Yellow leaves on plant! what do i do?

my bottom leaves turned yellow and shriveled, it is a result of not being experience with LEDs. I over watered them thinking ever 2 days it needs to be watered however with LED producing barely any dam heat I overwatered it. I am now drying my plants by not watering them for a week. my question is, what to do with yellow leaves? do i cut the yellow ones off? or leave them.

Prune any that are badly yellowed, they won't recover. Anything that's still at least a third green you should leave. You can cut the damaged portions of a leaf off and leave the green part and the leaf will live on to produce energy for the plant. Also, I wouldn't recommend going a full week without watering, just wait until the top of the soil is dry and crusty and the pots are light. You should be doing that for every watering. You can't just say you need to water every so often because the plants will use different amounts of water depending on many different things, and the water will evaporate off at different rates. Just use your best judgment, you'll get the hang of it.
