Curl and clawing,N-Toxicity?Flushing?
SuperGreenGoblinstarted grow question a month 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

Leaf Tip DiscolorationAre the tips of my plants looking normal? I had a random comment from someone that I may be going overboard on my nutrients - the very tips of my plants are turning white-ish neon green and I am wondering if this is due to the plants natural process in flower? Can I correct?

Nitrogen toxicity ?Hello,I think I have a nitrogen excess, but I never had before.I see those tips going down, but leaf itself is quite good, except for this darker green. Leaf is not so dark, I've seen pictures on internet darker...but on 3 plants, this is the only one with this problem.

Harvest Time?2Stunted Autoflowers
Top Cola seems ready, though lower bud sites are still underdeveloped.
Seems there's lots of amber, though maybe still cloudy.
Should I wait until the lower buds develop and risk degraded THC, or harvest now?
Any help would be great, Thanks

Curl downHello growers, I have a problem that has been bothering me for a long time, when I water the plant it always wilts like this, but the next day it is fine again. I am worried about whether it does not cause my problems, what bothers me that the plants then grow badly.

How to tell from light burn vs nute burn?Some of the tips of my leaves are turning yellow/white. This is only on the top leaves. I would guess this is from light burning the leaves and not nute burn since all of the lower leaves are not showing anything like it.

Yellowing/brown tips of top leaves. Heat-burn, light-burn or both?Top leaf tips turned yellowish, brown with curling. I'm leaning towards light burn as the cause, but noticed it started occurring during the recent hot weather. I've raised the lights, but am wondering if this could actually be related to the heat.

Heat stress, nute burn and light stress?It was very hot in the past week with temperatures reaching 32°C in the tent. I was worried about heat stress. This week I’ve been more careful about the light height since the plants are still growing upwards, but there is a big heat wave next week in my area.

What's wrong with my lemon cbd auto? more info in descriptionThis week something is wrong with the Lemon CBD auto. Might be because of under/over watered (only watering every couple of days, when the pot feels light) or nutrient burn... Can't really reach a conclusion but might try to water ph'ed water for a while to see what happens

Overwater?Over watered these girls somewhat. Although the pots are dry and very light when I do water. I think I have given too much at a time. Also about 2/3 hours before lights out they drop like I have never seen before. These pics are 12 hours after light on. First time in 16ltr pot
