It could be from the nutes I used the other day.Gibs-- we need some info: soil brand, if you've fertilized, type of lighting, and the T and RH for starters,... I see possible heat stress, in the slightly rolled edges, which could also be causing the leaf distortion, though Arty is right, many things can cause that (forget viral here),... the tip yelllowing hints at something being a bit too rich, or off pH,...
My soil mix is about 1/3 perlite and 2/3 fox farms ocean forest. I have given the plant half a tsp of nutes 2 days ago and I think that may have contributed to the yellow tips. I'm using hid lighting which I know was way too close to my plant previously. I calibrated my ph meter before feeding so idk if that is it but it may have been too early to feed and the nutes in my soil may have overloaded. Also my temps are about 73-78 and my rh is around 50 now(I've been running a cool must humidifier to combat low rh).
