Spinach and bitter tasting lettuce

My lettuce tastes fine. There is a bitter note to it, but I think most lettuce is bitter.

I know that having the wrong ratio of nutrients can affect taste. This shouldn't be a big deal if you are using AG nutrient mixes. Ph can also impact taste. You shouldn't need to adjust this, but if your water is especially acidic or basic it is a possible cause.

this afternoon I had a LOT of my red salad bowl lettuce on a sandwich and ,to me, it was not bitter at all.But, then again, I am used to eating loose leaf.

I know what you mean. I do think hydroponically grown lettuce has a bitterness level not present in soil grown.  My and my neighbor’s soil grown lettuces are sweeter, for lack of a better description.  I only notice it when it’s in a salad (or otherwise eaten plain), so I add some honey or Splenda to my vinaigrette to try to counterbalance it.  

I use custom seeds, same in AG and outside.  

Must be, I imagine.  Plus whatever the outside lettuce picks up from the soil.

Might think of cheating and supplementing it with some flora nectar, but like I said, that's cheating.

That would be a very cool test.  

YUMMY!

Cheating because it's basically adding sugar to the nutes solution
