Some strains are more affected by MG then others, probably the WR is not liking all the NPK so early in life, remember it"a a Weed..."-)

Miracle-Gro Ingredients ( I believe they use this in there extended release soils )

The All-Purpose Plant Food has a 15-30-15 ratio, meaning that there is 15% Nitrogen, 30% Phosphate, and 15% Potash.

The primary ingredients in the Miracle-Gro powder are as follows:

â?¢ 5.8% Ammoniacal Nitrogen
â?¢ 9.2% Urea Nitrogen
â?¢ 30% Available Phosphate
â?¢ 15% Soluble Potash
â?¢ 0.02% Boron
â?¢ 0.07% Copper
â?¢ 0.15% Iron
â?¢ 0.05% Manganese
â?¢ 0.005% Molybdenum
â?¢ 0.06% Zinc

Compared to Botanicare Pro Grow 3-2-4 & Pro Bloom 2-3-5 that MG in one hot number, not to mention out of wack for the stages of MJ growth...
