Tried searching. No luck finding the exact same problem as mine.
I have 4 plants, 2 showing a few white patches, otherwise extremely healthy.
Using Fox Farn Ocean Forest soil. Grow Big, and Big Bloom fertilizers after 2 weeks.
Was nuting every watering. Found out it should be every other watering. Just started watering without nutes, so I can now do the every other watering suggested by Fox Farm.
The two plants effected are 4 and 6 weeks old. Using 400W MH and a 150W HPS.
My PH was a tad acid at 6.0 or so. Increasing to 6.5-7.0 with PH up. I haven't started that yet.
I was using tap water from a spicket that did not contain the water softener salt pellets that the rest of the home has.
I think I have narrowed down to:
Magnesium deficiency, or nute burn.
Reason for mag deficiency is perhaps PH too low, nute lockout of magnesium. Or, maybe the water is too hard.
I also have a cool air humidifier that was blowing a couple of feet away. Not sure if the mist could have something to do with it.
So, I'm going to use the water softener water, make sure the PH is 6.5-7.0, and use nutes every other watering now.
I have ruled out any kind of overwatering, as I only water every 3-4 days. Also, ruling out heat stress, because then temps are 68-76 degrees at all times. Ruled out any kind of bug, because I looked everywhere for them, under leaves and in soil.
Please help.
