Would like to get opinions about these white & yel...

Hello there my fellow grower. Hope all is well with your girls. It's about two in morning on New Mexico. I woke and looked at Growdiaries. It becomes a obsession,growing lol.I was looking at your question and plants. Well they look nice first off. I see only OLDEST leafs doing that. If there was a time you used extremely high light or high and then low I've saw this happen to leafs they adjusting or something. The little STOMATAS. Read about them if have not ,helps. The way you explained what is happening so I got up and grabbed my book. It's called what's the matter with my Marijuana plant.(Good book) Well I was looking to see it you did not have bacterial wilt. The symptoms are small dull green angular spots. Plant soon wilts and collapses. Your girl looks healthy. Don't panic. Don't water or feed till it's ready for a feeding feel the pots weight wet and dry you will remember. I looked at your diary and you did have a light high then low go on in one of weeks. Feel free to send me a DIRECT MESSAGE anytime. I'm here to help and got a very good grow book!! I think you doing good just read and read. Best ADVICE I can give is don't ever stop even when bad happens. More good HAPPENS the bad!! I don't care about prize it's good thing but I want your medicine good. You first. I talk to some good growers too way smarter then me. Blessings on your grow. I'm new to Growdiaries but not growing. I garden alot and love every moment of it, except trim 😂. Feel free to send a DIRECT MESSAGE anytime!!

Hard to tell at this point, I do think it has some nitrogen toxicity though. Very dark glossy leaves. Look for mites on the under side of the leaves they will be super small use a magnifying glass to help see them. Then treat as needed. good thing about being in veg is that most products are available vs it in flower. Good Luck! ***disclaimer, multiple people are answering all questions as there is a contest called GOTM, when a user is selected as the answer they get a point.

High, It could be spider mites or thrips or nothing... But if you want to make sure you should use a x60 pocket microscope or a x30 juwelry loupe. These are not only handy for pest identification but you can also look at the trichomes with these microscopes to see when is the perfect time to harvest. And they are really cheap! Like 10 dollars. Happy Growing! 😋
