Curl and clawing,N-Toxicity?Flushing?
SuperGreenGoblinstarted grow question 8 months ago
Hello Growers!
Last week I gave around 1ml/L BioGrow in 600ml water. Now all leaves seem to me dark green. Some are disformed/wavey and show burned leave edges and slighty burned Tipps. Two of them seem to be handling the high nitrogen. But the third is curling/clawing. Wdyt?

How does the main stem feel? I see some wilting. Generally, wilting is due to OVER or UNDER watering. Nitrogen is a mobile Nutrient and a little bit goes a long way. N toxicity is possible, but not likely because most fertilizers only put a small amount in. As it doesn't take much for a N deficient plant to get it back to proper Nitrogen levels in one or two feedings only.
I would advise against flushing at this point in time. I would perhaps do a dry-back and let your soil dry out for a few days, then water slowly until run off. Post a follow up in a week and i'm sure all will be fine. It is possible that your plant got stressed as well, but marijuana is very resilient.

i feel like Nutrients never dissolve perfectly if you mix them into water, so there are spots with higher concentration. I always use half the amount to avoid problems with that. Around 0.5ml/l i would take in your case

Firstly, with nitrogen deficiency leaves are clawing differently - whole leaf is flat but tip sharply turns down at almost 90º.
Secondly, "1ml/L BioGrow in 600ml water" Is almost twice of the recommended value for soil - I think leaves distortion is caused by over feeding.
It's difficult to say why only one plant got affected.
Maybe it got more feeding solution,
maybe it has less light than others,
maybe it was a weaker one from the beginning.

I’m with Dabking here. This doesn’t look like a result of nitrogen. looks like wilting. It does look like a watering issue

So Dark Devil is showing some signs of N toxicity as far as I can tell. I have lowered her feeding to 1/3 of recommended, and then she just got plain pH water. When should I introduce nutes again and how much? Also should I flush her thoroughly beforehand?Week 5

I have 2 feeds left before I start the 3 week flush. With the state of the nutrient burn, do you think I should start flush now? Or feed half usual nutes for the last 2 feeds? Her leaves will die anyway during flush so that why I'm not so well worried about the nutrient burn.Week 13

Having some nutrient issues. A few leaves are yellow with brown tips (first couple pics). I also had some nute burn a couple weeks ago after switching to GH so I lowered my feedings. Now I’m confused if it’s an excess or deficiency or something else? Any help much appreciatedWeek 18

2. Barely seen growers using CALiMagic - do you think I should keep it?
3. Any general tips? :)Week 4

I found out my tap water was 9.8. I'm about to water tomorrow with PH adjusted water, I just didn't know whether or not that could be the issue with the tips turning yellow? Bigger plant now too,just not as bad Basically will the soil adjust since it's a premix in between 6.3-6.8Week 3
