My plants are 6 weeks into flower. They are 95% yellow now. I recognised it to be a nitrogen Deficiency around 1.5 weeks ago because the shop I bought my set up from told me I was using the wrong nutrients (their advice!!). I've bought the correct stuff now containing nitrogen and potassium and all the good stuff and started adding this 1.5 weeks ago but have seen no change. Any advice? Are the leaves all too damaged and as such are irreparable, so new growth will be the only stuff which shows signs of green? What will the effect be on the strength and yield?
Once a part of the plant is hurt that deep into flower it will not recover to the green state it was. Try to finish it out as best you can and pull her. R-4808N
It's not ideal but with a good flush you should have some weeds and while runs worth of experience on what not to do before you consult the forums. GFP Sent from my SM-G600FY using Tapatalk
