Critical Orange Punch - First Grow

could the phenotype, i actually got 7 of them 6-7 week into flowering, one is 88cm, 5 are around 100m, and the last is over 1m20 and topped thats 40 cm diff between the pheno, so could be a smaller pheno

have you heard of VPD ? not getting perfect VPD is the only reason i see for this result, lights are fine, distance is fine temps are fine, if VPD is not fine could be that. That or training. VPD is what regulates the metabolism of the plant, metabolism is what makes the difference in terms of growth and maturity. VPD = vapor pressure deficit , some sort of ratio between the temperature of the grow room, the atmospheric pressure, the temperature of the leaves and the humidity. Here's a chart to help you out : http://www.just4growers.com/stream/temperature-humidity-and-c02/vapor-pressure-deficit-the-hidden-force-on-your-plants.aspx hope this helps ! 🚀

Mainly two things. You vegged too little time or you kept the light too close, which will keep the plant miniaturized. Each LED is different, but if it's really 600 real watts, then try a distance of 45 to 60 cm. Another important thing is to fill the whole area and keep the canopy flat, which will help your yield.
