white berry seedlings yellow and burn at leafe tips. 15 days old was on 500 ppm using pro grow from botanicare and liquid karma. i am using RO water nd deliver nutriants via ebb and flo buckets 8 times in 24 hours. 1000 w metal halide. temp at canopy 76 so not a temp. problem. bumped nutes to 800 because i feel it may be a deficiency leaves are not as dark green as they should be and i see purpling in the petioles as well as purple specs in new growth.

any feedback appreciated maybe i need cal/mag?

Hmm sounds more like a nute burn than deficiency. I am sure they are to young to be feeding already. Well that is if they are 15days from sprout. If it were clones I think you should of been ok. Just my 2 cents.

post pics always easier if we can all see the plant for outselves that is a great thread hope it works out for you.:blsmoke: https://www.rollitup.org/marijuana-plant-problems/216537-self-diagnose-your-plants.html
