In the last 2 pics from this week you can see #1 leaves "tacoing" I've read this indicates heat stress, but the lights are over a foot above, great airflow and surface temp is only 78°. What's the deal? @hso do these girls like cool climates??

Hey man, just here with some unsolicited advice , just ignore it if it's not welcome 😅 looks like the very start of magnesium deficiency: you can tell by the yellowing between the veins of the leafs - add calmag to the feed or as a foliar spray two times a week the issue should stop spreading. Basically Mg related issues are pretty common when you mess with the lights ... Hope this helps ! 🚀

Lights should be 4 feet away. Have a look at the distance of the lights in a Cannabis Facility. Cheers

@Elysian_gardens710 Hi mate I think your root system could be undergoing some stress Maybe from a combination of a little overwatering and heat. Hydrogen peroxide 30% is your friend simply add 5mls to 5 litres of water and pour thru the pot next watering This will kill any nasty pathogens and add extra Oxygen to your roots Hope this answers your question and good luck

Most likely a root problem. Because these pots don't breath as well as fabric pot it's possible if you've overwatered to have leaves curl just like heat stress. It's best if your PH is lower in the 5.8-6.2 range.
