New Grower lower leafs yellowing on plants , advise needed

[bigdee]

hi I have a couple of auto rocking away there on week 5 and I've noticed on 4 or 5 of the plants a number of the lower leafs are starting to yellow, I've read it could be a number of things !! I reckon its under fed , anyone else think different? and if it is under fed how to correct it??

Come on dude.. give us a bit more information than that.

How is anyone supposed to give you an accurate diagnosis with the following information "week 5, lower leaves yellowing"

What kind of medium are you growing them in?
What kind of lights are you using?
What kind of nutrients are you using?
What strength have you been feeding?
What pH have you been feeding?
Have you checked the pH of your medium?
Do you have any pictures? (close ups and full length photos)

I like to help people bro but you're not making it easy for me.

1 of 2 things. Either your plants have nice canopy and the lower leaves are not getting enough light, or your plants are going into flower which is normal to see lower branches yellow. A pic or more info would be nice but if she looks healthy other than the bottom brances,I can bet its one of those two things :Sharing One: give us more info or a pic and we can go from there.

Also, if you've got pH readings on your feeds and your run off they would be helpful as well.

Yep, capture and test the water that runs out the bottom of the pots. That will give you a fairly accurate reading of your soil pH.
