Curling under

[CiderSpy]

I would say the lower branches look like this and is much less to no under curl towards the top.

Oh what's this mean again ? the under curling of the fan leafs.

The tip of the leaf looks brown, is that correct? If so, could be the "claw" effect from too much nitrogen.

Too much nitrogen is possible, thanks for the heads up.

Remember that some strains are prone to curl under. Blueberry or anything crossed with Blueberry that hasn't had that trait backcrossed and bread out.. Not saying you don't have an issue, just giving you another tool for the tool box..

I just know it's not from over water. not all feafs are curling and there not burnt so, maybe the strain. I will cut back on the nkp abit (merical grow)

If you are running to high a PK, you will cause lock out and get very little ATP production out of the plant. I only use a PK boost for one week during flowering. That is the only time I would use a product that has a double digit rating for either PK..
