Weird coloured leaves
The leaves are yellow a bit on the outside and just today noticed that it looks kind of black too. Anyone know if this is because of a certain deficiency?

Black marks on leaves of a slow grower.
Noticed there's black markings on the edges of the leaves on our slowest growing plant. My initial thought was water droplets sitting on it before it had fully broken out or could it be something else?

RunWithIt
Popped up around last week (week 4, monday). Prior to week 4, i had been watering with tap water, which in my area is pretty hard.(7.8+ pH) Been correcting pH to 6.8 with each watering since. (2 waterings since then.) Should i just continue feeding 6.8 pH water or add cal-mag?

Problem with plants in the 3rd week of vegetation.
I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.
