I have four different strains, all from seed. Grown in FF light warrior and ocean forest mix. More light warrior really. I've used nothing but RO water and they are all going into week 3 of veg. My leaf tips are turning down and some leaves are growing odd. What could be the problem?

If it's just the tips turning down could be a sign of overwatering. With RO water you might want to think about adding some cal-mag.

that is a sign of nitrogen toxicity.

a pic would help but if the leaf looks good just the very very tip straight down its usually a sign of a big temp change between light on and off gallery_53075_7151_337304.jpg

That's not overwatering. It is the beginning of nitrogen toxicity. If not addressed it will ruin your grow. Nitrogen can be removed from the soil by flushing.
