What is going on with this plant ?

This is my second grow, I am growing 5 NL auto's in coco and perlite using 5ml per gallon of remo calmag as well as 2ml flora micro and 3ml flora bloom per gallon (been working up to full strength lucas formula). 4 of them are perfect but one of them is showing signs of deficiency or something, I think it is cal but I am unsure so figured I would ask here.

Whats your ph? You wanna treat coco like hydro and NOT soil. Correct ph for hydro/coco is 5.8 ,....... While correct ph for soil is 6.5 . Buy a cheap amazon ph meter . The one i personally use and love is the blue one .. the brand is called Qimius .. id ph nute solution to 5.8 then check runoff .. keep giving water/nutes or plain water at 5.8 and keep checking runoff. For my soil grows i put in 6.5 and im happy with runoff being 6.5-6.8

I treat it like hydro and I pH to 5.5-6.0 using an Etekcity pH meter I snagged of Amazon. This is the only of the 5 plants presenting this problem (I mix up the water for all of them at the same time in the same container), could it just be more sensitive ? should I grab more calibration solutions and recalibrate my meter maybe ?

Looks like TMV

its a pathogen, you should be able to grow right though it, it will progress too slow for it to affect the plant in a meaningful way

Damn, I didn't even think about the possibility of it being a virus.

I shouldn't worry about yanking the plant to prevent the spread to the other 4 ?

You'd have to use extreme caution if it is TMV but from what I understand it isn't worth it. I'm not saying it is for sure but exercise extremely caution. Don't touch it then other plants. Keep it as far away as possible and sanitize the area. If it's something else maybe it'll pull through. Someone more experienced than me can tell you whether or not it should be culled.

If you don't need it kill i.t if you have space for her I wouldn't be too concerned , just take some reference pictures and keep an eye on her.

Thanks, I will watch and see if the next couple sets of leaves also look all messed up, if so I will likely cull just for safety's sake.
