Not if it occurs within hours of adding nutes...
Soil, seedlings with first true node, following Big Bloom feeding schedule, 1/2 strength. The chart says to begin with seedlings or clones, as it aids in root development. Within 4 hours, it was evident and plants were heavily flushed. Only lost one, but the rest are stunted and still recovering..... It looked like heat stress, but the HTG person insisted it was the freshly added nutes. It was the first Nute watering too, so I have to go with that....
That was part of my problem as well. I use MG Organic Choice TM soil and I amended it with worm castings and perlite. The soil has enough organic food in it to get through veg easily. I'm beginning to wonder why I even bought a tri pack of nutes since I can't see myself using Grow Big with my soil... I may have to sell it on eBay or save it for possible N deficiencies.
I used Ocean Forest for this round because it was easy and quick. I usually do my own amending and OF is nearly the same from what I can tell. I won't even mix in 1/2 of the reccomended dose of BB until a couple weeks or so after I start the feeding. Even then unless the perticular plant NEEDS the food, it can still be too much in some circumstances. I'd rather have something of that high concentration than something I go through more quickly any-how.That was part of my problem as well.

But to anyone that says you can't burn plants with BB, I'm proof positive that you can...
Actually, I can see where you could if you are using it on seedlings that young. I follow the FF schedule, except I start in on it around week 4 of vegging. You don't need any nutes of any kind for the first 3 to 4 weeks in most decent soils.
