Looks great man, big plants, very nice!!! Since you are doing very well, cut back on the nutes, they don't need quite so much when they are so dark green, allow them to use what they have in the leaves a bit.
One thing I learned about nutes a while ago is when they are dark green, cut back on the nutes, just give them water for a lil while, then add nutes slowly to prevent them from burning. I've burned my plants myself with both chem and organic nutes by going too strong, so I don't nute them anymore when they are really green.
A buddy of mine doing 1st hydro in rockwool burned his plants many times, until I finally convinced him to dilute the nutes, then they were fine, but in budding he still was too heavy on the nutes, and I KID YOU NOT, this bud looked good like hydro, full of crystals, but did NOT get you high, and when you would light the bowl it would spark and crackle and ignite itself and burn away.
Especially in late budding you want to flush or keep the nutes down. I always find the flavor to be 100% better when it doesn't have much nutes at harvest. I can't stand that fertilizer taste some bud gets, and I don't use miracle grow soil anymore for the same reason, the taste is bitter and harsh compared to properly flushed bud grown in better nutes. Since you are using hydro nutes, you can get it to taste very good when you flush.
