Can't really identify the problem - K-Train 1st week of Flowering

Hello guys,

Thank's always for the time and the help you provide for people on this forum,

So I got this 2 months old K-Train that just started her flowering period about a week ago.
It's in a mixed soil, growing outdoor and about 1,2 meter (4 feet) tall, I have been giving her nutes with 6-2-3 NPK, and I have stopped feeding her for more than 4 weeks (water only).
These curls she has been showing have just started in a couple of branches at first, but quickly took a larger dimension, it's been upsetting me and I don't wanna take any step before I make sure it's the right thing to do.





I just hope it's not a big deal.. thank you guys again for the help ! Cheers !!

How often are you watering? The leaves look like they're just very heavy and curled down. That's normally from over watering.

I water once every 2 days.. cause it's very hot in here, and the soil dries very fast.
I just hope it's only overwatering.. and not something else. In that case, I can take the watering down a bit.
It's not just that, some leaves on the bottom are turning yellow, then brown, and fall down eventually :/ :/

Thanks mate

It's most likely a nitrogen toxicity. I don't think the leaves will straighten out again. That's what they call the "claw"

what does the new growth look like, If the leaves are flat then it is coming out of it and water when they need it use a meter if it's hot they will take more water.

Thank's guys !
I thought it might be Nitrogen Tox too, damn !
The new growth is curled up in some branches, and flat in some others, and since it's already into flowering, pistils have started coming in and
covering the tops..

There is still one remaining issue I don't quite understand. I haven't been giving nutrients for nearly a month now, and the curl ups started worsen until lately. I thought that maybe the soil contained a huge amount of Nitrogen already (even if this supposition is less likely to be true).. that's when I started flushing and watering with tap water only .

I think a point you're missing is that once a plant is subjected to huge amounts of nitrogen and the leaves curl like that, they are NEVER going to uncurl. Your new growth should be back to normal as the nitrogen gets used up and lowers back down to normal levels. So what you should have witnessed at this point is:

• Leaves are dark green and curl up rather badly.
• You start flushing and not adding any more nitrogen.
• New growth starts to look a little better, but still curls a bit.
• Another week or so goes by.
• New growth looks a bit lighter like it did before the nitrogen overdose and the shape appears back to normal.

Once you get back to the last half of that, then you're OK. At that point, you'll want to move away from nitrogen heavy nutrients as the plant will not need as much nitrogen in flowering stage.

Actually, no dark leaves on the plant.. that makes me question if it's really a nitrogen toxicity.. the curl ups are a first sign.. but as I said.. for more than 4 weeks now, I didn't give any nutes and the situation has worsen just in the past 2 weeks.

I totally misunderstood what you were saying then. My apologies. I was just looking at your images and the lower leaves look considerably darker than the upper leaves and more curled, which points directly too nitrogen poisoning/overdose.

If you haven't added anything in 4 weeks and new growth is still curling up, then there's something else going on entirely.

Have the same problem week 1 of flowering , flushed today and gave them half nut , how does this affect the buds was that the correct thing to do ?

The last thing on earth you want to do after a flush is add more nutrients. The whole idea of flushing is to get rid of the overabundance of nutrients that are hurting the plants. You're just putting it right back where you started from.

When you flush, LEAVE IT FLUSHED. Let the plant take in ONLY water for a few days and "flush" itself out.

Imagine you've drank too much whiskey. So a friend sticks his finger down your throat, helps you gag out what's in your stomach, then gives you another glass of whiskey.

Water would be better, yes?

The dreadful claw.......Here is one similar that i've been trying to nurse back to healthy growth. 8 days into flower and I flushed it a coupe days ago. Working on PH adjustment now, hopefully she will come back around and i will see some new support leafs appearing soon amidst them nugs. Any other suggestions guys?

Don't let the high temps dry the soil quicker then the plant can uptake the water or you will be left with a salty medium which will feed every watering. Either feed less with every watering with run-off or drop temps accordingly.

Hmmmm...am I the only one who saw this? She has been given no food at all for 4 weeks? The plant is starving...and needs nourishment. Apparently the medium(s) you have her in is/are nitrogen rich...there is an N issue there certainly. But that is not the entirety of the issue here. With N toxicity the leaves turn very green indeed... However, the leaves will also have a 'plastic plant' look to them. These leaves look like they have a 'papery' appearance...and likely feel like very fine course sand paper. Flushing will certainly not fix this problem the plant needs to eat.

All this is of course merely my opinion...get others, do some research and make your own choice.

Looks like mold or mildew on the leaves

Thanks TacoMa did a lot of reading on here before I posted there's people saying flush with half nut , This I didn't understand as u said I think I added to the problem , i was ready to chandler from green dream 1 grow to my flowering nut , so I added 1 tea spoon full to 30lts of water that was around half what it should have been , I stop this now and go back to Watter think its to late for one of them , I'll get a few pict with the lights off see what u think , only second grow first using auto pot , gutted had the full 2m x 1.2m tent totally coverd with the scrog all looking good , put it down to the learning curve me

A great many people make a great lot of fuss over nutrients. It's almost taken on a state more akin to voodoo than anything else. Plants aren't rocket science. They're just like us: when they're hungry, feed them. When they're not, don't. If they're thirsty, give them a drink. If they're not, don't.

A lot of this in-between, combo feed, mumbo-jumbo is exactly that: mumbo-jumbo.
