Fan leaf stems are red and a few tops curling

am In veg preparing these plants for going outside in 2 more weeks . They go outside during the day from 9am until 6pm . Then they go to a room where it’s 75 and 46 humidity. 75% ocean forest soil with 25% plain #3 perilite . I have them in Geosmartpots . Watering schedule is every 3 days . They are Very dry . Ph is 6.1 on drainage . . I ONLY USE 1/2 the recommended dosage on nutritients . I rotate from flora nova , cal mag , liquid karma , roots excell, hormex and humid acid ....I only feed every other water . In between feeds I use dyna pro-tekt ...plants are growing very fast . I just like them perfect and can’t figure out why some leaves have curled .

Nice plants. I don't see anything I'd worry about. They look healthy as can be.

Your plants look pretty good. I wouldn't chase your petiole color...it could be strain specific, perhaps not, but all in all I wouldn't worry about it. When your plant stems start going purple, then start worrying. As to the twisted tops, again I wouldn't worry about it. You'll probably find that they grow right past this without issue. Steady goes the course; good luck.

Thanks buddy . always need the 2nd opinion

Yeah I certainly wouldn't go adjusting anything in an effort to correct the red stems. You're just as likely to cause a new problem as you are to solve the red stems. But the red stems may just be genetical, it isn't uncommon at all for strains to get purpling stems genetically as well as respond to colder temps with purpling stems and leaf/budmass. Your babies look absolutely beautiful and I have no doubt that they won't dissapoint you in their harvest! Good luck and happy growing!
