Increase Nutes?

Looking ok, but over fed and VERY dark green. I too would suggest dropping your ppm even further. Remember too, it is very easy to fix a slight under feeding, but very hard to rescue a burned, over fed plant. Acapulco Gold being a Sativa, needs much less nutrition than your average hybrid or indica. Run your lights at 100%, sativas love light and your plants will need maximum energy for growing maximum flowers, just play around with the height of the lights to keep your plants happy.

They look fine to me. I can't see any burnt marks from light or nutrients. Your ppm seem low for this stage on photoperiod. If I was you.i would either -Stay like this because there is no issues. Or - increase nutrients gradually until I reach at least 3/4 of full dose or until signs of too much. Or/ and -Bringing the light down couple inch every 4/5 days and see if it looks like they Ike it or not. You need to play with your light and nutrients a bit. You could hurt them if you do things to fast so be patient and observant while trying things. Also I would do the nutrients and light changes, not at the same time,so you know what is impacting the plant.

800ppm is way to high. Your good see toxs as that's when they show up more often than it would in veg. You have to be very careful with Synthetic nutrients. They are full of salts..

NOO. I can see on your tips. Very very light nutrient tip burn. If anything leave it for now. As she comes out of PF then raise her up lightly.. its better to have a light def then a full blown tox. Your growth is very very green. And you are doing hydro. So, if anything, I'd think about pulling bk maybe. 3-450ppm max + ambient tap ppm. So, if your tap is 100 ppm aim for 550-650ppm total. Good luck.
