Hey all, I'm wondering if anyone here is able to tell from the following pictures what might be going on with these plants. Thanks for any help.

I started with Ocean Forest soil. I added some organic worm castings about 25 days into the grow which I think brought in some gnats. I have pretty much eliminated the gnats, although I still see a couple here and there. Today I added fertilizer again (this is now about 35 days since I added the worm castings). I used a mix from a grow shop here in town, FloraGrow Bloom or something like that.

I was getting this same discoloration on a lot of the large leaves that were from the first half of the veg phase. I clipped many of those leaves because they were deteriorating a lot. That all took place during the veg phase.

Now I'm going into week 2 of flowering. I've taken a picture of many of the leaves that are still on the plants as of right now and show signs of distress. Many are showing a discolored area between the spines on the leaves, accompanied with some shriveling and in a few cases parts of the leaf seem to have just fallen off completely. On one plant there is a new growth leaf that is almost completely yellow, although this seems by my judgement a different problem.

EDIT: The yellow leaf I mentioned at the end of the post is the final picture. The strain is Purple Train Wreck.

EDIT: I copied this thread to the "problems" thread. This one could be deleted, although I can't find the option to do so.

It's kind of hard to tell with the photos as they lack any color. There's some tricks to get more color, magic>pop art for my camera or when the lights are off.

From what I can see it seems like a cal/mag problem, but in a couple pics, it appears there may be another issue " pic 233737", if so it's likely ph related. In either case, some dolomite lime will add cal/mag and stabilize the ph, but it can take week or more. For a quicker fix you can use some cal/mag supplement, there's some cheap alternatives like epsom salts if you are strapped for cash and just add in your next watering if you've ruled out a ph imbalance.
