Ok so my high ass edited the original post instead of making a new one lol
lets try that again..
Changed my mind we are sticking to the plan, 9 week chop.. ill start water on Wednesday... flowering is one week ahead and is veg is like two weeks ahead.. 10/14 finishes them out fast..
ladies and gents, what is this deficiency?
my hunch is the because I'm using new coco (not reused/rebuff) the coco is causing an imbalance early on.. because the new growth is good and green..
you have a Magnesium deficiency!!! the first thing to go wrong in pretty much ANY grow. very easy to fix.
you can either use a CalMag supplement OR buy a bag of Epsom Salt (Magnesium Sulfate) on Amazon. I recently bought an 8 pound bag for around $8.00. i highly recommend buying some! its very cheap and easy to use. you can either add it to your nutrient water and get it into the plant through the roots OR, what i like to do, take 1/4 teaspoon and dissolve it in 1 gallon of water, and spray the underside of the leaves. do that once every 3 or 4 days and they'll green up. no more interveinal chlorosis.
