I have a Powerplant grow just entering its 3rd week of flower. About a 1.5 weeks ago I started to get yellowing of the leaves near the bottom. From pics on here it looked like either a N or Mg shortage. I read that powerplant in particular uses alot of Mg during the stretch period of flowering. So I gave it a dose of epsom salts (1 teaspoon to 1ltr) and an extra ml of grow to the 1ml Grow & 2ml Bloom mix (ot1) I've been feeding it every other water. However the yellowing started spreading up to the middle and now is at the top! Nearly all of the leaves below the top have died and fallen off and now its affecting these top leaves too.
As this is only my 2nd grow I decided to use this plant as some training for some LST bondage. I got lucky when she turned out to be a lady. I've about 8/9 bud sites and up until now was very proud of my little baby. She looked healthy and was responding well to the training. I thought I was starting to get the hang of this growing lark but now I'm afraid shes going to go belly up or it'll seriously affect the size and quality of my bud. Anyone got any advice?
