Ms. Hindu - First Balcony Grow ever

I guess pre-flowering has started? If so yeay. We have a heat wave starting with almost 40 degree C. So lots of sunlight. They both grew nice and bushy. I found some light spots on their leaves, dont know what those are? Also I saw a little tiny black bug walking on the stalk... Wondering if LST is still good in pre-flower. Update: After some research found out that the white spots are spider mites 😱 I removed some of the leaves, where I saw the bugs actually walking on it. Ordered some neem oil and some Aptus Dislike. I hope I caught it early enough and we can safe the babies. Update Day 42: Hallelujah, what a week. First the bugs and neem oil huzzle, now Ms. Hindus sister Northi had a sunburn. So much sun and not enough water. Need to adjust the watering schedule. Also we cut off some of the dried leaves which we now got told not to do. You live and you learn I guess.
