Bring it up to 1100PPM with micro, carefully.
Use koolbloom powder to get to 1100PPM for the last week before flush.
Don't sweat the N,it comes out in the flush unless you WAY over-do it.
Great looking plants! Useful for me to see this as I am also flowering chem D aswell from clone.
Mine are about 3 weeks and are starting to smell a bit like shit/garlic/meat...very pungent!
Thanks

I use a constant-read digital PPM/pH meter
