<span class="link_user">@lotuslord</span>, nothing ever recovers, but main thing for it not to spread, they will grew new leaves, don't worry ;)
even with ridiculous picky plants, were i had it too, i sorted out it at the end, here you have good cheat in transplanting and kind off resetting all to factory mode ;)
just maintain it after, i gave you all options witch could lead it too, you have to find answer yourself, only you know everything what you have done.
like 8 and 10 photo of week 3 and 3rd of week 4 , transplanting will recover and boost them a lot tho. Nothing to worry like.

<span class="link_user">@AsNoriu</span>,Thank you very much for your help mate. I've always been monitoring water p.H. and my tap water has an E.C of a bit over 500, so there seem to be lots of minerals in there.. Anyways, I just ordered some calmag supplement and will transplant my girls in a few days.
Will the bottom leaves recover from mag deficiency?
