Dirty's First Grow

I was out of town from 2/19 to 2/22. I watered my Pot slightly before leaving. Since it was Transplanted about 5 days before I left I felt it was fine with water. My wife was checking it every morning and evening for me. She did add water a few times but only enough to really wet the top layer of soil. I gave the plant 1gallon of water this Morning 2/23/24. 2/27/24 - Today I checked on my plant and saw it is growing its 3rd node. I plan on topping 3/1/24. I also am mixing my veg juice tomorrow. I think ill be watering the plant Saturday 3/2/24. My plant has some yellowing on the new growth. I am not sure if this is because of needing nutrients or if its normal for the fresh growth to show a little yellow. The camera make the yellow stand out way more than I can see with my naked eye. I cant feed nutrients just yet as my soil is still pretty moist. I also removed the Dome on the plant as its getting too big for it. My humidity is a little around 43 percent and Temp is 82 most of the time in my tent. I am hoping the removal of the dome will dry my soil out a little faster for my feeding.
