snip it from an article. 315W is the most popular size for LECs/CMH grow lights. Both the 315 LEC and 315 CMH grow lights should be kept at least 18″ from the top of your plants, with some models needing to be kept as far as 3 feet away. https://www.growweedeasy.com/how-far-grow-lights#lec-cmh-grow-lights-distance-plants I would suggest consulting the manual for your unit. See if their are any generalized PAR light maps for your model as that will give you a good idea for the height it needs to be hung. If this info does not exist ask the company for technical data on it, they should be able to provide something. best of luck

What pre feed is in your soil? I did not see any nutrients in the diary? They should not need any food just yet unless the medium it started out in depleted. Some autos will also just be picky and grow a few inches and bloom. But I have found they do not like a much feed as Photos and are more sensitive to high stress training/transplanting and only gentle LST should be used on them. The dark green on the leaves suggest its getting enough nitrogen and and yellowing may look like hungry but I don't think it is. If anything when its ready for feed use less. Also last note, I find with autos being so picky they like soiless more so then soil, but this could very well be my own bias. I can only speak from my own experiences.

I just checked your diary. The yellowing of the seedling leaves is of no concern at this age, often the first few sets of leaves can be "funny" as the plant establishes itself and I would definitely not feed or worry about the leaves at this age of your seedlings, they will work themselves out and get going soon enough. However, growing autos and photoperiod plants in the same tent is going to pose problems, your photoperiod plants will not flower at 18/6 and your autos will not perform very well at 12/12. When it comes to tent growing, it is all autos or all photoperiod plants and never mix the two, otherwise one is going to lose out, sorry to say.

Filling the grid then flipping to flower is the idea. Just keep everything horizontal and once the grid is full, go to 12/12 and be prepared for some serious stretching. With this awesome strain, you may have to go to 11/13 to get her to finish flowering and tame those Sativa reflowering genes!
