Nutrient deficiency?

Hi. Initially thought this was a nitrogen or magnesium deficientcy due to yellowing of lower leaves but there are also tiny yellow spots. Any help greatly appreciated.

Its a dwarf sativa/indica hybrid, grown in soil, about 2 weeks into flowering.

Thanks.

Are you using R/O water or distilled? What kind of nutrients are you useing and how much? What PH are you feeding them?

Just from the photo's, I would say they are turning Yellow from Lack of Nitrogen. Kind of soon in the flowering stage to already having this happen. How long have you been feeding them flowering nutrients?

I agree lack of nitrogen

What type of dirt/nutes?
How much and how often?
Possible under feeding?

I'm just using tap water and standard tomato feed (half the suggested dosage). I'm waiting on some kit to be delivered so that I can test the water quality.

looks like magnesium def. green veins, surounded by yellow leaf. could be hard water. too much calcium locks out magnesium.

try flushing with spring water. then water/ feed with spring water.
