Difformed and amputed leaves

Hi there,
My friend have gave me 6 mama's about 2 month's old so i could start a new cloning business.

But they were on 12/12 mood at the time(for 3/5days) and had started having white filament on the top.

I put them back on a 18/6 round lighted with a 1000 mh.Since that i had major problem's with them.

-At first, all the leaves had start to burn from side to center after i had uses 20/20/20 600ppm.That problem has almost resolve now after a few(3/4) watering with plain water(6.5 ph.)

-I changed them to new pots since they where a little bit tight in their 8 inch pots to 11" diameter.(the're about 35"high).

Yesterday I used B1 at a 1000 ppm for the first time in two weeks.

They started to grow again but the new leaves getting out of /or between the white filament are amputed nor difformed(1 or 2 or 3 leaves per stem).

Can it be caused by the fact elaborate here?
Will they replace themself?
Will the next leaves will be 5 branches?
Can i believe that i will be able to use their clones?
Should i cut their head off removing all the white filament?
Is there anithyng else to do except to wait and see they are on a good track?

P.S. If my english is not to good please, be nice and understand that french is my native language

when a plant is regenerated that's what happens...single and 3-leaf sections instead of 5-7-9 or whatever grow for a short time...it's normal and will go back to it's regular veg growth in 3-4 weeks. do nothing different from your normal veg routine...

Thanks Del for your fast reply. You reassure me
