Don’t worry about those lower leaves. It’s normal for the plant to shed them as the plant matures. The plant looks fine overall.

Welcome to the forum.


Just my opinion but I’ve been using earth dust base&bloom top dressing with it I’ve had no problem at all

Agree with @MidwestGuy guy and would ask if you’re using the Grow Big with the Tiger Bloom :love_you_gesture:

I had some of the same spots. Just used cal-mag and seems to of fixed it. It takes a few days.

I’m not using Grow big, just cal mag 5ml per gal, and Tiger Bloom


Thank you

You can go on Amazon and purchase build a soil- clover cover crop and help with lots of things including nitrogen. I use it and works great.
I use lots of build a soil products. Grab a bag of there top dress soil kit. It’s awesome. Even has a few red wiggler worms inside.

Nothing seems to help maybe cannabis Sephora that is outside
