Budget LED+CFL Grow from Chile w/love

A catastrophe happened, The 4 Eleven Roses died from what i expect, veing shadowed by the other bigger plants as i found the corpse of the plants very stretched, like they were searching light (i don't know how to mark this on this platform) . On the bright side there are 8 female examples, 4 g13 and 4 santa bilbo full of hell flowering. There is a bit of plague, but thats also a negligence i caused by reusing soil from the outdoors. Why i highlight this? because, as the plant are near mid flowering, the use of foliar sprays will not longer be a viable option and i must stick with the basics. Kind regards homies.!
