HELP! Identify Leaf Spots

[Foxtrot7]

Can someone please me identify the problem with this plant. They are in week 6; about two weeks into flower. They have been growing in super soil without additional nutrients. These spots just began to appear within the last week. Thanks for any and all help.

Potassium Deficiency What is the feed life of your super soil ? If it's at the end stage you may have to give some organic nutes during flower as a boost. Are you foiler spraying the plants or misting, the leaves indicate it. How far are the lights to canopy? How often do you water? How old is the soil? If your soil is not adjusting itself (PH) it may be causing your problem. Good Growing !!

Look to treat the single element based on super-soil feeding or boosting super-soil. This may help. https://www.smilinggardener.com/collection/all-about-soil/
