So I have three plants that are at the end of the 4th week of flowering. Things have been going fairly well so far but in the past three days I have noticed some yellowing in the interior of some of the upper leaves of a couple of the plants. It is most pronounced on one of the largest plants. I have a picture of the issue below.
A week or so ago I upped the nutes (FF) from 1/4 to 1/2 strength when I was seeing lower leaves yellowing and thinking I was maybe dealing with a N def. It stopped an issue I had been having with larger leaves at the base dropping but in the past week I have been noticing the yellowing on some upper leaves as shown in the above pic. So yesterday I leeched my plants running 4 gallons of water through each followed by 3 liters of full strength feed.
Also, run-off was tested yesterday during the leeching and came it at about a ph of 6.0.
Do you guys think I am on the right track? Any other thoughts? Being right in the middle of flowering I am worried. This is my first grow but it seems to early to be experiencing normal late flowering yellowing. I am scared of losing the harvest!!!
