Your prob is your humidity. Temp and humidity is all wrong. 72% humidity is way too high, you want 65% MAX and 55%-60% ideally now at this stage. temp be better in low 80's also. Get that fixed and you will be shocked at how fast they improve. The issue is when humidity is too high, plants cant transpire (sweat) much, so they dont drink much and dont take up the nutes your feeding them. Thats why your plants look hungry now. Drop your temp a bit too as drier air AND higher temps mean plants will drink even more again so balance it out with lower temps too if possible. Make sure u have good air flow with a fan moving the air around your tent as well as good air exchange that is changing up the air in your tent/room at least a few times an hour. Fix all this before changing anything else and U will be shocked at how fast they recover. I prefer my humidity and temps lower than most pple, like my humidity in veg is around 55% and lower in flower. I also make up for this by running weaker nutes as I know my plants drink more.
