Slow growing autoultimate with curled edges of leafs

[Royster213]

Ok thanks man I'm getting on it now. My fans are not directly on them, I do know better than to do that. I still have a lot to learn from AFN and I'm trying to be an auto pro anyway I have a ph tester but it hasn't been calibrated in a while have to get 7&4 buffer tomorrow. U said I need an rh tester not sure what that is or did u mean ph sorry I been working 18 hrs a day kinda out of it just burned one to didn't help any lol. Also getting hum. and temperature combo tomorrow as well then see about needing the humidifier. Trying to do everything and sleep within 6 hours is kinda hard but got my old lady learning to care for them. Just have to wait n see. Thanks again bro. I will keep posted. Any help is greatly appreciated.

Rh is room humidity your on top of it if your getting the combo

Roy-- edge curling is usually an environmental thing, but not always,.. root troubles and allegedly, certain deficiencies,... First, has the curling continued, or stopped? ..looks like your temp's are OK, but the relative humidity is an known for now,.. like A-Train says, any combination of higher temps, low RH and strong air movement can lead to water/transpiration stress, for which leaf curling is a common symptom,... Also, the intensity of the lights, closeness can create hot zones on the leaves, even if the ambient temp is OK,...
... AT means an RH gauge, which you have on the way, or is there now? let us know what it reads for high and low over 24h period,...
...Oh yes, pH meters need frequent calibration, and proper cleaning and storage solutions, or they lose accuracy ...pH testing is a pain in the ass using the accuracy-dubious run-off method, but it'll do in a pinch if done just right; here's a link to a decent protocol--> https://www.autoflower.org/threads/...-testing-and-ph-estimation.41733/#post-928975
... your best choice is a direct soil measurement with a soil pH probe; Accurate 8 makes a good one for the money, plenty accurate if used properly, and far less expensive than the pro-grade meters (200+bucks)...

A-Train,you didn't win all those BOM's for being a newbie you surely qualify as expert.I can't remember if you said you transplanted them into there pot but if you did you could have stunted it.If you haven't given nutes yet it's got to be something in your soil or you just got a bad seed.Try a very light feeding of nitrogen and make sure your entire pot is watered.Also check your soil for any critters and also the leaves.If nothing happens in a week or so she just might have something wrong with in her genes.

No I did not transplant, rh is between 40 & 55%. Checked the dirt and leafs with 60x magnifier, nothing on or in it. Gave a light feed.

So I switched them around I put them upstairs under 250 watt cfl,where I did my first 2 1/2 auto grows never had any temp or rh problems. I'm leaning towards it just being a bunk seed. If she doesn't pick up the pace by the time she preflowers I'm just going to put her in with the photos or leave her under the cfls and try again for that 200+gram autoultimate. I can't find any pictures of a plant with the same thing wrong with it as mine I see nothing like it anywhere. Looked at thousands of plant pictures.

Just goes to prove each grower growing the same strain is so much different still.

I know right. I planned on having this big giant plant by now going by grow journal's I have seen and it's not going as planned. I have my photos for guaranteed meds so I'm not sol. Just going to suck it up n start over

 

[Autonugs]

Key is to be consistent and keep learning as you go....

 

[Royster213]

Right on. It hard because I'm juggling photos and autos. Was hoping to keep my mother bomb big bomb in with my auto under the 600hps,was trying to get a beastly autoultimate and bud my other photos under the cfl just to have some kind of meds. So I switched everything all up n they are looking yellow bottom leafs are yellowing and dying the new top leafs are starting to yellow. I know they moved the photo thread but just throwing it out there guys really need some help with this afraid I'm not going to fix it in time 2 weeks in bud can post pics if needed
