Back again.. With the plants that were spotting..

Before & after photos a wk later from my initial concerns and problems. First 4 are what I was concerned with last wk.. someone said it was the start of nutrient lockout. I use soil and never added nutes until this wk. 3 days ago I repotted added new soil & gave some cal mag. With the watering. The last few pics are today and some old foliage that I think was dying. It’s only the bottom leaves turning yellow. I’ll also add some photos of the whole plant.

Plant update since the spotting. Some plants turned more yellow at the bottom. I re-soiled & red potted to add nutes back into its life since some suggested it was starting to nute lockout.. I’m at day 56 since planting the seed

Its normal that lower leaves that catch lower lights turn yellow in time.
It's a "weed". It grows exuberantly, and then it don't mind the oldest leaves that get little light.... it mobilises the nutrients of them and goes on. I dont think this is a problem

These plants look great. The deep green color tells me that it has enough Nitrogene, is good fed.
The top canopy seems to grow rapidly, big leaves I see.

Youngest expanding/growing leaves in strong light usually appear not that dark.
All fine here IMHO.

Thank you! I had some brown spots starting which would make sense that the plant would start to lock out since I only have been using soil. So that’s why I went ahead and reported it’s been at least a month or more since I did my first transplant. So I can assume all the nutes have been used. She’s really tall like really close to my lights now. Thinking about flipping the switch sometime in the next few days or next wk. just not sure if I should wait a wk since I just transplanted this wk or just go ahead and start the flower. I’m at day 56 since I popped the seed in. About 50-52 days since the seed broke surface. Also not sure if the soil will affect the nitorgen intake for the plant in the flowering stage?
