Brown and yellow spotting

[Hdlato]

I have a few plants that are having this problem with the leaves having brown and yellow spots on them. Any idea what this could be?

Assuming your using quality nutrients & mixing them the way the label on the bottle tells you to, I would say you have ph problems

I was thinking the same thing. Ive been feeding from 6.1 to 6.4 ph using athena pro line

Ideally you want to use the whole ph range from 5.5 to 6.5. This chart taught me a lot about which nutrients come available to plants at which ph levels

See how boron phosphorus & manganese are better available at the lower ph range, then if you look up how a plant is affected by boron, phosphorus & manganese deficiencies you see how important it is to use the whole ph range

Are you letting that soil properly dry out? Looks very wet to me

I am growing in a soil medium not hydro at the moment

Yea only water when its dry about a inch or so below the top of soil

Still applies though not as dramatic but this is the chart for you

Also in soil pay to check the ph your runoff water comes out at to monitor rootzone ph

That might not be dry enough. The pot should feel very light and obviously they’ll drop slightly when in desperate need of some water.

If it’s not watering habits it’s pH related. You’ve got multiple things going on there which is most common when the pH is off. But also the same things happen when the soil is too moist

Watering techniques as stated....water when pots are light, don't bother with the fingerfuck method...depending upon humidity, pot size and drainage and air movement, that dries quickly, while the rootzone remains wet.
Rectify this, problem solved.
Good luck.

Also, get that ph up to 6.7 -6.9....happy soil plants then.
