Do any of you grow with LED’s through the winter? I unfortunately have NO natural light indoors so they must strictly be grown with artificial lighting.
Note I use pretty powerful lighting, in order to replicate full sun, however, as you can already guess, nothing can truly replicate Mother Nature. My plants always start out great and grow well for the first month or so, things start to grow yellow and stressed. I typically keep my lights around 75% (noting that 100% really stressed them out) and on for 14-16 hours, off the rest. I feed them properly and meticulously with a very well balanced fertilizer. I would like to see if anyone else has these sorts of issues and how they go about correcting them before things are needed to come indoors.
The lights I use are a mixture of high output sonofarm LED’s. Links below.

https://sonofarm.com/product/sonofarm-spider-farmer-sf4000-led-grow-light-full-spectrum-samsung-lm301b-diodes-meanwell-driver/I just recently moved these trees outdoors after sitting a month or so indoors under these lights.



The same varieties outdoors show no signs of these, and are treated the same otherwise. Are these lights just too much? Can water pH do this? (Ones outside get some rain water obviously along with the hose) as I am on city water. Anyone recommend a good way to test soil pH?
Any input on this situation, I’d appreciate it! Winters are usually incredibly hard, hoping to get through this next one without as much loss. Prepping is key! Lol.
