you think it doesnt make sense but it does. its just too well fed. it has n tox because it has dark green leaves with curling tips and the veins of the leaves look like they’re on steroids. thats n tox. this plant is overfed so the feeding should be dialed down. you cannot feed 1:3 grow:bloom. plant will not get enough potassium that way because bio bloom is low on potassium and rich in phosporus. it needs grow to get adequate potassium. just at lower doses. tbh this plant can go at least 2 weeks with straight water. also i’m gonna do you a favor and post a link so you can stop this 1:3 ratio stuff. as you’d see from this chart biobizz suggests using 2:1 grow:bloom to 1:1 during whole flowering in unfertilized medium (light-mix which op uses). thats how these nutrients are designed to be used, the op was just overfeeding with correct ratios. https://www.biobizz.com/wp-content/uploads/2020/03/Nutrient-Schedule-EN-2020.pdf

Man, what you just said, makes NO POXY SENSE. OK, he has an N tox, so you say keep the grow and bloom ratios the same when clearly they aren't meant to be the same. And I have experience with p1000 they aren't N toxs....N toxs don't show up as though something covered it from getting light. It's the light rotate your plants and LST and remove some top fan leafs. You do NOT HAVE N TOX.

N toxic, dial your feeding back to .5ml/l for both grow and bloom. bloom nutes are also very rich in P extremely rich, plants dont need that much P and they do not contain enough K which regulates water intake of the leaves. plus both P and N are antagonists for K. which means when these nutrients are abundant in the soil K uptake will be diminished.

Oh, and for the grow and bloom. You want to do 3:1 ratios. So that means .3 grow to .9 bloom you make up your own ratios but it's normally 3:1 check with your nutrient brand. Good luck.

Haha, we have nearly the exact same set up. I have underwatered my plants so much this time around. If anything its overwatering bro. 1L is too much. Cut it down to 300ml and before you know it you'll be running into underwatering, which your plant bounce back from within hours after watering when they are droopy. So if you watered and they stayed droopy its too much water at once. Overwatering. Your plants are good. I take it you took them pics under natural day light right. As for the leafs. I've had many like that. How I found my way out of it. With that light for some reason you get a lot of that. Let me guess, them leafs were underneath other leafs. It's the light. Anyways how I stopped leafs from going like that was LST and take some fan leafs off from around the top to allow light to reach down below and rotate your plant. They are defs or anything because you can tell that its just parts of the leaf that was covered. Good luck bro
