Can't seem diagnose this with research. Odd problem possibly.

Okay the run down.

- 3rd week flowering
- fox farm nutes/with solubles every other watering (3-4 days)
- soil ocean forest/pro mix
- Use rain water as much as I can.
- started flush a over week ago when I first noticed it.
- havent watered since but want to today.
- 1000 hps
- good ventilation & temps
- ph to 6.5-6.8 every time. with the vial and drops method.

- plant with issue is about 6' tall its one of two of the same strain (northern lights or Sensi Star.)
-Only one is showing this issue.
- looks healthy, but also seems to have stalled.
- 10 other healthy plants along with it.



Thank you in advance ill check back in later on this evening!

can you give some more info on the issues you are having, with the pics I am having difficulty distinguishing what the issue is/looks like? Are you talking about the clawing leaves?

well the leaf curl looks like nute burn to me, are Fox Farms nutes organic, or mostly organic...I ask because organic - ish ferts curl before burning on most of my strains...then again was the curl part of the original issue, or is it a new one? Could anything be happening with the roots? Like what size pots are they in?

Too much nitrogen also makes growth slow and stop altogether...so...think about it and just maybe it is just overfert...easy to do...hard to fix...all you can do is flush and move on...you have flushed, now you just have to keep watching for things to pick up...

I have one strain that gets curly in flower, no matter how careful I am to not overfert...the only time her leaves are straight is if she is getting no nutes at all...she can handle my mix of soil amendments and have alright growth, but there isn't that wow factor after a little dose of nutes...it is like a OH NO factor...give her anything and she just curls up...continues to be a 2.5 ft plant that yields me around 3 oz avg of super killer smoke, so who cares if she has curly leaves...it doesn't look nice, but it seems to be alright, and I only mess her up worse when I try to fix it...so try to ignore it, unless things start falling off or turning black, or burning or something...lol.

Have you cut back on your nitrogen fertilizer and started adjusting your ratios towards more of a flowering one. Using the same nutrient solution for Veg->Flower can stunt the plant after the plant starts to show flowers.

Well To sum up all these, they're are in about 4 gallons of soil, fox farm is a combination of organic and non. I have been feeding flowering nutes to it only, for 3.5 weeks. Never had this problem before but the new growth is thin and claws down mostly at the top of the plant but can be noticed all over just not as severe. I think nitro toxicity is the problem just dont know how it happened.. Seems to be stunted pretty good. I gave it rain water with cal/mag today, it was feeding day, feed all the rest as normal. I used clearex just over a week ago I see no improvment yet and minimal growth but still very healthy over all. It does how ever have some yellowing fan leaves at the bottom now that I think about it. How can that be?

Thank you guys!

humidity is always been on the low side in this room just basement atmosphere, actually has been lower than it is now though. I also run a large hepa filter in the room so mold is not likely either.

4 gallons of soil? and the plant is 6 ft tall? Sounds like it might be root bound imo... is it drinking a lot of water, but always seem dry?

They dry up at about 3-4 days typically I say typically because it has slowed on water uptake to now that you mention that. However She stays perky reaching for light even now, minus the fan leaves showing this problem. 4 gallons seems like it can support these plants. Do others feel this is a shortage also? Starting to feel like its just taking up real estate under the light. BUMMER..
