Potassium looks like.
I see your in rockwool. How are they being fed and how often? And what nutrients are you feeding? To me it looks like they are not being fed often enough or nutrient solution is just a little light.

I hand feed them everyday except the ones that don’t eat and still has water in them. I use flora, house and garden, silica yellow bottle and grandmas molasses ppm at 1100 ph at 6.0. It’s 2nd week of veg.

How do I fix a potassium deficiency?
How do the roots look on the bottom of the blocks?

I'm with @shottafire you need to flood your table more often or feed more also.
If they are thick and white on all of em feed them all everyday. I would also suggest reducing your ec but maybe feeding twice a day if you can. your 1100 ppm number is too much imo
1100on a .5 scale is over 2 ec on a .7 scale its 1.6 ec or so both of which are too high this depenmds on your meter that you have. i would also hold off on the potassium silicate and use light strength cal mag instead. you can add silica when the plant starts to get bigger

So... feed the ones that still have food? Wouldn’t that kill the plant? I also feed them for about 5 seconds each. Should I feed them a little longer? And what should the ppm usually be during veg?

I think it is the silica. Good point. Thank you
Your killing them right now by feeding to little.Cannabis is a heavy feeder.She also uses more calcium than most plants.
your in a hydroponic medium and they need that feed everyday to bring oxygen to the rootzone. I would bring your ec to 1.0 but feed that twice a day until runoffnot too little not too much

How do I control the ec? By lowering my plm?
your ppm is your ec. Your meter reads on a .5 or .7 scale
1.0 EC on a .5 scale is 500 ppm and on a .7 scale its 700 ppm
Hanna I know measures on a .7 scale but other meters might be different
Just cut your feed down get some cal mag and feed em twice a day
1.0 EC on a .5 scale is 500 ppm and on a .7 scale its 700 ppm
