bottom leaves turning yellow

[greentoe]

so the very bottom leaves on a few of my 8 week old plants are turning yellow, but the rest of the plant looks relatively healthy.

plants have been outdoors their entire life, watered every second day (when necessary), get a weak solution of soluble all purpose plant food once a week and are still in their original pots which contain seed raising mix (about to move them into the ground though)

 

have tried searching this on the forum but there's topics on everything from potassium deficiency to heat stress.

Any thoughts experienced members?

the yellowing leaves could be your first set of leaves that have gotten old and are at the end of their life

I'm inclined to agree with Matti.

You have or have had a nitrogen deficiency. Muck around as you go and see what npk levels you plants like. Best way is experimenting.

 

Good luck

When your leaves start dying its time to start pruning cut those bad boys off but make sure to do it the right way or you'll find that the problem will proliferate as with everything there are right ways to do it and wrong ways to do everything when it comes to growing the green goddess.

I would say nitrogen lock out perhaps soil ph is out.
