not exactly sur ewhat the "starter nutrient charge(with gypsum) is but sounds like it already has come kind of salt based nitrogen in it. so yeah im going to stick with the flush and 1/4 str nutes after a week. its probably a burn.Sun Gro Horticulture has long set the standard for the industry to follow in professionally formulated growing mixes. They formulate their mixes to give consistent results in every bag and bale. Mix #4 is recommended where high air capacity and fast drainage are needed with water and salt sensitive crops, or where frequent leaching is required. Ingredients: Canadian Sphagnum peat moss, coarse perlite, starter nutrient charge (with Gypsum), dolomitic limestone & long-lasting wetting agent.
still test that PH it is important
also does sound like this stuff may dry out fast, i dont know from esperience myself but definatly keep an eye on the moisture levels. they do make a moisture meter you can insert into the soil if it becomes that much of an issue but by lifting the pot right after watering you can then just pick up the pot and compare how heavy it is to the amound of moisture in the medium
