Wilting leaves and copper spots? Save Me!

I'm just a newbie here too on my first grow (starting around the same time as you). Got very similar problem with my Pineapple Express Auto grow - the pictures look very familiar. Mine's almost certainly happened because of self-inflicted overwatering issues. I'm just going to let my soil dry out thoroughly before watering again. It's not a quick fix but hoping it will do the trick.

The overwatering will give you a crappy root zone, leaves won't have to be wet or soft for it to be overwatered. I still think bad watering practice. Let it go dry, feel the pot, lift it and you'll know if it's dry all through or not. Look at the holes in the bottom if you have to to see if the soil is wet. When it's dried out give it a light feed (because of the yellow leaves) , and do it so you get a small trickle come out the bottom, not a gushin, a trickle, then it's watered through. Then give it a few days and lift the pot again and you'll get used to knowing when it needs water/feed. Atb

Unfortunately, I don't have the resources for RO water. I just started using bottled distilled after using bottled purified water. The leaves feel dry so I don't think it's overwatering.

Looks overwatered. Maybe a slight N deficiency. If you're using RO water, you might need calmag too.

I just did a quick slurry test and the pH is 5.05. I do have pH up/down on its way but not fast enough. The canopy is 19" from the light at ~95%. In a prior question I posted, I was told to keep that baby cranked to +90%. Now I should turn it down to 70%? To test is she needs watering, I usually feel the soil knuckle deep, pick up the pot to see how light she is, and check the deeper soil with a moisture meter.

Hey Mate, Are you running your light @ 100%? And your pH is a bit low for soil imho. Seem to me it's wether light stress or she don't like the to acidic soil... First of all I would dimm the light down to 70% and look how she's developing further. Good luck and happy trails for the rest of the way 🤞! Servus Oim.

Have you been letting it dry out fully, through the pot, before watering again? Or do you just wait for the top to go dry?
