Might need to lower your lighy, it seems a bit stretched already. And please, please go to 18/6, cannabis NEEDS sleep to finish its photosynthesis cycle and have a correctly functioning metabolism. You will not lose yield, size...... anything by going to 18/6, in fact you will actually gain much due to the plant having a correctly fuctioning metabolism. The myth that it is ok to grow cannabis (or any plant) for weeks/months without sleep needs to be removed from the internet forever and asap! Only someone who does not understand photosynthesis or how plants function could ever recommend for people to grow with 24/0! Your plants leaves are already showing signs of issues, perhaps hunger, perhaps stress from the lack of a dark period. 18/6 is scientifically proven through 90+ years of research into cannabis as the most effective and healthiest light/dark schedule for autos and photoperiod plants in vegetive growth. Personally I would trust 90+ years of scientific research over any sort of bro science/corn flake packet science. Besides, cannabis can only grow so much during any one 24 hour period and this growth "tops out" at around the 18 hour mark, meaning running your lights longer than 18 hours is basically a waste of electricity. Anywy, it is never too late to go to 18/6 and rescue your plants from their "torture regime" of sleep deprivation. Hope this helps, Organoman.

U went from a seedling light to a real grow light and now the plants have responded by exploding with new growth and they are a little bit hungry, thats all. The older leaves look fine so its likely just very fast new growth and the color will come in over the next few days, if not then try making your next lot of nute mix a TINY bit (like 10%) stronger and start changing the res a lil more often too if your going longer periods between changes. But honestly its not really a problem at the moment, more a watch and see and maybe tweak things a touch type deal here ok. Not a problem. Plant looks REALLY nice other than that so it may need slight tweaking to dial in, but its NOT a problem. Dont go changing things alot as that will make it into a problem. Small changes IF, and only IF it doesnt improve on its own in a few days ok.
