My first year using this stuff, ill also be feeding them Pure Blend Pro veg formula every 7-10 days or so. Will this be sufficient? What else can I do?

Thanks in advance!

It's time released, I'm not interested in that. I like to know what I'm putting in each time and not when the fertilized decides to release, heavy rain can cause it to release faster and all kinds of probs

its the best, if you want quality nutes right up till harvest use osmocote. Dont mix it with the soil only top dress as this slow release fert only activates when weather is warm not when wet. All you need is a handfull around each root zone anymore is a waste and at $180 for 20kg you dont want to waste it.Try to get the 3-4 month not 5-6.

Formulated in the mid 60's, Osmocote has been available in several formulations/ratios for decades. Each fertilizer prill is coated with resins that allow a "controlled release" of macro/micronutrients. The resin coatings are semi-permeable to moisture but, are also temperature dependent. During cool weather, when most plants have little need for large amounts of fertilizer the release is extremely slow. Several different thicknesses are manufactured thereby permitting different ratios of slow and fast prills to be mixed together. The technology is a bit dated but has been the standard of the nursery/container grown industry for many years. I've used it on outdoor grows several times with excellent results.
Since the release is very gradual, it is ideal for a grower that wants to limit their exposure (and overall "fussiness") to their grow patch. Basically, you can incorporate a small amount of this product in to the native soil on the day of transplanting and forget about fertilization requirements through the rest of your grow. The release of macronutrients is so ponderously slow that there is almost zero risk for fertilizer "burn". Unless of course if one fails to read and follow the label directions. Compared to the incredibly expensive "organic" fertilizers for sale at your local grow shops(complete with trippy, colorful graphics) it is hands down one of the easiest ways to feed your plants cheaply and effectively.
