NUTRIENT BURN? AK Auto flowering are racing!

Hey guys, I have 2 AKs + 2 White widow in a 4-site tote, they were just moved into here after sprouting. They were given 1/2 nutrients, and 18/6 light cycle. They are coming up on their 1st week in this environment and I noticed some browning/dark green on leaves.

What do you think? Mother's Finest, are you out there? LOL <3



Please check out my journal for more pics and detailed information on the set up.

Time to load a bowl and sit back!

That looks like early Phosphorus deficiency. What did you feed them?

1/2 stength of Floranova's "Recipe for success Starter Kit" veg stage in pure R/O water, Ph @ 5.9. 2 Days later I checked PH and it was up at 6.8, so I lowered it back down to 6. Now its tonight, and I have +gallons of tap water getting aired out for this Friday's water cycle change. Gonna switch to this tap water instead of R/O and probably do a 1/4-/1/2 strength nutrient solution this time.

Keep an eye on the pod leaves. They aren't visible in the pics but if it's fertilizer burn, they'll be in the worst condition.

Ok, will check it out tomorrow when lights on. Hopefully all is well! Thanks for tips
