    Do you feed Cal mag? LEDs require more Cal mag than other lights

    No I do not, the leafs that are effected are ones closest to the light, only 3-5 leafs on 2 plants are like this. Cal Mag deficiency? or light burn

    calcium deficiency check runoff ph (probably low)

    flush them with 1/4 strength nutes until you see it stop that and new growth returns to normal. You probably overfed, which built up and blocked out the calcium OR your ph drifted off and caused the lockout either way the fix is the same. Good luck keep us posted.

    I use led lights as well on some grows and I can tell you that 12 inches is to close and you most definitely need cal mag .

    Today I fed with 1tsp/gallon of Cal-Mag plain ph water at 6.4. No other nutes. The runoff was 6.2. Hopefully this helps her out, Il keep posted.

    Up the ph to 6.8 for how long? Im going to have to wait until next water which will be Thursday since I just watered today.

    I would do it for two waterings at least to make sure you don't get a lockout at all
