These are some of the bottom leaves of some of my plants...checked ph and its 7.0... I water/feed/water/feed every 3-4 days.

Some are much worse than these with similar patterns, yellow around the tips with with small brown/yellow spots sporadically.


If it is a phos/nitrogen problem should I flush them? Also If should I wait till scheduled watering or do it immediately. Grow is 3rd week into flowering.

Thanks for all your responses and +rep for anyone who can give me correct advice.

If those were my plants, I'd just water til I could get the yellowing to stop. Might consider epsom salt (magnesium) as that's what I did when my plant leaves started yellowing and I wasn't sure whether it was nute burn or mineral deficiency. Good luck!

You are awesome. I know what epsom salt is. Do I mix it in the soil? Dissolve in water? How can I apply it?

Thanks in advance

heat it up so it dissolves then you can put it in the soil (after it cools) or foliar feed for a faster result

Heat it up and then just pour it straight into soil after cools or dilute?

Any recommended dosage?

I would dilute it with water and then feed through soil as well as foliar feeding with a spray bottle. I had similar issues and I just flush the soil to eliminate the possibility of overfeeding.

If yellowing continues after a good flush, then I consider a nutrient deficiency and start giving nutrients that it might be lacking.

A good way to avoid these issues is to simply feed with organic nutrient. I use Fox Farm nutrients - Grow Big (which isn't 100% organic) and Big Bloom (which is). After I switched, I've never had issues with over-ferting. Hope that helps...
