Zinc Problems?

**Blue61** · 12-07-20, 03:52 PM

Hi All, Hope someone can help me out.Not sure if I maybe getting a zinc problem on my short rider.Only found this on one leaf near the top.Also noticed one finger
of the leaf is deformed with a hook on the end.Gave her cal/mag at 1.5 mil/gal for first time Friday.That seems very light to me and what I used to give to my photos.
Did notice my ph pen was acting wonky that day.Thought it was ok when I fed her though.She also got 1.5 mil/gal of gh micro and grow.
Any advise/help appreciated.

That ain't a zinc issue, that looks like inter vein necrosis caused by too much N

Ya think thats it.Even tho only on that 1 leaf.I know the GH Micro is high in N 5-0-1 actually so a long with the grow 2-1-6. Thought that seemed high.
Thats way I am only feeding half of what the feed chart says which was already cut down for autos.
Thanks man.

That seems to be a good call M_C. Took the girls out of the groom and saw them in real sun light and they sure are dark green.
Gonna be cutting out the micro for a bit. Micro has always givin me some troubles. Don't know why.

They are starting to put out some pistals and to stretch and have read that they need cal/mag in flower to use the p/k properly. Plus I have always given my photos cal/mag
and with them starting week 4 today I thought they could use a wee bit.
