They look great under their scrog. You might just reevaluate your light level. It might be a touch low judging by some possible stretching in your “before” pictures.
When i got them they were alrdy stretched in the solo cup. Since ive had them theyve been under a mars hydro uogradded 2022 tsw 2000 at 12 inches. I had them for 30 days from the solo cup pics ( day i brought them home from friends who neglected them ) til now when i put into flower.
So i can keep temps and humidity where i want them bas. I grew in 77 degrees and about 65 pergecnt humidity and than dropoed hunidity gradually to 50 now since entered flowering. Temps are now avergaed at 75.
But alot of the vpd states to flower in like 72 degress and 60 humidty. Wondering what is a good temo n hunidity combo for flower?
I ph my water to about 6.3. Give of take .2. Run off is usually about 6. And i havnt done ppm etc yet or tds but am learning to start that. I also give nutes. Than water. Tha. Nutes etc. Wond if can give nutes. Than 2 water cycles because they dry out fast. 2 days basically need more
If you hit the VPD it will help your grow. But like @ShockDog was saying, this is something that you’ll probably struggle to maintain and to what gain, who knows. My last grow was all over the place on the heat and humidity and I still had a great harvest. Like blow my mind harvest without ever getting the VPD right. Not saying I don’t try, it’s just not easily done in my current setup.
Here here. I feel like after you get a few grows under your belt you can set to work on refining you process (which you will do anyway). Until then, just grow some weed. You will be amazed by the fruits of your labor. Guaranteed.
Awesome. Ty for responding guys. Makes me feel better. So I’ve been on point with tenos between 74 n 78 during day. And 66 to 70 at night. And humidity I’ve controlled down from 70 to 50 currently. Temps are about 74. 75. Now during day and 50 to 55 hunidity max. Nights about 68 to 70 still
You’ll be fine as a frogs hair if you keep this up!
It definitely looks like overwatering… Now, because you have only watered once and it is three weeks old MAY seem like it couldn’t possibly be overwatered BUT. Due to the size of your container (pot? bag? I am guessing pot) the one time that you did water saturated the soil and the soil has STAYED saturated because of the pot size/root size ratio. There’s nowhere for that water to go. Pick up the pot. If it feels heavy, then you know there’s still a ton of water in there that your little plant can’t possibly drink up and then experience it’s necessary dry period. Dry periods are equally as important as watering times. If they don’t get a dry period it’s the same as if you are watering them every single day… Overwatered.
I faced the same difficulties in the beginning and now I start my plants in a suitable size pot or even solo cup and wait until they have a respectable root ball before I transplant them into something larger… But even then you want to make sure your container is an appropriate sized container otherwise you will end up experiencing this same type or problem all over again.
That way they get a nice dry period and that root system is forced to grow outward SEARCHING for moisture and water which ultimately benefits the plant.
Thanks bro. Can we just exchange emails or something 
?
It’s a 3 gallon pot and I did put about a gallon of water through it. I was getting antsy.
It’s an auto and everything I’ve seen says to not transplant autos.
Bro. It was THIS REASON RIGHT HERE that I screwed up and overwatered so many autos. Same, bro. But they can be transplanted. Very very carefully not to shake them up too much. But I have found that information you read EVERYWHERE to be misinformation. And yeah, dude. We could exchange emails but I just got in trouble for doing that very thing and I am trying to stay within the lines now. the ILGM forum frowns on it. Has to do with maintaining anonymity for their customers or something. I am available on here though. 
I’m just lucky they let me get away with using curse words as often as I do.
It’s a hard habit to break. 
Yo, Deep. Congrats on the Member of the Month, dog. Respect. 
Thank you, brother,
Ah, okay! So it really is just trial and error based learning. Hopefully this chat will help cut my learning curve. I’ve been able to grow pretty much every fruit and vegetable one can think of but a weed, of all things, is giving me issues.
That sucks that I can’t connect with you off site. I feel like I need access to you 24/7 
.
The soil is dried up but I’m going to wait a day or two and water it lightly. Thanks for the tips.
