My White Widow was at 1400ppm in veg cycle and its currently at 1400ppm in the first week of flowering. The plants are about 5 weeks old. There is no sign of burning. A smaller weaker plant will not be able to handle the nutes of a larger and healthier plant. So depending on your plants, nute accordingly. Its obviously always better to error on the light side of things first time around.
