Nutrient deficiency?

[PlastekShark]

Hey everyone!

Currently having some issues with my girl. Gorilla glue auto. Coco/soil/Perlite (60/30/10) on day 43. Using GH nutes. CalMag 3ml, GH micro 4ml, and GH Bloom 8ml. PHed to 6.1

Temp 77°F RH 55%

Only leaves at the bottom have changed. Top leaves look healthy and normal. She's kind of bushy and I have a cheap light. Could it just be lack of light hitting the lower leaves under the canopy?

You're probably on the right track. If the plants have a little age to them, because of either lack of light, or the plant using up mobile nutrients that were stored in the old fans, leave will yellow and die off. Pluck em off and just keep an eye on the rest of the plant. If things look good up top you probably don't have much to worry about.

Thanks! I'll pop them off and just monitor for now.

When they get all yellow like that, they'll probably put up little resistance and easily pull off. A decent pinch with a finger and thumb or a pair of scissors works too it the don't just fall right off.

Alright, thanks! Kind of looked like a possible Nitrogen deficiency so I wanted to make sure

You'd see more yellowing throughout the whole plant.

Lower leaves turning yellow and dying is normal. I remove these lower leaves as they start to change. From what I can tell the rest of your leaves look just fine.
