Two of my plants are not doing fantastic, and one is effected mores. I'm noticing white and brown spots on the lower leaves, and yellowing.
I've added epsom salt to my watering, because I thought it was mg deficiency. But I'm concerned it could be pests, such as root aphids or something on the leaves. Here are the pictures, this is about three weeks in.






The single plant is the one I am worried most about because the problem has moved from the very first botoom true leaves to the second node.

"Started from the bottom now were here!" Haha jk
Isn't this just a simple Nitrogen Deficiency, it's like a textbook yellowing.

I get the feeling it might be N deficiency also, your plant looks a little pale to me.

Good question, I've wondered this myself. I do have purple streaking, and taco leaves which are both signs of magnesium deficiency.

If you are using fish emusion just go with a 1/4 dose it is hard to burn plants with fish emulsion. I used it on my first grow and started out at full strength and never burned my plants and they weren't much bigger than yours
just a little side note in my opinion if they are showing nitrogen deficiency they are big enough to start feeding because they are using up what they have and telling you they need more.

Looks like nitrogen def and the lower plant isnt getting enough light.
What r u using for lighting and whats the height from the top of the plant?

The soil I'm using has ferts in it. Could this be a case pH lockout?
The clear consensus seems to be a nitrogen deficiency. The nutrients in the soil run out at some point, and your plants will need to be supplemented with more food. slim83 is absolutely right, that when your plants start showing signs of a deficiency, that means they're hungry. Seriously, try adding a bit of nitrogen.

pH lockout caused by lack of microbes breaking down the nitrogen into something the plan can use as food would cause a deficiency as well.... This soil feeds for 90 days. they are 3 weeks old.

So, what's the fastest way to save them? I gave them SUPERTHRIVE, nut it only perked them up, didn't stop yellowing. What's the most cost effectice nitrogen supplement?

Go to nearest Box or garden store, to the garden dept....
Buy a NPK fert with a high N #
Read the label
20-10-10
so that would be 20N-10P-10K
any thing or type will do that mixes with water, don't get spikes or jobe sticks...
Get a water soluble NPK, and use as dirested...
Good Luck

A pH lockout would likely cause other deficiencies as well, which it doesn't appear you have. This is a good thing, with a simple fix. Sand's got it.

Cheers, good luck and happy growing!

How long after applying food by directions, should I expect them to green up again? So far they are not wilting, but stil yellow.

Depending on how extensive it'd gotten, the old leaves may not get any better. But even then, the new growth will show improvement and other old leaves won't be affected. Happy growing!

Whenever I have had non pest related trouble in the past and waiting it out doesn’t resolve the issues, I find the fastest way to save plants is to re-pot them into new soil/compost, this not only reverts your plants back to a normal NPK and PH level but also gives you the opportunity to inspect the roots and smell the soil for molds.
