The leave taco shape implies heat stress, but the tips show light burn so try to put your lights much further from the plants

So... the brown spots in the last 2 photos. Are they Ca deficiency? Will I do extra damage if I add Ca/mG supplement? What is the upper concentration of Ca/Mg concentration for cannabis in DWC grow? How can I tell if I add too much Ca/Mg? Help please!

whats wrong with the leaves?
Im sure this is nothing to worry about but i just want to know what it is. Is it genetics or is it a deficiency that i can sort out. Im only feeding water at the moment. Also is there a name to refer to this condition? Because its not twisted or wilting?

Tobacco mosaic virus
My strains do have the tobacco mosaic virus. What does this mean? Should I kill the ladies 5 weeks before harvest? Has anybody experience on yield loss with this virus?

Nutrient lock out hot soil question - stunting starts on 3rd set of leaves always?
I noticed that they always deteriorate when the third set of leaves are forming. If these are in fact stunted from the nutrient lock out due to hot soil, does it make sense that growth is vigorous until the 3rd set of leaves form?

Calcium deficiency?
Hello everyone, I need your help once again. I have just spotted some brown/yellow dots on 2 leaves of my plant. Did some research and looks like Calcium deficiency, but still wanted to ask you. If that's a Ca deficiency, should I add CalMag next time I feed her? Thank you ✊

Hi all, my plant pictured here just went through its first root explosion and is now dipping into the water at multiple points. EC = 1.0 and ppm (0.5) = 490. Does this look like nutrient burn? Using Flora series with CaliMagic.
