Random brown spots

[Oldenred1]

Getting some random brown spots on my leaves. Using Advanced Nutrients. Currently around 600ppm and on week three of grow. Any ideas of what might be wrong? Thanks

How is your temps and humidity? Could be the beginning of a problem. Are you using a calcium and magnesium nutrient?

Maybe try an epsom salt foliar spray at 1 teaspoon per gallon.

Temps are 75-80 humidity is 50-60. I have been dosing cal mag but like the base nutrients I have been half dosing. I’ll try stepping it up to see if it helps.
