Anyone know what’s going on here

Plants were all cruising along nicely until the last week and half or so I noticed 5 of 16 plants having light leaf edges that eventually turn yellow while working it’s way in to the center of the leaf. Seems to be a bottom up issue but one of the plants has had this start from the top down. This is a mix I’m very familiar with and haven’t seen this issue before. I almost want to blame the led for some reason cause I’ve had some issues that I didn’t use to have since switching to them last round. Usually nitrogen or Calcium deficiency is first to show up in this mix and any excess that shows is always too much nitrogen if anything. This yellow leaf edges business is new to me. Pics are various stages of the yellowing in different plants. You can see on the one it’s a top down issue and on another it’s a bottom up issue but same leaf symptom. Promix with castings and lime added. RO water. Low strength epsoma dry fert was mixed in upon transplanting. I did top dress with some more after the first watering which I don’t usually do. I am seeing nitrogen deficiency start on two plants that aren’t pictured so it made me think this wasn’t a problem of excess of something in other pots. I’m stumpedE6587A60-9C6F-4C70-89BA-26B476D8DE03.jpegB05C3819-DA88-4015-96FC-727F1445DEE7.jpegE6587A60-9C6F-4C70-89BA-26B476D8DE03.jpegB05C3819-DA88-4015-96FC-727F1445DEE7.jpeg

It’s not lights.
Since it’s flowering I’m thinking either PH, or nute def.

Well I don’t ph anything. Haven’t in years since using lime and never had an issue that couldn’t be resolved. Simple to fix Deficiencies have been the only issues in years. Perhaps ph idk. Wondering about potassium. Also the floor has been colder and I just noticed it today walking barefoot. Doubt that’s a factor in this but gonna get them off the bare floor

Definitely get em off the floor.
I keep mine on metal shelving.
The reason I say it’s not light is the variation.
Lights affect the tops.
Usually PH or some kind of lockout is the culprit when nothing else makes sense.
Especially in flower.

As a test I’m gonna transplant a few of them late. I’ll put one in promix and castings with lime and no fertilizer. Another I’ll transplant into same mix with fertilizer. I have pots that are just slightly larger that I’ll use since the root growth is significant slowed in flower but they do still spread. Another one I’ll just flush. The other two will also stay in same pot with one being fed and one straight water. I like to try a variety of things to help me narrow fown the issue. It’s the long route. I know. I May have to go get a good ph reader

I do think I used a decent bit more fert than usual which is why deficiency is hard to accept. Maybe ph is causing some weirdness I’ve never seen. I know I don’t let my soil sit after mixing it and perhaps the fert breaking down is causing a ph swing since it’s a larger amount than normal. Another possibility is I did use a small amount of well water on some plants a while back. Can’t remember if this started soon after or not and can’t remember how many plants I used it on. Very eggy high sulfur water. Ran out of RO and did an emergency drink for some of them

Could be man.
Could be a pocket of something overwhelming the plant.
It’s happened in my yard with shrubs.
Also …
If you’re gonna grow in ProMix it’s a good idea to get a Bluepen or something.
You may not need it often but it’s good to have.

Yea I should get one. I really like being a minimalist and used to joke about being the plant whisperer who just grew by looks and vibes. Lol. Another possible culprit I just thought of is well water. A while back I did give a small emergency drink to some Plants but can’t remember how many plants or how long after that the issue showed itself. Very sulfury egg smelling water.

After looking at all your pics and hearing you added lime. My thinking is it's Ca toxicity from the lime that's locking out K. Because that looks like K deficiency to me.

I always add lime but perhaps I added more than usual. I’ve been sleeping very little the last few months and have caught myself almost making silly mistakes so I won’t rule it out. I’m really hoping it’s a deficiency and not due to lockout. I’ll find out soon after I try a few things. Really sucks this has to happen in flower. Hate new problems I haven’t seen in my garden before

It's worse in some pots. Some look fine. Is there a chance you gave some more lime than others?

If you think it's lockout from too much Ca you could try flushing them a little. I add a little citric acid when I'm trying to flush out excess Ca. I don't go crazy though. Just a little citric to make it around 70. I add 1/16 tsp per gal to my 7.8 well water when I do it. It doesn't take much. And I try not to get a ton of runoff, since I'm doing organics and don't want to flush out all my nutrients.

Whatever you do, I'd take it slow. And only do one thing at a time.

I’m pretty sure I gave them all a tablespoon per gallon of soil. Now where I’m sure there was variation was in the fertilizer I added. Small variations but some probably more than others. The fertilizer also has calcium in it though. I used more fertilizer than usual this time for all plants though. It’s just some dry epsoma stuff. It’s pretty good stuff actually.. The plants that are effected the most still look lively with affected leaves praying even.

That could do it for sure. Whatever you do, don't feed them for awhile.

Well water may also be a factor as I used some for some plants a while back. Just can’t remember how many plants and how long before the issues popped up
