fox farms ocean forest now vs. last year!

so, i started growing in FFOF, and still do now, i think within the last year things have changed?! i used to start feeding after 3 weeks of being in their 3 gal. pots, and all was good. i am doing a miltiple SCROG grow this time around, and i started feeding 1 at 3 weeks in ( hard to explain, but i start feeding when my girls tell me to) and the other 3 are loving life with nothing at 5 weeks in, the first one i started feeding at 3 weeks ended up with a MG def. and P def...in veg yes, but its fixed, and havent fed since...all of them are nice gorgeous, and i want to say i have exceeded my own expectations. My question is has anyone else noticed a change in FFOF? like almost a fluctuating soil mix? within the last year?

I switched to happy frog, my buddy at hydro said that FFOF is rich in nutes and if going to be supplementing nutes to soil anyway wouldnt make any sense to pay more for the FFOF, I always had a slight nute burn nothing major.
