Serious Nitrogen toxicity there bro.


It is healthy and normal for the plant to start showing signs of nitrogen deficiency near the end of bloom. The worst thing to do is try and compensate. Nitrogen through the first half of bloom is great but it has to taper off fast.

All three basic signs of medium to heavy Nitrogen toxicity are there and the advanced sign is showing as well.

If you are in soil you should do a heavy flush. Those leaves probably will not recover just hope for the best and feed lightly if at all. You are close enough to the end that you ' need much if at all if you are in soil.

If you are in hydro you need to cut down to not more than 1/4 nutes after dumping the res. maybe start the real flush and get some clearex in there.

Check out the EC line here. You are likely near the end of bloom.

VI is correct on all counts. Flush, then stop feeding nutes with nitrogen. Water and sparingly use nutes formulated for blooms until harvest. These kind of nutes have little or no Nitrogen.
