sometimes this is cause when the temps are lowered. pics would definitely be nice cause this could be some type of deficiency

Naw pics arent needed, it means you have a potasium defiecency, just add some more to ur nute mix and you will be good:bigjoint:

Oh cool bro; Yeah low temps cause purple. I've got some purple on my white widow fan leaf stems that are beautiful and it's gotten down to 65 degrees in my room. I think cold temps slow growth in comparison to high temps; I wonder if the purple characteristics on the is stems always is a for sure indicator that they will develope purple buds as well. but you've heard of ppl sayin they got purp before, it's a desirable thing in a bag

well its a common deficiency. the purple that is caused in some strains do to cold temps is a pure or dark purple and potassium deficiency causes a purplish red color that will be dark on the stipules and a lighter striping up and down the stem.

further more they both happen in relatively different areas.

Alot of ppl will grow a whole crop having this deficiency the whole time and not knowing cus they thing its a "Good" purple but infact it is causing things like internode elongation, miniaturized leave formation and stunted growth rate.

So to answer your question.
Based off his description, yes I will still stand by with a 95% certainty that it is a Potash deficiency, even without pics.

Hey ryder, sounds like you have the deficiency but ontop of that some sort of mold.. cant be sure without pics but soulds like mold.

a quick fix is wood or leave ash if you have a fire place, about a tablespoon per gallon.

but next time you hit the hydro store you should pick up a potash ammendment, Seaweed mix is awsome and has a small about in it, I fix larger deficiencys with my Deuce Deuce which is made by Humboldt nutrience and is pure Potash at a 22 percent dilution(0-0-22) and of course its organic!

I have herd there is home made banana formulas but have no personal experience
