Is there a reason that you are not following the nutrient chart on the bottles of GH? When first starting out, it is recommended to use the ratios on the bottle and then fine tune as you get more familiar with the needs of your plants. I would be giving the plants 1 tsp grow, 2 tsp micro and 3 tsp bloom per gallon. If you are using the Lucas formula with no grow then you should be using a 1-2 ratio with the micro and bloom. The recommended dose is 8 ml micro and 16 ml bloom per gal of water. There are 5 ml in a tsp. So, for every gal you would use real close to 2-1/2 tsp of micro and just a little over 5 tsp of bloom. I also add cal-mag in flowering at a rate of 1-2 tsp per gal, depending on how the gals look.
IMO, a ppm of 800 is not nearly enough for most strains. Even Satori which is very efficient in its nute up, I run at around 1200 ppm.
