Battling some light burn or potassium deficiency. Given she has received PK booster twice recently I'd say it's light burn. I've moved her down maybe 2 or 3 inches to see if the burn stops. Will continue with 1g/L bloom and bump up from 0.1g/L to 0.2g/L PK boost this week. I will keep using PK boost until I see burnt tips.
Day 6 gave it some seedling nutes only 170ppm to ease her into it. She's also been ramped up to 20/4 from 18/6 today. Mars Hydro 300W (drawing 135W) at about 24". 170ppm in and abour 350ppm out. 6.5pH in and 6.3pH out.
Looking good! Anything above 20c is fine looks indicate by the wide shape of the leaves they can usually grow fine above 16c. Trust me from experience where I live it gets cold 😨
