have anuff in it for growing pot..iron diff always start on the top of the plant thats how u can tell..u can spot most diff by were they start ( bottom or tops of plants)...meangreen.
