This is a photo blueberry cheesecake from barneys farm. Left for a few days and let the girl water her with pre-made nutes. Only thing I can think is she gave her plane water lol. Just odd as I've never saw this in veg.

Coco charged with calmag at 150 ppm.
Using megacrop 2 part at around 500 ppm and 200 ppm capmag. Water is PH'd to 5.8-6 She was started indoor but has been outside for about 2 weeks now getting 8 or more hours of direct light. Before that LED lights at 20 hours.

If your megacrop contains micronutes and your feeding acording there instructions there shouldnt be any nute defiecence and your also feeding calmag this shouldnt be happening.Somtimes you can use to much calcium but i dont no about ppm tat much to tell if your over or under feeding.

Well I've been adding an additional 200 ppm of calmag on top of the megacrop. Perhaps that's too much.

My understanding is that 2-part MegaCrop contains a good amount of calcium such that it typically doesn't need supplementation for autos. [Get further confirmation].
