There's a few small things worthy of note here. There is a cucurbita plant in the lettuce which shows a severe deficiency. I don't know the exact cause. I believe with some certainty that it is ph/calcium related. I corrected with calcium towards 7.0 and the next leaf shows healthy growth and color. (I also boosted transpiration by adding a fan.) The deficiency in the older leaf has not corrected itself. I've read that sometimes the less mobile nutrients, when corrected, will improve the new growth but won't fix the deficiency symptoms in the older leaves. That seems to be the case here.

Planting multiple species can give a good indication of soil nutrients/ health. Some plants show deficiencies, others will simply grow slower.

Tomato sprout here is off to a slow start... I believe a sterile seedling mix with myco could give a faster start. The advantage of using my own soil is I can learn about my soil problems.

The lights wilt the lettuce at full strength... I'm having to reduce the lights down. I was wrong in my posts last year the white LED is 150 real watts not 300-500, it may only be equivalent to 750 watts in halogen. Both lights together @ 12" is too much for the lettuce (1650 equivalent.). 1050-1350 seems good. They would probably also grow fine at 900. Without a laboratory with good quality testing equipment, I will instead rely on the lettuce to tell me when I've reached "full sun".
