Hello all. First timer here...
The auto-girl below is 5 weeks from sprout. She's in a 32x32 tent, 600w LED averaging 30%-50% RH, 65-80 degrees, 18-6 veg. The soil already had nutes so I hadn't ever added anything until, after not being watered for 4 days, and in a hurry, I mixed 1.5 tsp Fox Farms Grow Big and poured 3/4 gallon before runoff accumulated in the saucer. 2 days later, this is what I have. I see brown (Burnt) leaf tips and some leaf curl.
Thoughts? Too much nutes? THX!

Looks like the nutrients are synthetic, time released. .07%-.04%-.03% Derived from ammonium nitrate, ammonium phosphate, etc. Also, processed forest products, compost, sphagnum peat moss, perlite and a wetting agent. I've been watering about every 3rd or 4th day. I'm not going to use it anymore since my FF Ocean Forest arrived!
I'm using OTC all purpose Vigoro potting soil for this one (FF Ocean is on its way for my next, REAL grow!) I flushed it thoroughly and it went from over 1200 PPM to 850. PH meter has not arrived yet!
Looks a lot like overwatering symptoms. What soil are you in? Or is that coco?
Brand new PH meter was DOA...another on order. I'll flush and test PPM tomorrow. Thank you!
Two days is pretty fast for that much nute burn. Need a run off pH and ppm, but also could be heat stress from light being to close. How far from top is light and can you get a pH and ppm run off test?
