Enough light for seedling stage?

Like 2 weeks in I start adding nutes and make sure the dosage is low, you don't want to add too much and risk burning your plants. You can always add more if you need that way too.

I added nutes in this morning before the dark cycle and I think she's doing good what do you think?

Use Galatica phone app to measure Lux. You need minimum 1200 Lux for seedlings.

Is there a maximum LUX reading for seedlings?

Sorry to drum up an old thread, but am curious is 6000-9000 Is to much for them at this stage.

I'm a few grower that experienced stretching in my seedlings. I live in Northern Michigan and am experimenting with a few seeds from here. I used a 20000 lumens CFL with 10 watts per seedling, positioned 7" from top of seedlings. Eventually they stretched and fell over. I had to make stem repairs using wet tissue and build up the stems in soft moist used and rinsed coffee grounds. Amazing only they survived and are now on day two of healing. I moved them to 2" from CFL light, lowered temperature to 77 degrees and put light breeze across the floor. Any suggestions?
