Having trouble diagnosing the issue, check it out?

Hey y’all,

thanks for viewing my post.Was getting ready ti flip into flower this weekend but seen some problems with my plants and wanted to wait a few days and check it out. May just end up flushinv then start flower this weekend on a clean slate. What do you guys see in these photos?


3 different plants, two have similar issues and then one is only having issues on the edges. Haven’t seen anything like the one with the problems on the edges.

Anyways, I’ve checked out all the charts etc and theyjust don’t seem to match100%with what I’m seeing so I wanted another paid of eyes and brains.
Thanks

Magnesium deficiency.

The last pic doesn't have any signs of Mg def. My guess is pH, but more info would be helpful.

Medium is coco

Feeding with floraflex veg A and if anything going light in the feedings. I’ve used gnatrol a couple times for preventatives

water is from tap, used it for about 4-6 grows now everything has been fine

I let the coco dry out once or twice but not enough to induce wilting, so if everything ends up going smooth, then I’m going to guess that was the problem with using crystal Nutella and coco that got a tad dry but like I said, they weren’t even wilting so idk

Some extra photos

Mag. deficiency! 1 ml. Cal mag per gallon of water give it couple days you’ll be good.

Try looking again. Even in the background of one it’s more obvious.

Coco should not get the least bit dry...........it should always stay saturated.
You should be feeding to run off daily........never plain water.

thanks everyone and the coco usually doesnt get dry, I just hadnt set up my auto feed system yet at that point in time and missed a watering. It would seem that I upped my lighting dial a little bit and the plants needed more mag and wasnt getting it since I was light feeding

definitely mag deficiency. whether it's due to underfeeding or pH issues I cannot say. I was just having the same issue in my tent and bumping my Temps a bit and upping my calmag sorted it out quickly.
