My second grow same problem.

Look at the leaf i have just removed! I'm growing in soil i'm not over feeding temps are ok, ph is between 6.2 and 6.4. I thought it was mg def so using 1 tsp of Epsom salts per 5litre of water. This started to happen about 10 weeks or so in. HELP!!

This happened first time round and had to chopped a fews days early as was making the buds go crispy.

Any advice will be appreciated.

Forgot to mention i'm using Ionics.

too much food. any pics of the rest of the plant. more info please. but is the rest of the plant like that.
my first grow went a little like that. i was using hydro food insted of terra/soil. the shop had sent me the wrong stuff. anyway i used it and its twice a strong a soil food, and i used to much. hoping my plants would grow bigger/faster. stop nooooooooooo.
more food doesnt work, it just kills, hope you have pebbles in the bottom of your pot so you can flush. epsom salts. if its not temps or over feeding i dont know. any pics of the whole plant. is there like build up growing under the fanleafs. thats build up of food, that the plant cannot expel, also are you using a fan?. that also helps to expel the plants crap.
