Edges curing in

[Ambyr]

My veg plants in 3 gallon pots are looking a bit strange with curling happening on the leaf edges. I was about to do a peroxide flush about a week ago but was advised against it, should I be worried? My temp is 75 and my humidity is 55. I have a Loriflux 6 blade veg light and it is super far away. I’ll show photos and only turned up 25 %.

Also, I will note that I accidentally gave these plants nitrogen toxicity from too high of nutrient levels when they were in 1 gallons cause I’m a nubby.

I sprayed them with seaweed right now that’s why they look wet.

Hi Ambyr you have a great area and very nice light. Well you can certaintly recover easy here just use the kelp in the soil don't use it on the plants. It shows signs of heat and needs more air circulating. I'd just water with plain Ph for awhile till these look like they need N if they will at all, they are real healthy green and showing like they will want to flower less than a month to me. When i have issues with ill plants i do what you do....less light and i use epsome salts 1-2 tablespoons in gal. of water let alittle run out bottom. Be careful spraying with light on even low light cause that's a powerful lamp.

So I should water in the seaweed when I feed? I’m hearing a lot about epsome salts, interesting. So when will I do that next time I feed or at any time?

I would do it on the next watering. The kelp helps in the soil to energize the roots helps "uptake" into whole plant relieves heat stress same with epsome salts which flushes soil back into neutral while adding minerals. Even if pots don't feel " light in need of water by lifting" i would run either thru the soil with just alittle bit of run off. Lower the brightness for couple days. That's what i'd do. I wish you well and plants recover, it's a simple fix i think.

So I ended up doing the seaweed flush on Tuesday am. It’s been a few days and the day I did the flush they started to look much better n then ultimately reverted back but they also look like they are growing and lots of nodes popping up. Any suggestions for my next watering tomorrow am?

I was thinking a very light ppm of nutes like 300-400? Plus additives?

Go for it an just give 1/2 recommended dose in the water then if all looks like they love it give full strength as they get older they handle it better
