[QUOTE=hydrocannabis;1766491 so lastnight I added 1.5 teaspoon to a gallon of water and gave it to them.
so should this work on makeing my plants greender agen?

and about how long should it take to start makeing my plants greener/healther agen?QUOTE]
I personally think it's a messed-up ph, because it appears like my plants do, when I over-adjust my water. (have adjusted the same batch of water twice by mistake a couple of times, drastically lowering my ph...only done that twice:stoned
I'd try not to water again till you get the ph of the water checked, and adjusted if need be. Since mag sulphate is a buffer, it can help the roots survive a ph imbalance, but IF the cause of the problem is the ph of your water, it has to be corrected before any progress can be expected.
Did you try spraying the leaves with a weak solution (1/4 strength or so) of superthrive and nutes?
Have you cleaned the leaf-litter out? (get ya doin' something while you're sitting there staring at them, lol)
New pix tomorrow?
