Hey man, download the tent buddy app (this link is for android users) but it seems more accurate than photone. Iv used both. I like the tent buddy app better.
Your plant is basically saying that youre giving it too much light. But i see a lot of spots on the leaves, and yellowing from the edges inwards.... probably some kind of deficiency? Calcium/magnesium?
Personally, i would cut the light by about 30-40% and see if that makes any difference. Shes in flower so i wouldnt wanna cut way too much, and the foxtailing could possibly be caused by other factors as well so just another reason not to over react on the lighting lol but worth trying a small change for a bit to see :)
Hope you get all the help you need dude! Im in the final stretch with ya!
