All the time, just the top growth though.

Lights maybe?
My suspicion is that you have some sort of environmental issue - ultra-low humidity, too hot, too much light, perhaps no air movement or a ventilation problem. I'd also avoid putting your plants through severe dry/wet cycles right now. Heck, some grow mediums when dry on top are just as dry in the middle and bottom because they wick water so well.

Yeah man, thats something in your environment. You got a fan that blows around in there and one changing the air in the room?

yeah I have a 24” tall oscillating tower fan, Maybe I need a clip on 6” around the top of the canopy ? Because my fan only covers the bottom half I guess. I also have a 6” inline with carbon filter running 24/7. My humidity is 42ish most of the time. And mid 70’s for temp

love this analogy ^^^ thanks a lot! I ordered some! Fingers crossed!

Hey folks. So here’s an update a couple days later, I have been watering when pots are light and my moisture meter says dry which has been about every 2 days. I have since elevated my oscillating tower fan on some buckets so air is blown over the entire height of the plants (gently) and I added another fan on the bottom to blow around the base of the pots.
There should be plenty of air flow and my 6” inline exhaust runs 24/7.
temps are steady about 70 during dark periods and 75-79 during lights on. RH stays about 45-50 %.
I top dressed a tablespoon per gallon of this tomato food because it was the only organic one I could find locally. It’s only ingredients are dehydrated chicken shit and bone meal. I mixed It in the top layer, mulched with straw and watered it in following these pics.
My tap water is very hard- about 550ppm so I have been using RODI water pure H20, with <10ppm
quick tangent about my water:
-when I just process the RODI, I get a reading of about 5 ph, if I leave it out for 24 hours, I get a reading of around 8... I don’t know the reason for sure. I have read many theories about the H20 grabbing carbon dioxide molecules and becoming acidic... I’ve also read that because there are no minerals in RODI water, that the meters can’t get accurate readings so disregard what they say... but they are consistent every time I fill a bucket... so I’ve been leaving it for a day or a couple days and ph’ing down using blackstrap molasses until I read 6.5 for safety
Buds are starting to form up nicely in week 2, but I still don’t know why the top leaves are sad all the time. I notice on a couple spots the outer rim of some fan leaves are lighter green.
thanks for following guys and thanks for all the help. These things would be long dead without this site LOL.

Just restocked Tuesday with 4 bags 2 cu ft Back To Nature Cotton Burr Compost. A couple 3 year old bags got me through the Pandemic. 4 cubic feet bag of perlite and 3.8 cu ft bale of Pro Moss made my day. $98 for all.
Actually, just stopped in to highly recommend Back To Nature Cotton Burr Compost. Been using indoors and out for 12 years. Contrary to what it says on the bag, it is awesome in containers.

Inline RV water filter. I have hard city water. Comes out 7 ph. but its got lots of crap in it. really gunks up my sprayers. So i got a couple of inline RV filters and now my misters stay clean. Those should filter enough for your plants from you hard water. And as long as you limed your soil mix correctly then you should be fine using tap water.

do you think the RODI water is a problem?
Here are some pics from right now. I don’t know what else to do to fix this. Nitrogen toxicity? That’s the only thing I’ve read that looks similar, but I don’t know how that would be the case.

I'm no expert, but if my leaves looked like that the first thing I'd adjust is my lights. Those LEDs might be too close even though the temps are fine.

i also forgot to mention that I also did that! Pulled them up about 18” from the tops
perhaps it will take some time to correct. It’s been about 36 hours

I just set up my rain barrels actually after the winter with plans to do that. I have only been using RODI <10ppm water so I’m wondering if anything, am I low on certain nutrients that would normally be abundant in a municipal water supply. Like everything I tend to over analyze. I mixed half RODI and half tap water so there’s some of those trace elements needed. Let’s see if that changes anything lol,

Does vermi actually add usable silicates?

Yep. Dr Bruce Bugbee uses it in his mixes for this very reason.

There is a prevailing consensus that 75 °F is the ideal ambient temperature to grow Cannabis under HPS lighting without CO2 supplementation. This experimental result indicates that an 84 °F ambient air temperature is required to achieve the same optimal leaf surface temperatures when using plant-optimized LED lighting-- and that a 75 °F ambient air temperature with LED lighting would not achieve optimal leaf surface temperatures, slowing metabolic rates and leaf and flower production.
