I’m assuming nutrient burn perhaps?

As the title, I’m having a strange appearance on my leaves. I did some research and I can’t pin point it to what it is. My only belief is that it’s either light burn or nutrient burn; and even light burn is hard to believe because my lights are turned down a lot. It’s a dwc grow, ph is 5.8-6.0, temps are fine, ppm just checked at 1100 and that’s after adding two gallons of ph’d ro water, lights are 2x240 watt led but turned down pretty far. I’m aware the ends of the leaves are burned but that was due to my negligence last week letting the water get too low and ppm too high. So any thoughts?

Looks like Nute burn to me. I would run them on plain PHed water for 2-5 days or until you see the first signs of any deficiency. I’m in Arizona so I’m constantly fighting low humidity and high temps but I run my dwc buckets at 325 ppm even through peak flower.

Too much nitrogen, leaves are clawing

Yeah I’m assuming probably just overt burn, but definitely nitrogen tox. I forgot I heavily defoliated Friday and did a res change on Sunday but I didn’t alter my nutrient level forgetting how much I removed from the plants. So it only makes sense that the plant couldn’t withstand the level of nutrients when half was removed, I’ve removed about 7 gallons of nutrient water and replaced with ro water with a little cal mag

bring ppm down half if not more.

Oh yeah, it started just under 1200, after removing and replacing 6 gallons I’m around upper 800 now; gonna recheck today and reevaluate the need for more dilution. I didn’t wanna shock it too much.

it's a flowering plant I wouldn't go past 900 IMHO unless u know it's going thru all the food u gave it. right now it prob all will want is something with pk. i wouldn't feed it for a bit and if it looks hungry for pk ill give it a little feed of just pk. my feed for the stage your at I would do a 1-3-2 / 1-4-3
N-P-K.

Yeah, I’ve been using charts online because I’ve been too lazy to build one myself, but I feel like it would be the more beneficial thing to do for the plant and my wallet. I feel like nitrogen I need to drip like crazy like you said because my one plant has been so sensitive to nitrogen it’s almost insanity even when in vegetation it was. Do you use genera hydroponic? If so what’s your ratio per gallon?

I use the GH 3 part. I made my own little chart I just need to work out some ratios and do some little info additions onto it. what I would do in your situation. I do use ro so keep that in mind. what are u using exactly right now because I don't use the gh feed recipe I use bloom.micro,Map,calimagic,armorsi

I use ro water as well, I learned early on that tap wasn’t gonna cut it. And I use the same line up with same nutrients, but I also have liquid kool bloom as well for a bloom booster. I think I tried their recipe once, and I totally burned seedlings that same day.

In hydro I always mix 10% ish less of the N part.

seedlings I would use 5ml of CaliMagic, 7ml of FloraBloom, 5 Ml of FloraMicro, a gram of Map. I personally don't like kool bloom other people like it me personally I can care less for it just because its all the same. I want to control all npk values that go in really. this should bring u to 550 ppm around it at least.
