Please someone help! Leaves are Yellow!

pictures always help..but it just sounds like normal bottom leaves falling off because they arent getting enough light

some bottom leaves will naturally turn yellow and fall off, but if the yellowing moves up the plant it's most likely a nitrogen deficiency. what kind of oil are you using?

what kind of oil or soil? If soil I am using a type of organic sea soil which came with the kit I had purchased. The yellow leaves rnt that bad they r only on the bottom of the plants but I am a bit nervous. If it is light is there a way i can provide efficient light to the lower leaves without burning and can over watering be a problem causing this? I have only had the plants for about a week and they look good nice size and color just the lower area is kinda dying off.

im sure the problem is simply that you are giving them nutes period. the soil mix you have probably provides them with enough nutes for about 4-6 weeks so if they are that age or younger that's probably it.
if they are older its just because the plant is naturally losing its bottom leaves so dont worry if that's the case.

Flushing was the wrong thing to do now they will probably get even worse, they needed more nutrients not less.

If the yellowing gets worse which it probably will now AND the leaves don't show signs of burn (curling tips downward or tips turning brown) then give it a stronger mix of veg nutes. Nitrogen deficiency...
