Help! - Yellowing leaves!

Stinky, you are correct. Sodium Carbonate and Sodium Bisulfate. I flushed the plants with regular tap water last night. New growth as of this morning looks good! I will find some better ph adjusters made for plants asap.

Oh man I feel like a psychic now. That was a straight-up HUNCH based on looking at the leaf damage pattern. Plus I love salt. Hell, I'd slather BACON with salt if I had enough frosty carbonated beverages with which to wash it all down! Save the salt for the people.

I adjust the filtered water with PH-up and PH-down - made for spas/pools.

Likely not a good idea to somke anything that was grown with chemicals not intended for human consumption. Even if the plant survives, would you? Ever been in a spa with too many chems? (eyes burn, respritory distress, nasty taste...) Would hate for my buds to smell and taste the same way, right before pulmonary adema set-in.

Not to mention, the uptake of those chems are likely doing damage to your plants.

Sodium bicarb and bisulfate won't harm you. They dissociate in aqueous solution and fuck up the plants but good, but won't be uptaken in any form hazardous to humans. The skin problems from pools are most often high pH, which is VERY irritating to skin and mucous membranes, and the chloride and bromide that are used to kill bacteria.
It's moot, though- you can't grow a plant to harvest with that much sodium kicking around. lol!

Things you would want to be wary of are organic compounds- specifically, pesticides not labelled for food crops. NEVER use those ANYWHERE near your flowering plants, and be hesitant to use them in ANY life stage.

WOW, those look awful. Glad you figured it out. If you hadn't mentioned pool chemicals I wonder how long it could have taken to figure this out? I had not seen anything like those before. Congrats to Stinky.
