Do-Si-Dos auto brown spots on leaves

WOW LOOK AT DAT!! MAKE SURE DA PH OF DA MEDIUM IS PROPER TO TAKE UP CALCIUM,MAGNESIUM AND POTASSIUM DAT WOULD BE VERY VERY GOOD!! YOU COULD ALSO HAVE ENVIRONMENTAL STRESS GOING ON IN DA TENT LIKE GETTING LIGHT BURN!!!

Hi nice bush.. She could definitely do with loosing some leaves she will end up with rot in one way or another, get some air flowing through for when she's Respirating /respire loosing leaves at this point has so many positives and also in coco I try feed/water 1 day. Nothing the next, I always go for every 2 day routine like this, I know people water 50ml every 3 hours and so on but nah its crap, give more so she can last till then and get a good balance.. After that everything else should fit into place.. PH might be out slightly.. Good luck

hey 👋 A little defoliation would do it good; for watering, 1.5 or 2 liters once a day would be enough, but increase the CalMag to 2 ml/L to correct the calcium deficiency

sounds like you choose the volume of water to give rather than using what is required. At least one of your irrigtaions should be with at least 10% runoff and probably both to avoid buildup. It's also possible your formula is off, but i'd fix your irrigation habits, first. The problems may go away just from that. I usually don't suggest to remove leaves, but you may want to thin out some congestion... do not create gaps in canopy,... less is more. Overlapping leaves and leaves bunched up with no way to bend or shape them otherwise etc.. The leaves pointing down at bottom that create a semi-closed area around a damp medium inhibits airflow. MEssing with transpiration can impact leaf health on its own too. Plus, if you clear that out a bit you can more easily irrigate. as far as the light, look at recent nodes... is the spacing okay? Too tight - needs less; Too stretched - needs more. To do multuple irrigations a day, the plant has to drink fast enough to warrant it. If not drinking down at least 1/3rd of its 'full' weight, probably shouldn't be doing multiple irrigations. Again, runoff is essential to soilless growing. Get 10% runoff religiously to avoid buildup of nutrients in medium -- something that should never happen when doing things right. If you weren't getting runoff consistently, i'd run a little extra through it the next couple irrigations. ~20% or more. This will not cause a problem for a well-constituted 70/30 coco+perlite. The extra runoff will help quickly correct any buildup that may have occured.

the plant looks very wet - maybe overwatered and too much fan ?!
