Brown Spots on leaves

Hi everyone,

looking for some input on what could be causing the below issues. I have 3 plants going (Blue Dream, Purple Punch, and GG#4). They are 21 days old. RH is between 60-65%, and temp stays between 70-77 depending on lights on or off. I have not started IPM, but will use a OMRI rated foliage spray starting tomorrow.

I have been watering every 3-4 days once the 5 gallon pot is completely dry throughout. Yesterday, I noticed the brown spots starting on the Blue Dream only. I decided it was a good time to introduce some nutrients, and I top dressed and added a small amount of direct application dissolved in water. Using Term Tea Grow (7-1-1). I've also added Recharge (Compost Tea) on the last watering.

About a week ago I realized my PH was too alkaline and I was watering around 8-8.5. I have since been watering between 6.0 - 6.3 PH.

Below is pic of the Blue Dream; the other two seem to be fine.
