leaf problem.. worried first time grower!

Wat is pm. Wat the hell is the reat of that paragraph about. I am a beginner and have no clue wat you are talking about.

You have to decide what has caused the deficiency, it is either wet soil or nute burn causing the lock out. Agree Cal/Mag will help providing plant will take it. If your soil is very wet I'd dry it first to get air to roots, if not I'd add the Cal/mag soonest but would leave adding the other nutes until you see some improvement.

So dont you think there is a nitrogen def... loosing a lot of green in the plant. .. I flushed them two weeks ago. Am lost now going to put cal mag at next water with a dose of grow I think for the nitrogen.. what you think
