I am growing lemon AK autos in Fox Farm ocean forest. Using the Fox farms trio at half strength every 2 waterings. (w/w/f)I am in week 8. Water in at 6.8 or so. Run of at 6.3-6.5. 600w mars hydro led in 3×3×6. The gro has been pretty good up until now a few very minor setbacks but today when I went to check the tent I noticed these Brown spots forming on my leaves. Any idea what they are from? I am guessing Cal mag but I do not want to give her more than she needs. First timer any help is appreciated.

Not sure where you got 3 weeks from. They are 8 week old plants.
