ok. your feeding was from week 4 on on the low side,,, so it is like i said, she canniblised herself
and i found the brand of your light the P-2000 of viparspectra
so your light distance is quite close ( or did you dimm them down =? )
iam wondering why they still grow so open , with that strong light.
but it would be apart of the issue too, because to me the look burned from above and underfed
so find the balance in your grow , and plants will drive
