Why is my baby curling like this??

Third week into flowering and one of my babies doesn't seem very happy about something. What is she wanting / lacking??



Thanks in advance!

What are the temps like? What lights are you using? What pots are you using? Tell us a bit about the plants and try to get some whole plant shots, a few with the containers they're in, and maybe closeups of the worst leaves.

I'll put another vote in for "heat stress", because it looks really likely. Have you changed anything about your setup, that could've raised temps, or light intensity, recently?

I am going through a very similar thing now. I know its not the lighting or heat, as I am consistently 24" from the tops. I am now flooding twice a day at week 4 veg in rockwool for 10 minutes at a time. I am ruling out overwatering as everyone seems to say water at least twice a day.

Now I personally am wondering if its a fert. problem. Im using 3 part AN and topping of the res. every day with water only and PHing for 1 week at a time. I am not adding any nutes.

Have you changed the way you feed / fertilize at all? Our plants do look surprisingly similar, The curling and twisting that is.

Ideas come to mind && I vote Heat Stress

maybe root bound?

im going to say nitrogen toxicity. too much nitrogen.

i would vote on a nute problem. seems like it could be turned around quickly.

Do you check your ppm and ph?

If it's not heat stress, my second guess would be low PH. I had something similar happen once(soil grow), when I switched to a new fert, and never checked the PH. It wasn't exactly the same,(not quite as severe) but those burnt/dead leaf edges, curling in on themselves, were there. Strangely enough, it was the 3rd week of flowering, as well. Hmmm.....

The sparse, lanky growth points to a more basic growing variable being off such as heat, light, etc. There appear to be yellowing margins and whatnot but it's second to a bigger and more general problem.

ok soo i have two plants tht look similiar to the "eagles claw" look. my others are fine...SO i feed them the same,temps are good mostly..soooooo im a lil stumpd myself

im thinkin about flushing the two,i transplantd mine and could have shockd em

all these people say different things..u could never really 100% knw..

So I have 5 plants - in 2 gallon pots - soil - each is a different strain - I water them every two or three days depending on how dry the soil is. I run a 600watt light. I put 15ml of Bloom 2-3-5 in a gallon, PH it, then split the 1 gallon between the 5 girls. Its possible heat is doing it, the lamp was getting a little close and for safe measure I raised it up last night. The tops of the other 4 are pretty close to the same heighth, but who knows...this strain (cloud 9) may be a little more sensitive to the warmth? The plant is definitely a little lighter green, not exactly yellow but not as dark as the other girls. This is first grow, so all advice is appreciated. I also flushed all of them on Saturday, so lets see if the nutes were a problem.

Thoughts? When you ask PPM - does this apply to soil grows or only hydro? What is a good range of PPM? What would you think PPM would be of the 2-3-5 I used above in 1 gallon?

Are you using ventilation fans? You look a little high in nitro.

Yes, I have an 8in vortex fan sucking out - negative pressure - passive intake to outside the house - room is prett much sealed tight.

You need to create positive pressure in your op. Nitrogen desipitates faster in negetive air pressure and can cause your plants to get a nitro burn. Change the fan around, or something. You require intake and exhuast ports for proper ventilation.

Bird, thanks for the post.

Seems like if I have more air being forced in than being sucked out, some of the smell will leak out...and I need to have no smell if possible. So you think I need more air coming in than out? Or should I force just a little less air in than being sucked out? To be honest, the fan sucking out is sucking pretty hard - I doubt air sits in the room very long before new comes in....

Im thinking two things - nutrients were strong and the plant burned - plus heat stress...

I have made the error of only having an exhaust fan. Even if you can create equal pressure in the room with an intake fan and an exhaust fan. I'm sorry for being insensitive but I grow where very few people frequent so I don't worry about the smell, I kinda like the smell. I have several venting configurations, it depends on the season. Your right on both counts.
