Round Leaves???? Help!

OK Peeps. So I opened my mini-grow cupboard today to find the new growth on my 2 big-bang plants has gone weird. The leaves are coming through single (not in 'fingers') and have little to no serrated edges. Both plants are showing this. They are clones from a plant that I grew out fine. All the other plants in there are o.k. (basil, sweet peppers and chili peppers).
I'm in hydro, flood/drain, p.h. 5.6, e.c. 1.3.
Apologies for the photos but my camera is crap at taking pics with flash.

idk man... you got any light leaks ?

It's kinda hard to see, but it does kinda look like they are trying to re veg!! Check for light leaks and make sure your timer is set right and working!!!

They are re-vegging. For reasons too complicated to go into, they had to go into a flower cupboard (12/12) for a week early on in life, soon after rooting. There are no light leaks and timer is set to 16/8 now (is in my bedroom and fan keeps me awake). I've never re-vegged before. Is this behaviour normal?

Very normal if you intentionally re-vegging!!

Cheers dude. Any idea how long until things return to normal?

Its revegging and so it should it was tiny ,why is it growing with that other plant that is dominating the pot?

about 2~3 weeks give or take

^^^^^^yeah what he said! Sometimes you can get some crazy ass growth during re-vegging. Let it grow as it wants, sometimes the crazy ass growth can give added branches and can increase your yield! Remember I said sometimes!!

Thanks guys.

BUDS, I only need so much weed. I also need Chilis and sweet peppers all year and in spring, seedlings of tomatoes, cucumbers, aubergines, coriander, broccoli etc.

Skefaman, Thank you for a time estimate.

Old dude, I will take that into account. When I grew this plant from seed, I made the mistake of fimming at the 4th node then topping at the second node after that. Big mistake. Had more tops than I had space for but still managed to pull 6oz without mould(rH shot up to 65% at end of flower) I consider myself lucky.

lol all you can really see is that huge ass plant taking up all the space... why dont you just get a seperate spot for your mj plant and solve all your problems

I think I have 9 peppers and 3 basils in there now. They are as much of a priority for me. I may cut them back as the vegging moves on but why not use up the empty canopy space atm? It' a U-scrog so I can easily move things around as needed.
