i am using promix hp medium to grow indoors with cfls and i just have a quick question about the medium. after about a week or sothe leaves started to turn brown and black and brown spots on the leave tips. i transplanted them out of the small pots into bigger ones and added worm casting to the medium. the next day the leaves went striaght up and look good just wondering why thye did that in the small pots.

i was thinkning it was becasue there were nothing left in the soil for the plant but dont no for sure can anybody sort me out with this?

With pics, we'll have your answer quickly. W/O, it could be a number of things. I've grown in pro-mix for many years and I've seen it all- the good and the bad.

How small were the pots, how big are the other pots, how long have they been in there, how old are the plants, do u add lime to the pro-mix, do u have holes in the bottom of the pots, do u pH the water, do u check the pH of the run-off after watering, how much light, what's the temps and humidity, fresh air?, how often do u water, leaf problems start high or low on the plants......... that's a start.
