Underfed then overfed, now hows it look?

All that purple coloring looks like phosphorus deficiency. Look at the undersides of the leaves and see if they are getting purple coloration. I can see the leaf veins are. What makes you think they are overfed? None of the leaves are burned. What is your nutrient solution? What is the ph? Are the roots growing well? What is the temperature of the air and water?

Temp can make color changes in stems and branches in veg mode, but its probably more genetics related.
I dont judge a plants health based on branch color though. I stick with how the leaves look all over as this is a better judge of how a plants doing. I also hate to commit to any deficiency diagnosis before I know what the plants being fed.
I also agree with the posters original diagnosis, the plant was underfed and given a booster meal, and now looks like its getting healthy. I would let it ride a few days to see how it goes before making any hastey corrections.
Sprout is right that an overfeed would probably first show up as a yellowing leaftip that eventually browns up.

take another picture of it, of the more affected area
Sorry to hear you plant is sick. Though purple on the stems can mean a phos def during bloom, my blueberry and flo plants always have purple stems. Just look and make sure the new leaf growth is rich green, the damage to old leaves has already been done, and they will remain unchanged for the most part.
I hope this is helpful.

purple stems does not mean you have phosphprus issues, cannabis has naturaly red stems or red hues and colors to the stems,
2.5Gal distilled water ppm 0
10ml Silica Blast ppm 10
5ml of Cal-Mag (before the distilled, i was using my tap with an avg 178ppm)
10ml KL ppm total so far 197
20ml PBP Grow 523
10ml Hydroguard
10ml Senzizyme ppm of 550 (i did not think this would add any)
pH balanced to 5.9
I topped with water until i hit 500ppm.
The cabinet sits right in front of the AC register, so the water temp is normally 68F I figured that is why the stem is purple.
Sounds like you are doing everything right. Thats not alot of roots. They do look healthy. Is the top of the plant cool as the roots? I think I would raise root temperature 5 degrees and have the top of the plant at least 75 degrees or so. I think it will grow out of any problems in a few weeks. I can only reiterate that I see in the picture a leaf with purple veins. Cool temps and limited root growth are probably to blame for a short term phosphorus deficiency.
What is LK or KL? IMO, only add the basic nutrients and the root rot prevention. Doesn't the basic nutrient already contain cal/mag? It is possible to have too much calcium. Calcium + phosphorus = calcium phosphate. This might render the phosphorus not available to the plant.
