Yellowing leaf tips on a young plant. Pics included.

So I've got these AK-48's and they've been doing rather good the entire grow. Recently one of the plants has shown some yellowing leaf tips.

1.5 Gallon pots, 20 days old from seed, just in miracle grow potting soil mix and some shultz potting soil. Transplanted twice.

Hoping for a diagnosis, kind of baked...

Here are the best pictures I could muster;

Cheers.

This problem is still persisting. I've added 4 tablespoons of bat guano between all of my plants recently to see if a low PH or nitrogen deficiency was the problem, as a lot of sources are pointing towards these. Not much progress yet.

Still some yellowing tips appearing, though growth continues at a steady pace of 1+ inches a day, day 23.

tip burn/nursery burn usually means you're feeding them a bit too hot. back off a couple hundred ppm and it should stop.

Thanks man. I'll cut back on bat guano. Maybe throw in a couple filtered waterings.

if its nute burn u should flush em then wait couple days and feed em half strenth! that should help.Good luck!!

well i just reread what u wrote..and u said u were using miricle grow potting soil! what u have to remember is there food already in that soil and when u water them those little balls break open and release food and then u add more food which causes burning.. that why people dont like using miricle soil cuz they cant control it as much! im no expect but i learned the hard way haha!
