Reharvested Scrog grow help

New to the site to see if i can get some opions. Had a nice GDP plant that i harvested a while back that was great! However never cut a Mother of her. I heard of people throwing plants back into veg and regrowing a second harvest. To my surprise it started vegging again withing a week in a half two weeks which sounds like it was a fast transition. So which comes down to the big Question...... What the HELL is happening to the growth stage??? Its topping itself when and wherever it can. The branches are sprouting like mad and a new tree trunk like stem litterally grew around the old one. Here are some pics and can send more. I did only one round of LST which you can see with the strings and never cut or fim anywhere. I kept my bonsai grow style from the previous grow. Once i had the chance i threw a screen on it to set up for scrog. Can anyone explaing why, what i beleive, the revegging the harvested plant created such a vigerous growth on this plant

It has excellent uptake potential and a lot of space to regrow. looks like your bonsai skills paid off. I did bonsai for years until I got divorced, she killed the bonsai trees in transit. The rest died in travel thru texas heat.

Its re vegging, they do crazy shit until they are back fully. I would trim up some of the smaller growth in favor of more main colas and stronger, bigger clones. Beautiful beast.

She looks so strong and you did an amazing wit the scrog. Makes me wanna try re-vegging!

Thanks guys. Have had no problems yet (knock on wood) when she wakes up tonight i will do thee defoliation under the screen. It should have another boost after that. I am wondering about the roots. The first transplant after last harvest i did trim the rootball pretty small but the second transplant was already rootbound like hell. Shes in a 10 gallon bag now and i havnt even flipped to 12/12 yet but i feel the roots are closing in on the edges already lol. I think i might trim tonight give her a day or so and flip. Shes already filled a few rows since last post. Ill post some pictures of her babies which are topping themselves also seems like

Here is the first round of trimming under her britches. I dont know if its the all around gardner in me but when i start cutting i get way over board lol. That leafs covering that top, snip! Thats covering there snip, snip. Snipsnip....shes probably pretty sore and needs a good rest now. Turned out to be some good skeleton pics under the screen though i think. My humidity dropped from about 50% to 28% (when iwent t o cut..not after). its never done that before. If your interested Its in only FF ocean forest with about 30% perlite. Im using FF soil trio although ive only fed her once and that was last week and was 3/4tspn1/2&1/2tspn of each per gallon. Also with bonide rotstop because i usually have a calcium def with FF about this time. Budget grow style so DIY 3x2x4 box and CFLs (hince the screen ..) currently 20-23w bulbs about 15-16 2700k 1750lumens and resr 6500k 1800 lumens. So you can see my lights arnt really enough but this was more of an experiment to see if i could chop her head off at harvest and bring her back to life. Well shes living and I really dont have the space for her lol. One thing i didnt put in was a drainage for flushing so that will be a bitch if the time comes. I had to flip her early so these pics and trimming was done 1 day after flip Which ive never done. Hope shes not too mad

Nice and clean. Pic of plant top looks very nice and healthy.
