Does it look ok, or is there anything todo?

Plants look great............nothing to worry about. Plants with a high percentage of sativa genes will naturally be a bit lime green rather than the dark green of heavy indicas.

They are pale from the massive growth going on. I would start lowering you rh says you're at 75%. This will make the plants uptake more from the root zone to help feed the plants growth. Remember Plants still need a good amount of nitrogen for the stretch. 👍

Your Growing in soil. Try adjust your feeds to all fall in line around the same area. 6.7 is optimal. But, with 6.5,, you should be okay. LT can be a hard one to grow. I did zoom in. And can see the back of 1 node. Where it isn't been hit by light. And is purple. I can't see your leafs properly. But, it does look like you had issues with mag. Let your soil dry out, (after you have given it a water feed) 200ppm on top of your tap.. so if your tap is 200 your mag feed should be 400ppm. This should help curve your Mag issue. As you'll see those marked leafs/stem get worse. So, leave em be. Should be an easily fix. Let your focus on what she needs at least for a day or so. And these types of feeds. Are always given separate right? As I said. Your water/fert feed should be in or around a similar PH. Good Growing!

a me sembrano stare bene gli steli viola non significano nulla,se le vedi u po' pallide puoi aumentare la fertilizzazione ma a me sembrano ok!
