Con el amarillamiento de las inferiores, tambien podria ser falta de N. Revisa el PH que no sea que te bloquee alguno de ellos.

Can I use magnesium sulfate foliarly?
Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.

Yellowing bottom growth
Noticed some yellowing in the older bottom growth, any idea what this may be? I'm thinking my pH meter is off or deficiency, not sure though.

My two Grandaddy Purple Autos are light green/yellow in color. Is a lack of nitrogen the cause or is it something else? What do you recommend to fix the issue?

Hello, This is my first grow and now I'm confronted with the first problem. The lower leaves on my plants are turning bright and yellow. A few leaves have very small brown spots. Can someone help me and perhaps have an idea as to how I should proceed? Thanks.
