Hey, i'll try to point you in the right direction.

Sounds like you've got some problems with your nutes to me, a lot of people don't like MG for mj, get something thats meant for mj, look see if you got a hydroponic store nearby or there's places on the web. Maybe a problem with your soil, what type are you using, i use a pre-mixed soil meant for mj although you can mix your own, but you must know what you're putting in there coz it can have an impact on ph etc over time. If you let the guys know what soil you're using someone more experienced will hopefully know about it and any problems that it may have.

Take a look here Charts, Guides, Graphs and Goodies You might be able to work out the problem with the charts. Also try googling "cannabis sick plant guide" there's some good info out there with pics, you may spot something that looks just like your problem.

Good luck! :rastasmoke:
