I ordered some of the Jacks classic Fert online and it got here yesterday. My plants are about to be 4 weeks old and are starting to fill out nicely. I just transplanted this last weekend.

Anyone who has had any experience with "Jacks Classic All Purpose" and "Jacks classic Blossom Booster" please fill me in on what type of schedule you used and the amount you used. I ordered these as a pair as suggested by others on the forums and by Jacks website. The instructions say that for newly transplanted plants you can start with blossom booster to help develop the roots then switch to the all purpose then alternate after that on and on. It also says I can just use both together.

Does anyone have any experience giving them both these products in combination? I would like to try this.

I know they wont need much. I plan on giving them 1/8teaspoon of each product to 1 gal of water for each watering.

I had great results with "Jack's" when I grew in soil. I never exceeded 1/4 strength with either the veg or the bloom. If I remember right ... I used to use the ferts about every third or fourth watering. You really have to learn to read the plants. It varies from strain to strain, but the plants have a way of "telling" you what they need. It comes with experience. Just be sure to go easy on the ferts ... its easy to burn the plants. The first indication is burnt leaf tips. The tips turn brown. If you see this happening, just flush the plants out real well ... until clear water is running out of the bottoms of the pots.

Did you use them together?

Jack's Classic is my preferred fertilizer.....
I use the Blossom Booster for transplanting with one feeding, then switch back to all purpose.
Assuming your plants are indoors, under 400w minimum, starting with 1/8 is a good idea, depending on how often you water, you can feed every time you water. Gradually increase to 1/4 to 1/2 tsp per gallon, and as Vi says above, observe your plants carefully for optimum dosage. Generally, the more light a plant receives the more fertilizer it can gobble up.


PS. I never used them together; I switch to BB about a week or so after going 12/12
