Fml what’s wrong

Y'all this is my first photo bc I got sent the wrong seeds. I’m into week 4 of flower and getting these spots. Send help pls! White Widow DWC grow. Mars hydro Ts1000, general hydro FloraTrio, calmag, and hydroguard. Temps flux during day between 70-82 and night between 66-70. Rh% was at 38 bc my damn monitor broke so trying to get that up. Water temp 60-75. Ph 5.8-6.2.

Have you checked for bugs?

Too much calcium maybe.

What is your EC?

Cal mag craze strikes again
