One of my plants bottom leaves are turning yellow with dark spots. This has been happening for a while and the bottom set of leaves has fallen off already. I attached a picture of what the problem looks like. I wouldn't want this to spread to the rest of the plant or my other plants.

That does look a bit odd, but it's not uncommon for the early plant growth to die, this happens in most plants. I wouldn't worry about it unless it spreads throughout the plant.

It appers to be spreading upward slowly to the rest of the leaves.

do you spray nutes directly on to your plants? if you do stop. or.....it may be a lack of phos. weird pic its hard to tell

damm that looks nasty...ive never come across yellow leaves with black spots and buy the look of it i think its spreading to the rest of the plant. The green leaves on that plant have black spots, so def spreading.

I dont think it has anything to do with early growth. Are you spraying somthing on them?

this was occuring from the begining on two of my early plants. I pulled off the bad leaves hoping it would stop this, but it apparently hasn't (first 2 nodes dead). My other plant is experiencing similar symptoms but on a smaller scale. Also this had been happening before i added nutrients, and it has not appeared on my other plants (yet?). This is only appearing on the bottom most set of leaves.

Look closely, are they little bugs or black spots actually on the leaf. Looks like an entire army of spider mites, sucking your plant yellow. I could be wrong.
