#1 Critical Kush looks very nice, I keep LST on it, and to distribute everything evenly.
I used Amanitha as fungicide to prevent possible problems. Day temperatures are still kinda high - up to 26-27 degrees, but night temperatures are 14-16, and also humidity at night is low.
I use recommended doses of nutrients, but the TDS meter shows about 400. Which seems to low for me, but all the leaves are looking good and healthy.
Yeah, that second plant looks really sick. Looks like it already had the problem starting from day one. Due to the white spots I would consider thrips, leaf miners or genetic defect. Does not look like powdery mildew to me. Not to dampen your mood, but I think she'll die in the next 2-3 week :(
Definitely keep both of the plants distant to each other. With damage like this, you can't know if its a virus, genetics, insects or just the dog hhaha.
But still, happy growing!
@Herikus, yes, she had that problem from the very beginning, and now I don't really know what to do. Maybe it's a good idea to put it somewhere far from others
