This discolored growth has managed for nearly the whole grow. The oldest leaves are not really effected, however I wouldn’t say it’s only the brand new growth.

It honestly looks just like TMV, even though I know there is no confirmed cannabis cases. It looks spot on.

Please let me know your thoughts or if you need any more info !
Thank you

I'm not sure what the thing you're refering to is. They do have an iron deficiency though which might be causing that. When the new growth is much more yellow than the rest and it gets greener and greener going out from the center, then it's an iron deficiency.

Hey I appreciate your response! what do you think is casing the lack up iron getting up taken?

I was honestly leaning more towards variegated growth, but the iron could be the cause as well.

However this odd coloration has been happening nearly all throughout veg , and never made it to the lower leaves. It normally actually ends up nice and green when grown out. Some large ones will remain slightly discolored.

I just want to be sure I am doing everything I can to keep them happy. This discoloration isn’t normal for me.

This is my first run with Aqua Flakes and SourD.

It's really mild so it's not a big deal but it's worth fixing. Like any other deficiency, it grows fine if it's mild but it's not ideal and the growth isn't maximized.

I can't offer much, but wanted to tag along in case someone definitively identifies what's happening here. The fact that it's not persistent as the leaves mature, continues throughout veg, and your plants look really healthy otherwise makes this an interesting mystery.

A little update. This sour D strain apparently is going to stretch for forever.
I’ve stopped training now for 2 weeks once canopy was full and this is how she treats me....

Bud tips are now slightly yellow, is this apart of the maturation process on some strains? I thought it was light bleaching as some of the branches are touching the light now, but it occurs even on the lower branches. And if I’m honest, the branches touching the light may look the healthiest of them all,

Feeback is welcome, hope everyone is staying safe.
