Day 12 Seedlings - Nute burn?

[ThePilgrim]

Problem: New growth tips yellowing. Leaves slight discoloration and droop.

Medium/grow method: OF/EWC/Perlite - 40/40/20. 5 gal fabric pots. 2' x 4' x 5' tent.

Feed: and supplements used: AN sensibloom ph perfect a+b, AN cal-mag. (1st feed at day 10. 1 liter water each plant. 1ml sensi a+b/each, 1ml cal-mag) Will be using @TaNg 's easy auto feed schedule.

water source: Distilled water for initial pot soak and supplemental sprays until 1st feed. 1st feed with tap water. 10 gallons of tap water have been sitting out for chlorine evap for 1 week+.

Strain/age: CK - WW Auto Feminized. 12 days from sprout.

light used: Mars Hydro 600w. Sched: 20/4. Height: 24" from plants.

Climate: Avg RH: 60% Avg temp: 75-79 Small stand fan for circulation. Humidifier in tent.

Additional info: New grower on 1st attempt. After quite a bit of browsing on the forum, I decided to try out TaNg's easy auto feed schedule. No ph tester or adjusters have been acquired as of yet. Hopefully my desire for simplicity in the beginning won't backfire on me.

They’ll grow out of it brotha. I believe that OF is a little hot.

I had a similar problem, but mine got even paler than that. They grew out of it around day 18-20

I agree, it's hot soil. It may not be too late to transplant.

You can mix in/top dress some nute free soil
Leave it alone, hope it does not progress to toxicity
Or you can gently dig them up with roots and all, and make a bathtub in the pot of less hot soil, replant them.

Used fox farms for years, OF to hot for starting, if using ffof, no nutes for at least the first 30 days... I gave up on fox farms recently, their quality control has become an oxymoron...

Happy frog will serve you better for younguns, but check soil pH before using.

... exactly all around guys, thanks! ..... Pilgrim, next time use a different soil, OF is more often than not off-pH right out of the bag, badly so sometimes! Try Roots Organics, Vermicrop, Royal Gold,.... look into getting a quality soil pH probe like the Accurate 8, nothing beats in-pot measurement!

Dr Earth is also not bad... am running it now, 3 bags, all pH'd at 6.4 to 6.6. Not too hot, my Mephisto girls seem to like it well enough, and it was 1/3 less than I paid for my last bag of Happy Frog.

yeah Arthur, I'm hearing more and more positive reports on it,... seems OK for a hugely mass produced soil! My buddy Sniper loves the Flower Girl fert', very nice stuff!... just stinky, which is usually a good sign....
