Stunting after 1 month?

Try raise the RH to above 60 and stay between 70 up until pre flower and lower 50. And give tyour plants some rest time. On the feeds just feed and get her feed in with water+calmag and she should be fine. A N tox will stall your plant. So flush it softly and go and restart her a grow diet. Keep temps between 21-28max 25 is the desired top range but if you have good air flow on your canopy the tem9 is much lower. Also you can try give her a stretch. So, you want to leave the 24hr light thing. As so no plant gets 24hrs and she's getting a steady temp so a rest say for 4-6 hrs should drop the temp enough and you are still in the stage when you mess around with temps in veg that's how you get them to drop. So a 5-8c drop for 4-6hr. Good luck bro.

You've got a major problem with nitrogen toxicity here with her... each strain and each plant is different in terms of what they need/want/can tolerate and she is obviously not tolerating the amount of nitrogen you're giving her. I would do a heavy flush, my friend ... run 3x the water as the pot size - you're growing in 2 gallon pots so you should run 6 gallons of PH'd water through her and let her dry out before doing anything more. I know you've told me before you haven't given any nutes but you didn't mention what kind of soil you've got her in... if it's an enriched soil, it's probably just too "hot" for her... but don't even THINK about transplanting because autos do NOT like to be transplanted, especially at this age. If it IS an enriched soil, I wouldn't give her anything but water for a while - until she "tells" you she needs something more.... certainly don't give her any grow nutes as they have a lot of nitrogen in them.... you MIGHT want to start her on some bloom nutes as long as the nitrogen content is under 1 (preferably 0!) ... but again, my instinct is to wait until she starts crying for something. Good luck and keep fighting! She may surprise you!

I had the same problem years ago, sometimes autos don't need to be trained because it's a stress, you should leave her in peace, and eventually wait 2 weeks for an lst. Sometimes autos are too much fast so it's better to let them grow without human touch :)

bending it over can make it seem like it stalls a bit, but really the previous growth is just more spread out. In some cases it may cause a little too much stress, but if you don't see some oddly shaped leaves, probably okay? if you think the internode length is too short, raise light 2" and see what happens over 7 days or so... or until something becomes apparent. From what i see in pics it'll be more about personal preference as opposed to what is right or wrong -- e.g. i dobt anyone has "optimal" fully mapped out. autos will have quite a bit of variance.. so even if those are all the same strain their is still a good chance in seeing different physical traits.
