4 week auto growing buds can I reverse it back to veg

Automatic cannabis or cannabis bred with any ruderalis is designed to flower by age and not the light cycle. If you change the lighting period it wont make any difference, and may cause hermies from the stress. Best bet is to address the light leak asap and let them do their thing. You cannot take clones or reverse to veg as they will be even older by that time. I suggest you get some photoperiod strains next time and grow a mother to take clones off and keep a perpetual grow going. Photoperiod plants can stay and yes sometimes reverse back to veg as long as the lighting is at least 18/6. I hope this helps!

I don't understand. Autos don't need shorter days to flower, they will start flowing normally between week 3 and 6 depending on strain and conditions? I would be more worried about the photo plants(if they are) in the other tent getting light from the auto tent in their dark time... That is all.

no problem.light color wont change anything.no reversing back to veg. You can even use HPS throughout vegetation,I do. The only difference would be internodal distance,HPS makes it bigger,MH keeps it smaller.But 3 days wont have an effect on them no worries.

So I may have confused some of you. I have them on 18/6 cycle 600watt I had another tent going with plant I The flowering stage(hps yellow) the autos were in direct contact with yellow light cycle for about 3 days before I realized it. These 4 autos are going buds in week4 but I have the same exact stains in week 2 and is not growing like the 4 who autos in direct contact with flowering light cycle

You should be running 18-24 light cycle so not sure how you would be returning autos back into a veg state! They are autos, they will automatically flower when ready, I would check all of your set up and make sure nothing else is causing this issue

Usually an auto will flower no matter what based on its own genetic timeline if the genetics are true, To answer your question directly, if it's truly an auto, you cannot reverse it back to veg. I would watch those plants under a close eye due to the extra light they received to make sure nothing goes bad.

I never had problems with extra light after lights go off with autoflowers. I can't say they won't mind it but I've never got anything bad off it. It mostly depends on the quality of breeding process. If it is from a trusted breeder and already went into flower at week 4, say it's a true auto and you are safe.
