Nitrogen toxicity in early flowering

Been a week since i switched and yesterday i fed them a mix of veg and bloom nutes, both in about 1/3rd of recommended dosage, figured they need nitrogen during stretch so i even upped it slightly. A few hours later i noticed that the 2 kushplants had clawing leafs which i hadnt noticed when i fed them but im pretty sure they were already clawed. Was probably too busy looking at the hairs, excited about my first buds :P
One more clue that it has been going on for awhile is that some shoots go basically 90 degrees to the side which ive read can happen with nitrogen toxicity in some strains. Noticed that wierdness a few days ago but thought i overfed them kelp and halfed it this watering.
Anyways, since i noticed it in the middle of the night i could only flush with 10l of water for each of them since my plumbing is "screaching" in the wall. Now the nightcycle is on for 6 more hrs and i dont want to interrupt it to flush them more thoroughly. Or should i?

What i feed them is low doses of veg and bloom nutes with added kelp, humic acid and low doses of calmag. Never been near the lowest recommended dosages so didnt think this would happen.

What temperature is the water you're giving them? I had an idiot friend water one with cold water once, and it clawed real quick.

Well, just wanted to point out that ^^^ read differently could be interpreted as you asking if the OP if he is an idiot. I am sure you meant no ill-will offense, or insult... just sayin' :peace::peace::peace:

How often are you watering? Are you feeding with every watering? What medium are you using? I like to feed low dosages but with every watering rather than high doses occasionally. This helps avoid nutrient burn and as soon as burnt tips are seen just back off a bit on the concentration.

Cold water would not cause clawing. Assuming that n tox is from watering with cold water seems less smart to me than the idiot using cold water(root like it pretty cool, you'd have to be freezing the water to cause problems which would show as purpling not clawing), which isn't actually bad in any way for the plant, to water his crop.

There was hat one guy on here claiming his qp dry colas(lol) got their density from him pouring freezing water on the roots. That's the only time you actually doing something detrimental with cold water. Watering once with freezing water would most likely do absolutely nothing negative to the plant at all.

Lol, I didn't say anything about a toxicity. I just said it could be something different. Like underwatering, or shocking the plant.

Stress can cause clawing in some cases as well as lockout, but cold water would lockout p not n. In 90% of cases with growers that don't know why they're clawing its n tox.

I know that, and agree with you. And it's a process of elimination sometimes. Sometimes it's a few problems rolled up into one.

Definitely true, but almost no chance that clawing in any situation is from cold water.

Okay, lights are back on and i took one of them out to inspect. They seem to have gotten alittle bit better since yesterday, although most of the leafs have clawing to some degree but not almost 90 degrees like yesterday.

About the watering, i feed every watering and i wait until they are dry which takes about 4 days. they absorb a shtload of water every time. They are in 17l (4.5gallons) and its plain soil with perlite. And i do not water with cold water, i keep it around 25-30C. ;) They look pretty healthy and perky but shes alittle bit dark but its a Kings Kush, they are pretty dark in color..

Oh, that bonghit almost made me forget.. :P I water with just alittle bit of runoff, 10% at most, could this be causing some buildup? Maybe should flush them all next watering?

shes actually abit darker irl:

What do you think? Nitrogen or watering?

Probably overwatering. They look a little light to me as far as n goes. You don't really have clawing either. Some slight curling, which suggests overwater. The plant looks good overall though, I wouldn't stress it too much.

It does look like you're having mild ph/tox/lockout/temp issues at the roots and at the top of the plant. As to which of these is causing the problem... I have no idea. But something in your root zone isn't well balanced.

Oh, didnt expect it to be overwatering, as i wait until they are really dry. I hope its nothing too bad going on in the rootzone that will punish me later..
But ive had overwatering before and yea, the droopyness is similar but yesterday the tips of some of the fan leafs had almost a 90 degree claw. Can that really be because of overwatering?

Maybe I'm missing something from the pics. Can you take pics closer to the new growth on your plants?
