Hey there, i'm no expert, still spending most of my time reading and getting into knowing as more details as possible but i'm pretty sure experience is the best teacher. Anyway in my humble and maybe ignorant opinion i think what you are dealing with is Nitrogen Deficiency because the yellowing is starting from the older leaves meaning that the plant is draining them to continue growing, fact is every little problem with these ladies is interconnected. Try raising your RH a little bit, might also be a factor, try at least keeping it over the 30%! i also see the leaves are drooping and a lot of runoff water still under the pots so you might even be overwatering them maybe ? (although with a RH as low as yours i can see why that might be a must in your case).Check this chart out and check your plants, then re-check the chart and re-check the plants again, you will eventually find the one that suits your issue most ->

. Also check out this useful thread on possible problems - > Cannabis Plant and Pest Problem Solver - Pictorial
And try and keep the environment clean of all the other dead leaves that i see on the bottom in the draining area as it might result in pests and other unwanted problems.

okay igrow I will definitely try to solve all those problems and hopefully they start to come back to life. I just threw some Botanicare grow on the last water so we will see if that helps with the nitro problem. If you have any other advice for getting that nitrogen back up shoot it my way. Thanks for all the help !!
