This just started happening a few days ago and getting worse. Affecting lower leaves. I have 2 plants (Napali Pink) and this is only happening to one (right now). I’ve looked under a loupe and don’t see any pests. Can anyone help? I’m one week into flowering. Both plants have the stems turning purple but that started over a month ago.
Growing indoors
Using FF trio every other feeding + Cal/Mag, using distilled water.
Temp and humidity controlled
Lights: Mars Hydro TSW2000 keeping at 75% and 23 inches above canopy
Water in @ 6.0 - 6.5 ph, water out at 5.8 - 6.0
TDS in @ 2100 and TDS out between 1200 - 1600
Growing in fabric pots with Recipe 420 soil
Good drainage and I vacuum out any runoff.

Not sure if I can help. I’ve not seen the type of leaf issues you’re having. If possible take pictures of whole plant in natural light. I’ll probably have to tag more experienced growers to help.
Thank you! Maybe @Myfriendis410 can help??
Good one to ask for help from @Myfriendis410 has helped me more than once.

Looks like nute burn. Your input TDS is 3 times too high IMO.

Besides the high PPM your PH is low. 6.5 is sweet spot for soil. I suggest adjusting PH input to around 7.0 the next water and check run off. Hopefully that will get your run off higher than the 5.8-6.0 you had last time. Adjust future waterings/feeds accordingly to get run of around 6.5
