Jack's® 7-15-30 Finish Fertilizer is a specialized formula designed to support robust flowering, fruiting, and overall plant health, allowing growers to achieve optimal results during the final stages of their crop cycle. With a carefully balanced composition, this nutrient blend offers a low nitrogen content, high phosphorus content, and an abundance of potassium.

Nitrogen
By emphasizing a low nitrogen content, Finish ensures that plants receive minimal amounts of this nutrient. While nitrogen is essential for vegetative growth, excessive nitrogen during the later stages can negatively impact flowering and fruiting. By reducing nitrogen levels, this formula allows plants to shift their energy towards the production of robust blooms and bountiful fruits.

Phosphorus
The high phosphorus content in Finish plays a vital role in supporting flowering and fruit development. Phosphorus is crucial for promoting strong root growth, enhancing nutrient uptake, and stimulating flower formation. By providing ample phosphorus, this formula helps plants develop healthy and vibrant flowers, resulting in improved yields and overall crop quality.

Potassium
A significant amount of potassium, also known as potash, is essential for various plant functions, including the regulation of water uptake, enzyme activation, and overall plant vigor. By providing plants with an abundant supply of potassium, this formula helps them maintain optimal hydration, nutrient balance, and overall resilience throughout the final stages of their growth cycle.

Note: The amount of dye used in Jack’s Nutrients formulas has recently been reduced to nearly zero. As a result, products that were previously bright blue may now appear white or tan. This color change is normal—no other changes have been made to the fertilizer formula or its performance.

Simply magnificent
Format: Kindle
A new perspective on an old and familiar story. The art is outstanding. The story is compelling. It needs to be a regular ongoing series. DC...please handle this. Thanks.

Probably the best thing to come out of the "New 52" reboot
Format: Paperback
In general, I'm not a big fan of the new 52 reboot of the DC universe. On the other hand, it produced this really interesting investigation of the iffy morality and general maladjustment and emotional fallout caused by the "child soldier" issue of the multiple underage vigilantes in the Batman family of comic books. The scripting for this story is excellent, in that it makes clear the broad range of personalities represented by the 4 Robins, Bluebird, Spoiler, and Black Bat (who isn't named as such in this particular story for some reason), and aside from that the art is really gorgeous. I think this may very well be the best thing to come out of the new 52 reboot.

Don't listen to the negative reviews. There is so much to love in this story.
Format: Paperback
First off, I would like to say that this is mostly for people who either A) bought vol1 and want to finish the story, and B) fans of not only Batman, but also the "legacy" that he has left behind him. More on that later. This is the second half of the weekly 26 week story revolving around The former robins, and deals heavily around The Spoiler, Cassandra Cain (batgirl) and Harper Row (bluebird) the main thing I have to say about this story is that it more effectively does what "batman eternal" and "Robin war" we're trying to accomplish. In batman eternal, the story was over 50 issues long, and there were so many times where the story was abysmal because of filler and boring events that made it feel like such a cash grab, and with Robin war, by the end of that story there is almost nothing important that happens, leaving you to feel like you could have went without reading it. Batman and robin eternal not only tells a captivating story, but with important enough events that justify your time and money put into this story. I can whole heartedly recommend this to ANY fan of not only Azrael (very important character in the 90s when knight fall was going on) but also Cassandra Cain (new batgirl up until 2011) and they in my opinion are the highlights of this story because of the justice they are given as comic book characters. We haven't seen them since in the new earth, so it's nice that they got some recognition before rebirth. Hopefully we see them more, but this is also a solid story for the robins as well, each of Batmans pupils gets justice at some point in the story, so I can say a fan of any of them will be pleased. I can say this especially as a Red Hood fan who longs for the day that Jason Tood will finally get a good/solo ongoing series. Now with that said, the art can be inconsistent seeing as how there are more than one of them, and the "big plot twist" shown in this second half can be pretty obvious that "there's more than meets the eye" with the situation, but I rather not give spoilers. Again This book is MORE THAN WORTH YOUR TIME AND MONEY if you Like ANY robin Like Scott Snyders "bluebird" Like the old ninja looking batgirl Like Azrael Like batman stories that don't have batman as the main focus
