Hi, I managed to get my nute strength way over strength 2-3 weeks ago and despite flushing well on 2 different occasions my plants are really suffering and will not take nutrients up and they`re showing signs of what I think is Magnesium deficiency. I`d normally be giving them a week of PK13/14 now and they`d be packing on weight, but they`re looking very lean and lots of the bigger leaves have yellowed between the viens. Question is, will Epsom salts help at this late stage and if so when can I expect them to show signs of improvement and start to absorb some nutrients. Also will it be past the point of beneficially using Pk13/14. Damn, been doing this a long time and I feel like a freakin newbie. Ta guys
