First serious grow / post multiple strains with pics is this ready?

here is some background, I'm using 2 600w hps and 2 600w MH hortilux bulbs and gold E ballasts ran 240v in my flower room. just 2 600w mh in veg room. I Started 8 seeds from nirvana, went about two months from seeds popping and then switch them all over, I'm right at 56 days of flower right now. Using FFOF with 50% perlite in 7 gallon dirt bags. I've been using the full line of Roots organic Nutrients and dry nutrients and some of the synthetics like "peak". For the most part everything seems pretty healthy. I had a moth lay a nest of eggs in the flower room 3 or 4 weeks ago and have been under serious attack by caterpillars since. that's the just of my setup I'm keeping real good temps 75 day 65 night and humidity 40% - 50%. Four of plants are looking like they are very close to harvest, any day to an additional week I'm thinking. those are 2 diff. phenos of their Master Kush one is a short doesn't seem to have much yield and one is fairly tall with medium yield. an AK48 is looking close as well as a White Rhino. I scoped out the trichs and from a couple samples I saw looks like %50 cloudy and 50% clear and maybe one or two ambers here and there, But that's to the untrained eye. There are a lot of orange pistols but on the same plant there seems to be a lot of new growth as well. here are some pics thank you for any help/opinions are appreciated.

An excess of N, resulting in relatively thin buds

thanks esdreel for responding. that's funny you say that I was thinking the same thing with the roots organic nutes they were saying to use "grow" formula all the way flower without cutting back very much. what do you think just cut out the "grow" formula and go week by week?

I order some of Master Kush seed about too start them in a week or two...how long did you veg and how tall did they get after the flip? One last question do they smell strong why I got them because I had smell problem last time... thanks....your plants look good it gives me something too look forward to when I start my master kush seeds...

I started counting from the time I put the seeds in soil after they popped open, I don't think that's when your suppose to but, right about two months, that's seedling and veg. Maybe about two feet on some and three feet on others. doesn't seem to smell too much but I also have a very nice charcoal filter that is sucking air out of the room and blowing it outside, there is constantly fresh air coming in very rapidly.

Any one out there have any experience with the full line of roots organic nutrients? I could not find much info on the interweb, but the guy at the hydro store says that's the only line he would use in a soil grow.

I am pretty sure they will say that to a lot of product if they receive a little incentive,
Dyna-gro works great

I ran a Roots kit with one grow, I wasn't too impressed but it gets the job done. I would begin flushing at this point if you haven't already. I will tell you that the longer you wait the better.....your master Kush and Ak48 plants are not ready IMO. Probably another feeding or 2 on them and then 2 or 3 flushings.......I have found about 3 days in the dark before you chop them will help you too and be sure that your soil is very dry before those 3 days.........works great 4 me.
