Grow Mediums New Growth Lime Green. Iron def?

[Muddy]

16inch and no closer.

I could only view the thumbnail yesterday, today I can see the enlarged picture. It's not bleaching, which I wouldn't expect from that light at that distance. The yellowing with the veins still green suggests magnesium but I would expect to see that on the lower, rather than the upper leaves. Same with iron. I agree, up the strength of your nutes a little. If it's too low it would likely show on the new growth first.

Did we try and up the EC? Might just solve the problem

Its next on my list , around 8 hours ago i supplemented with 8ml of iron and i think its looking a little better?

Yo peeps! Just found the problem and wanted to share! My ph pen needed recalibrating, was out by 1.0. Should have checked this 1st! How embarrassing!

Haha its always ph in some way, good job on figuring out ur problem so quick.

Early ph issues effected growth so she's a little small which is a shame. 2nd pic still looks like i've got a deficiency. She's probably around 2ft tall and very compact. 6 Weeks in and just starting to stretch. She's not drinking very much - currently on an ec of 0.5/0.6 , i measure every day but the ec doesn't seem to drop through out the week so i'm tentative to increase, is this wise?

Smells amazing! Ive never had a plant smell as much in veg as this. She's stinking out my space.

Thoughts/criticism welcome!

She's not looking too bad at all mate, I would say you can up your ec some more at this stage. As long as you continue to monitor your levels you will know if she is happy or not with the change. 2nd pic is kinda hard to tell what'g going on but looks like yellowing between veins so yeah just up the EC slightly and you should see an improvement. Don't worry, when they start to stretch in hydro they go for it, she'll get bigger yet
