Give as much info as possible. Temps, lights, nutes, water, soil or hydro, etc. One of the first things I would recommend is to take a real hard look at the underside of a few of the leaves. Look with a magnifying glass and see if you see any eggs or critters.

Are you using any Calcium supplement? My first guess was Calcium and now that you've told me you are using r/o water and orchid mix I believe that's what is going on. Also, orchid mix isn't really good for cannabis IMO. It contains a lot of bark and lacks a lot of goodies cannabis needs. You could try a special orchid food which might help. Also, I recommend a Cal-mag supplement when using r/o water.

I've gotta hustle but I can't complain. I worked in a lab at the beginning of the economic crisis and was laid off pretty quickly. Best thing that has ever happened to me. It finally got me off of my ass to do something I've always enjoyed. Now I get paid to do one of my hobbies.

What kind of lime and how are you applying it? Lime is fairly slow acting, in fact too slow for most strains of cannabis to be able to meet the high demands, especially in late veg and into flower. Also, unless you are using dolomite lime you are not getting much, if any magnesium. Your fertilizer contains zero mag if I remember correctly. Cannabis uses a lot of Mag as well.

Yeah, fast acting is in relative terms. Did you mix it into your medium before planting or how are you applying it? Too much of it will wreck your pH so be careful with it.

That could be contributing to your problem right there. The caclium your plants are able to absorb is trivial, and you are probably doing more harm than good by messing your pH up. If it were my grow, I would immediately stop adding the lime to your water. Get yourself some cal-mag and start using that. Too much Calcium in your medium will lock out other nutrients as well. You may want to consider flushing with nothing more than pH'd r/o water. I think you caught this in time but I'm concerned if you don't act quickly you will start to see these problems only get worse in the coming days. Be patient and don't try to do too much at once. Best of luck my friend and don't hesitate to hit me up if you need anymore help.
