Leaf discolouration…

I am currently growing critical mass autoflower in half happy frog and half ocean forest. I’m running two 100 watt led’s at 30” from the plant. The plant is 24 days old and hasn’t been given any nutrients yet. Any idea what these spots may be?

Look like they might be nute sensitive, if its a 50/50 mix. Tip curl and burn.
It will grow out of it in no time
 
Day 31 and the spots seems to be a bit worse and have spread to other leaves.. there doesn’t seem to be any curling at the tips of the leaves just the spots seen in the picture. Should I give her her first feed now? @Boatguy
