So I have 6 plants that are having this issue with brown spots on the leaves and some are curled up and getting yellow. I water with tap water that is Ph adjusted to 6.5ph. I keep trimming off the bad ones but the problem is not going away, thought it was nuts burn but I only gave a little to them weeks ago. Is this calcium deficiency?

10 weeks in same pot of soil with I’m guessing very little nutrients given so far if i understand correctly?
They look very hungry. I would give them a really good feeding with plenty of runoff.
Having a good understanding of ppm/tds would help. But typically after a 4-6 weeks, most start supplemental nutrients with regularity depending on the nutrient line used…
Thank, yeah, I’m now thinking lack of nutes.
Welcome 
we look forward to seeing your plants makin big buds. Good luck!
Welcome aboard! That lady looks hungry.
Yes, looks hungry. Also looks like there might be a micronutrient deficiency… I use Peruvian Gold Micro-Builder.
Welcome aboard we’re glad to have you.
What nutrient line are you using? You really need to know the TDS going in.
This implies you are using drops or strips instead of a digital meter. You need more precise measurements of PH.
Is this total amount of light over six plants? If so you are way under lit. You need more like 150 watts per plant.
Hi there
Pots too small.
Try to get 5 gal fabric pots.
What kind of soil?
6 plants gonna be crowded.
Please check your ph and tds of runoff
Get good pens by apera or bluelab.
You can fix this. These are only suggestions anf MHO.
