It was in a small like 2 pint planter. Organic soil. It had one 60 watt 1,200 lumen blue spectrum blulb on it. After about a week out of the soil I put three bulbs. One 60 watt 1,200 lumen blue spectrum, one 150 2,000 lumen watt blue spectrum, and one 150 what 2,000 lumen yellowish (soft white) bulb. The bulbs were about 6" from the plant and I had a small fan blowing on it. I added no nutes at first. Since then I was informed that the soil seemed compacted, so I mixed 30% perlite with the same organic soil and put into a one gallon planter. I originally had all three bulbs still on it at the same distance, moved it to a 18/6 timer. I added 1/4 the amounts of nutes specified to a gallon of distilled water and would spray about three solid squirts around the roots of the seedling every other night before the night cycle. I just noticed the yellowing yesterday. Today I switched it to just the 150 watt 2,000 lumen blue spectrum in a 10" reflective dome placted about 2" from the plant so it's right on top of it. Same 18/6 schedule, I figured this was actually getting more light and more heat to it. They are all CFL lights so heat isn't really too much of an issue. What's the deal with the yellowing, help me please. You can see the little trichromes (is that what they are) if you zoom all the way in. Pic 4 is the orignal setup in the small planter, it's in the large planter in all the others. Pics are super high res.
