I like your grows. When i grow small, either 2 liter or 6 inch plastic pots that are 2.75 liters, i feed 2x a day and 2 ml cal mag per gal every feeding. I never see bad leaves. Maybe slight tip burn from seeing how much i can get away with. Usually i do 4 grams Megacrop and 2 ml cal mag per gal. This is Mephisto Double Grape at 6 weeks flower. Never cared to pay attention to veg times.It's amazing how quickly things can go downhill....the EM has a deficit issue but I'm not sure what's gone wrong.
Yesterday I notice the problem, which my first reaction would be Cal-Mag def but why only one plant....or maybe the others are only days behind.
My other thought is improper pH as I use colour drops which are not that accurate....or maybe being under feed as they are going bone dry inbetween daily feedings.
So I may start with two feedings a day....increase the Cal-Mag....and/or adjust the pH

I've been adding 3ml of Cal Mag for each 2.5 liter batch of nutes, as my water really needs it.I like your grows.

Yeah, i am lucky. My tap gets the Cal Mag and than Megacrop(used to be 6/9 ml GH Micro/Bloom) and is right at 6.0. Don't even PH anymore and never tested runoff. Usually just in straight coco since what i use is Royal Gold Tupar and it's clean and has nicely added perlite on its own. Hate to have to be an unlucky grower and playing those PH games XDI've been adding 3ml of Cal Mag for each 2.5 liter batch of nutes, as my water really needs it.
I don't think this issue is a cal-mag def, but I did add a touch more today
My pop bottles are going bone dry now, so I may start dual daily feedings but I don't think that's the root cause the def
I think my issue is the pH, as I'm using colour drops which are not that accurate....so I'm going to play around with the pH
In my books, a slight tip burn is not a bad thing, just means you have the pedal to the metal
Anyhow, it's only the EM that is having issues...hope the other three stay healthy
BTW: nice looking plants you have there
cheers
Man looking good.
