Ok guys so I have a 3x3 tent setup under a vivosun vs2000, started these ladies in fox farms Happy Frog surrounded by FFOF. 5 days in a greenhouse outside before ohio weather decided to be ohio weather and I brought them in lol. 20 days inside now temps are staying from 72-75 and RH right around 50%. The 2 in black pots are RQS Do Si Dos autos and the other 2 are RQS OG kush Photo fem. Mostly all of them are getting lighter/darker veins in the leaves and obviously one has tons of yellowing. What do you guys think my problems/deficiencies might be? Any and all help would be really appreciated!
Just looking for a little help here

Just figured I'd come back and give a little update. The one with the yellowing continued to get worse. Fed them all some fox farms grow big.1/3 strength and the watering after that they all got CalMag. the 3 seem to be loving it and the last one continued to struggle and has actually started flowering. I'm figuring since that ones an auto the stress made it start. Lol live and learn I guess

well it's been about a month and the smallest one that struggled real hard still hasn't stopped lol...I'm at a loss trying to figure it out at thos point other than it could be light stress. The ones most affected are the autoflowers. Anybody got any ideas now that I'm this far in?"Light stress"- the plant that's having issues the plant that's furthest from the light by a relatively long way. The other plants, which are much closer to the light, aren't showing any signs of excess light so there's no particular reason to think that "right front" is getting too much light.
Light intensity from a grow light falls of very quickly. The top of that plant looks to be at least a foot below the plant in the back right.
In future, squat down/kneel down and take a few pictures that show the "front view" of the grow rather than the high angle "plan view". That helps readers get a sense of how tall the plants are.
Right front is in pretty rough shape but right rear looks to be overwatered and have a significant nutrient imbalance. Left rear…yeah, they're all having issues.
Best advice is to provide information about the grow. Age of the plants, watering practices, nutrient brand and EC, what pH are you seeing (if that's a soil thing), temperature, humidity, light hang height and dimmer setting, wind speed/fans, etc. The more the better and the sooner the better.
Right front is getting its ass seriously kicked and it's not "it's an auto". I've grown autos and photos and either type will grow to > 4' when they're well tended to (and autos are f'in beasts, frankly).
What's interesting is that each plant is showing a different type and/or level of distress. Just a WAG from a hydro grower but it looks like right front could be in a different type of soil than the others.
One thing that really mucks up soil grows is when improper watering results in the soil being hygrophobic//some parts of the soil get hard enough so that they can't absorb water.
Post more info and better (bigger) photos and someone who knows soil should be able to help turn things around.
Thanks I definitely appreciate the input! The one that's been struggling real bad is alot lower than the others because I was starting to think maybe light stress and took it off the stand I had to keep the canopy more even. I think what you said about soil becoming hygrophobic can absolutely be part of if not the whole issue. Trying so hard not to overwater I probably didn't water enough and caused that lol.
I appreciate that. I can be, shall we say, "not shy about offering advice" but I don't mean to offend.
Understood.
Light levels ("PPFD" which is akin to how fast rain is falling and is measured in micro moles per square meter per second but I use µmol because I'm a Mac snob.
) drop really quickly. If PPFD is, say, 500µmol at 14" from the light, it will be < 400 at 10" from the light. Dollars to doughnuts, Right Front is hurting for light.
Watering takes practice from what I can gather. I drown my roots (hydro) so I've got it easy.
I don't know how to check to see if soil is hygrophobic and it might be that you can't do anything about it (that wouldn't surprise me, frankly).
You're doing a lot of things right because the Left Front and Left Rear are looking good. It's the Rightside Guys that need some attention. Right Rear does look like overwatering (so sayeth the guy who drowns his roots) so the drooping leaves should be clearing up soon.
I'd have expected to see some other growers poke their nose in here. How about posting something in the "Marijuana Plant Problems" forum? Just a thought.
Yeh, if you're going to do that, get some current photos. That will help.
