So, I have this issue here, and this is the only one this bad, but I do see this on leaves throughout my entire grow. I’ve never seen this before. Hoping someone can shed some light on what may be happening here.
I’m using Athena pro line right now. Running at 3ec. How much run off are are you getting after watering? what size pots? If you’re in flower once a day watering is going to dry out the coco too much especially if youre in a smaller pot. Dry backs are absolutely fine as long as it’s not bone dry otherwise youll burn the plants. Perlite is also going to aide in drying so if you plan to do less frequent watering ditch the perlite next run. hope you get it sorted!
ya some kind of weird salt buildup or something is likely. if possible feed with your regular solution next time (or a bit weaker) and a ton runoff. like if it takes 4L for them to start dripping out the bottom then run 8L through them to clear the old shit out
I would flush it with something like Bushdoctor Sledgehammer. It works wonders for me I do it every 3 or 4 weeks I just add it right into my micro nutes after a good watering of plain water. I also add 1/2 TBS of molasses per gallon of my nute feed once a week in coco
I think people worry about PH to much. I add pure dolomite lime powder to my coco/peat/perlite 1TBS per gallon and I don’t PH anything. My tap comes out 7.0 tho. Foxfarm is PH’d at 6.5. Try uping your PH to 6.5 I feed sometimes twice a day Peace
