Spots thoughts?

Any ideas guys

With a issues like that it would be very helpful to list soil and nutrients you're using and if you're using a ph and ppm meter to measure and adjust the nutrients so they will work precisely like we like and enjoy

Water? RO?

Sorry guys.
Soil is a mix of premium organic soil with perlite, coir and peat moss.

Ph is at 6.7 and ppm is at 300-350 between plants on last watering.

I do use only powerfeed plant food with fish and liquid compost only.

I do mist occasionally of just tap water to help keep humidity up but mainly consist of around 30-35%RH

Some leaves are getting worse i did end up buying some trace elements which i will add in next watering this weekend.
