Purple stems

So I’ve noticed on my bigger plant that the stem to the leaf is turning purpleish on like 2 of the leafs and so I thought it was just the strain I’m growing (cherry pie) but I’m now starting to see it on my other 4 plants that are about 2-3 weeks old anyone have any ideas or suggestions as to what the problem may be??? Should I just let it grow and see if it continues I just started using FF nutrition on them yesterday but I noticed the problem a few days ago

Are they clones? I grew 4 cherry pie outside last year. Pretty much all the stems on them were purple already when I picked them up at about 10 inches. One of my favorite strains btw:bigjoint:

It completely normal for CP too purple early. The buds I grew of it finished with a very heavy GDP influence. Dark green and purple nugs. Pure Heaven:weed:

could be a phosphorous problem, but that's actually pretty rare. more likely it's either genetic and its just a coincidence thats its happening to different strains, or perhaps your night time temps are a little low, and thats causing it. night temps shouldn't be more than 15 degrees lower than day temps. i wouldn't worry about it unless you start seeing leaf damage consistent with P deficiency
