Any ideas on whats the problem or howto sort it out.

P.S. I havnt used any nutes on these babys yet..

Happy Growing!
Howdy MikeOD,

Well...there are alot of questions to be asked,like what's the ph of the water that you're using ? -for starters. Also,are you using a potting soil mix that already has some fert supplement in it ?

How long has it been since you gave them epson salts ? It takes a little bit of time, for plants to respond. They are old enough now,to start giving them ferts..but if the water that you're using doesn't have a ph in the 6.8 - 7.0 range,you will have an uptake problem. If possible,post a pic of the plant in question. Also,did you grow this plant from seed..and if so,was it from bag-seed or good genetics ?

Have a good one...Torog
