Hey so I am am brand new to growing frost time trying but have done alot of research. I'm currently growing bluenana, jeallylicious and frosted apricots in 3 gal cloth pots and using fox farm ocean forest soil and are on day 42 of veg. I'm noticing alot of yellowing on the new growth not sure if it's deficent due to lack of nutes or over feeding . I think I have been over feeding I heard fox farm line is very concentrated and to us small amounts. I thought they were deficent yesterday in day 41 so I feed them 2190 ppm at 6.4 ph. Now I really think I messed up and need to flush because I think my deficency is coming from salt build up in my medium. I believe I'm deficient in iron due to the color and how it's happening on the leaves and only new growth I think I feed to much potassium and now that is locked out a few other things such as iron. I just don't know if I should flush them my soil is still damp from yesterday feeding I don't wanna get root rot or should I let the soil dry more then flush and check my pmm run off ? Please lmk what you more experienced growers think

I do notice the growth to be light green but it's pretty yellow in my frosted apricots and my ppm have been high I'mma do a flush in a day or two and get my ppm to around 500 -600 then let it dry and start a lighter feeding. I also feed them molasses and great white for the beneficial micro organisms and the was my first time feeding them that and I really noticed more yellowing a few days after so not sure if that had anything to do with it or if it's finally just locked out due to feeding to high ppm
Maybe it is in the genetics its my first grow but it looks kinda spotty and it's slowly moving to the leaves below the new growth plus my ppm have been really high in that plant looking back at my grow notes I'm almost positive it's deficent due to lock out
New growth is normally yellow at first and then it changes to green. During late Veg and early flower when the plant is stretching most is when you'll notice it most. You'll also notice it more when the lights just turn on as they have been growing during lights off and hadn't received any light. If it's not due to new growth, then my guess is iron deficiency.
When did you start feeding these?
