Hey Micwalk, its something they have in the hydro store that is another product from advanced nutrienets in a white bottle with a big red cross on it, supposed to help your plants thru shock, and lots of other stuff, was gonna get some and try it, but ended up getting my new ebb and flo system instead, couldnt pass up a very good deal, 400 instead of 6, saved 2 yahooo...
http://www.advancednutrients.com/hydroponics/products/revive/revive_product_information.php so I guess i keep babying them and if they dont come out of it, then hopefully my clones will do ok,everyone keeps telling me its lock out, even the guy in the hydro shop and a plant shop I took a couple of leaves with me, surprised I didnt get booted lol...anyway, no one was in the store when I showed them the leaves so I dont think it hurt anything....fingers crossed...so he told me how to feed them and gave me a measuring cup with mils on it and a feeding chart and marked when and how much for what I am doing ...said in a couple of days they should show signs of better, so now I have the opinion its lock out and /or a deficiency...what have you tried to do different than what you are doing?...you keeping your room under 80, you have fans, your not over watering, I guess eliminate what it isnt then try to figure what it is...
If your ph is ok, your water is kept cool, you have fans, your not over watering, and the light is not too close, what else?? could it be...
you couldnt identify from the urls I sent you? for plant problems?
