Brown issues on leaves

Hi. I am feeding with advanced a+b. Soil has organic nutrients like guano and bones. Outdoors with lots of heat and humidity. Any ideas? Thank you a lot!

Those spots are likely from pH. I'd cut out the a+b, run plain water. Check your ingoing pH, target 6.5
If the plant looks hungry or could be pushed a little more, then hit it with a light dose of AB. Not sure which formula your using sensi or conni, but your liquid nute should be a bloom formula.

Also this is a big one, if your going to feed any liquid nutrient, alternate with feed, water, water, feed. This will help to use up/ rid accumulated sodium and assist in pH control. It's way easier to hit them with something than it is getting it out.

Thank you. But wasnt advanced supposed to fix ph?

looks like burn marks from the sunlight magnified by water droplets to me.

I've never had luck with their "pH perfect" in soil. Perlite and vermiculite @50/50 dtw, oh yeah it's good. Just over priced and over hyped. Fulvic acid isn't a secret, but advanced nutrients sure thinks it is

I decided to check the roots. And they dont smell good. Little mud too. Must be that. Changed the soil partially because it is blooming. Flushed and then put some water with peroxide. Lets see. Thank you.

This is how the roots looked like
