If its just the lower leaves it may be from getting them wet when watering.

When to start using Cal Mag?
Tomorrow my Bruce Banner plants will be 2 weeks old. One plant is showing some yellow on the left side of one leaf. No yellow on any leaf tips and no claws. I believe I may have been under watering. My question is should I/can I start using Cal Mag or should I wait longer?

Yellowing of leaves Week 9
Help! Is it normal to have such yellowing Week 9? The buds are still green, but the bigger older leaves are quite yellow. Same strain different plant still very very green. Might be the difference between topping an auto and not topping an auto?

What kind of deficiency is this?
It has been like this for 5 days or so. It looks to me like Iron deficiency but I don´t think that´s probable. I flushed her in order to get rid of salt excess but she didn´t recover any. TIA

Yellowing leaves
Hey fam, Just ended 3 weeks of flower for this Banana Purple Punch Auto. A heap of yellow leaves basically appeared over night. I fed on the 13th with flower fert (has some N in it) and again on the 18th. This is the only plant that’s going yellow. What do you think?

LIVE SOIL. too much nutes or not enough?
I think its toooo much nutrients from the live soil, and cold/dry conditions for too long. but someone else said it's lacking nutes? (I was sick, and they were a bit neglected for a bit.. ) using live soil, like I said more info in my diary thanks so much for any input 😊

Should I flush? (Overfeeding)
I think I have overfed my 2 dwarfs. Theyre showing signs like very stringy skinny new growth and yellow leaf tips. Theyre still growing and I dont want to stunt their growth, so all I want to know is if it is necessary to flush. Please tell me how to flush if so, thank you.

Could this be light burn?
Could this be light burn? Only on top new leafs. Have not fed her any nutes yet. I did lower the light after I did LST by the height difference after bending her lower. Have raised the light back up again but just wanted to check what people thought. Thanks in advance

Is this more nutrient deficiency?
I believe the yellowing and brown spots came from the roots starting to suck up more water than the previous weeks. Do you agree that the Durban Poison had some nutrient deficiencies?
