Yeah thats interesting. Your plants look good overall but its good to pay attention to those subtle signs. I think they do indicate something! I wouldn't worry too much about the yellow edge because that might be from water droplets but I do believe the interveinal yellow can be fixed.

I would suspect manganese, but perhaps molybdenum, sulfer and maybe even copper could help. My plants often look similar and those are my usual issues. Flip a coin about my advice (and even if you got a tissue test you could still flip a coin... these issues can be very transient and might not be identified by the tissue test depending on the weather or soil moisture, and/or the leaf stalks might be in an adequate sufficiency range because they get first dibs on the nutrients ahead of the interveinal areas.)

Don't burn up your plants applying large doses of anything. Try very small doses. Its a game of whack a mole but it does feel great when you do see an improvement.

That being said, you could apply the correct nutrient but not see an improvement. Manganese is slightly mobile so a chelated manganese product probably would show some improvement. You could apply it at a low dose of chelated manganese just on that leaf where your finger is, then you wouldn't risk applying the wrong nutrient to the entire plant...

That's the most foolproof way to do it. Good luck.

This just made me wonder - Anyone ever cross an AG with a Venus Fly Trap? Uhhh, YIKES!
Ahem. I've seen this (well, in the previous pic, with edge-water) on my seedlings awaiting
being planted out; At that time it is 'cOOl'.

Tom K has a great theory about it on the previous page.

Perhaps literally prop up the affected leaves, edges-higher-than-level, rinse them with clean water occasionally, yet leave unaltered and see what happens. Edges of car trunk lids/panels get rusted in the same fashion.

Thanks guys! I appreciate your thoughts on this. I may try that. It is happening on the newer leaves too so it is definitely something but probably nothing major. I did see Toms reply. I have had water droplets in the past on the outer edge of the leaves but I went out there this morning and they were all dry. I will keep an eye on it! I appreciate it!
