weird speckles and brown-ish spots

It's hard to say for sure without a detailed diary! You need to track the changes in the plant's condition! Every week, you should note the information about the acidity and ppm of the watering. Keep track of the nutrients and dosages. Right now, it looks like a deficiency! But the question is: "What triggered it???" There's a deficiency of phosphorus, potassium, and magnesium here... You need to keep a diary, bro! Any advice right now could be useless. In the soil, such hell is caused by an overly acidic environment! Check it out, bro! Good luck!

thanks for the help man, yeah i checked the ph of the runoff with some of the liquid drops, and it was well under the lowest number on the guage. it was bright yellow, super low pH.! ordered some pH up and down, hoping that helps! also ordered some calcium, hoping i'll be able to return one. i really don't wanna get into adding extra stuff to the soil and having to worry about pH a bunch.

Calcium deficiency would be my first guess. Other than that, bad pH comes to mind.
