Yellowing between veins of lower leaves – First time grower.
First off, thanks to everyone who views this thread, and thank you for all the wonderful information everyone is posting!
I am currently 3 weeks in to my first grow. I have 3 White Widows from ILGM growing in a Mars Hydro 2×4 kit setup. I am growing in Coco Coir + Perlite (Purchased as a brick, rehydrated, and buffered with Cal-Mag) and am using Nitrosol as my nutrient (Only thing easily available to me where I am located).
Today I transplanted my girls into larger containers (Adding some Mykos Mycorrhizae to the roots) and noticed that a few of the lower leaves on one of my plants is starting to develop a slight yellowing in between the veins of 2 of the lower leaves, as shown in the pictures.
If anyone could provide some information regarding what this could be, I would greatly appreciate it. If you have any additional tips for new growers using my particular setup it would be appreciated!
