First grow. Plants are looking sick.

[Bubba420]

Hello!, this is my first grow and my new growth is yellow. I have no idea what’s going on. They are in an organic soil I buy from the local grow shop. I believe it’s just Promix HP that he amends. 3 gallon fabric pots. The plants are Rambo clones that got cut about 5 weeks ago. VIVOSUN aerolight 100 set on 65% 18” above plants. Temp runs about 68-75 50% humidity. I brewed Roots organic terp tea grow last week and fed them last week. Other than that they have just had water. Any help would be greatly appreciated.

How much water have they been given and how often?

I’m watering every 3-4 days. About half a gallon between the 2 plants.

To me it looks like a magnesium deficiency.

I'm going to agree with TheGoldenRoad on this one
