what is the pH of your soil? pH of the water your using to feed? is it all the leaves from bottom to top? or just the bottom? are those brown spots i see? any pest problems? how often do you clean/sterilize your grow space? how close ae your lights to the canopy of the plants?

pH varies widely and is affected by every little thing you give to your plants and is best maintained within a small, small range in soil, like 6.5-6.8 I'd recommend getting even a cheap pH tester, pH being off will affect everything you do, even if you're giving your plants the right amount of nutes - no matter where you are around the globe.

Every time you feed your plants, it'll affect the pH, but you can't stop feeding - which is why it's also quite useful to have pH up/down on hand to adjust the pH to be within the desired range, without compromising nutes that would've otherwise been overly alkaline or acidic.
