Maxicrop but ive noticed that mine is deficiant in nitrogen, i came across some lumpy clumps in the green plastic bottle it comes in and i think it was the nitrogen componannt of it for some reason had clumped up from the solution. but it could just be the maxicrop itself. theres no npk on the bottle, just a feeding guide and use list, ie/ seedlings, planting on/ transplanting etc some other grower may be able to help us out here
