Leaves Green, but Twisting, ALL INFORMATION INCLUDED!

If you need I can take pictures. The problem is simply this..on the newer leaves that are growing in, the middle fan leaf is spiraling. That's the only leaf.

sounds like you got a mutant. If more then one plant is affected then I would say your ph is off.

PH is at 5.5, I let it drift up a bit to feed in other nutrients. GHS grows theirs at 5.5ph, and I see thousands upon thousands of posts here, and elsewhere, of others using 5.5 ph. My plants look wonderful, except the random leaf with the center petal spiraling.

ive had random leaves that did that but thats only cuz the way they first grew in. nothin bad happened from it

Twisting leafs is due to a magnesium deficiency.



Notice how some non-yellowed leaves are twisting or turning over.

I have experienced this on most of my plants since I started. Very easily fixable. Make a epsom salt and water solution. Use hot water, and mix one gallon of hot water (not boiling) with about a tablespoon of epsom salt. Use a spray bottle and spray directly on top and under the leaves.

Problem should alleviate within a few days.
