This feeding schedule will help you on your new adventure of growing high quality marijuana. These ratios are based on a medium consisting of a semi-soilless mix of 1/3 Super Soil (a generic soil brand from Home Depot), 1/3 perlite & 1/3 vermiculite. Supersoil contains no nutrients, so if using a different brand w/ nutrients adjust your fert amounts accordingly. With a soilless mix, approximately 1/4 of the water going in has to be runoff, to wash out the salts from the last watering & any build-ups. It is very important to check the PH of your runoff water also. For example, if it is going in at 6.2 and the runoff is 6.8, you have a salt build-up and have to flush your plants w/ PH adjusted water & then check runoff. This is very important, because at higher or lower PH levels plants will take in more or less of some nutrients. Use good quality water with a PPM of less then 150. When using GH Flora series always mix your micro first, stir well, then add your grow, stir well, then your bloom, again stirring well. Failure to mix your micro first will result in certain nutrients being locked out & unavailable to the plant. Measurements are given in teaspoons per gallon using GH Flora series.
SEEDLINGS (Day 1 - 14)
During this stage your plants need no nutrients. Plants have enough energy stored to last them roughly 2 weeks. I've seen many grows ruined because people killed their plants during this period.
VEGETATIVE GROWTH (Day 15 - 45)
Early - 1 tsp (5ml) each - micro , grow & bloom. Adjust PH to 6.2
Middle - 1 1/4 tsp (6.25 ml) micro, 1 1/4 tsp grow, 1 tsp bloom. Adjust PH to 6.2
Late - 1 1/2 tsp (7.5 ml) micro, 1 1/2 tsp grow, 1 tsp bloom. Adjust PH to 6.2
FLOWERING (Day 46 106, more or less depending on strain)
Early - 1 1/2 tsp micro, 1 tsp grow, 1 1/2 tsp bloom. Adjust PH to 6.2
Middle - 1 3/4 tsp (8.75 ml) micro, 3/4 tsp (3.75 ml) grow, 1 3/4 tsp bloom. Adjust PH to 6.3
Late - 2 tsp (10ml) micro, 1/2 tsp (2.5 ml) grow, 2 tsp bloom. Adjust PH to 6.3
Later - 2 1/2 tsp (12.5 ml) micro, 1/2 tsp grow, 3 tsp (15 ml) bloom. Adjust PH to 6.4
Always remember to water your plants w/ plain PH adjusted water the last 2 weeks to wash out any built up salts & to try & reduce the chemical taste that unused ferts leave behind in the weed. The plants used in this example were grown using a 400 watt HPS. If you use this information & have good genetics, I guarantee you will have a good amount of high quality weed in 3 1/2 months. Peace
