60 Day Lemon Auto DWC

Sorry I didn't update earlier. This plant is growing good. There are 4 nodes with a 5th appearing now -- about the time I'd usually top my plants. Since this is a ~60 day strain, I'm not going to top this one. Plus, I have very limited space in my 4x4 tent. I have two plants in there that are a few weeks away from harvest, so they're hard to control! This plant is healthy, though today I noticed it looking a bit yellow. Could be because it is struggling to get light, the lights are too far away (other plants would be too close), or my nutrients need to be swapped out. I am going to try a nutrient swap today, and will keep it around 250 PPM. I may actually mix half veg nutrients, and half flowering nutrients. With such a short lifespan, this thing has got to be switching to flowering soon! I ALWAYS APPRECIATE INPUT, SO PLEASE THROW YOUR IDEAS AT ME! UPDATE: I had what I thought was slight yellowing of the leaves. I'm an idiot -- it turned out to be the way my LEDs look coming through my larger plants nearby. So it was essentially shade vs light. Thanks for everyone's input! I boosted PPMS to 350, and had no issues. Glad to give it a higher level of nutrients. I removed the top feed on day 20. Roots are healthy and robust enough that it likely won't make a difference if I top feed anymore.
