Flora feeding schedule for soil growers

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 6.4Always 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.

    Yes I have a hard time ph I use ph up and down and sometimes I might have a ph of 7.3 and put a ph down and I get and ph 4.3 using an eye dropper and just one drop so then I will use one drop of ph up and it will read 8.8 or at her times like tonight I was at 5.9 and wanted 6.2 and I would add 3 drops and it would not change that very frustating to me. I never been able to ph I alway have a problem with it going to high or low or keep adding it and it does not change.. can any body help me with this problem because I am alway having nutrient difiencey.and also I am takeing Roberts lab course and they have a feeding schedual for the flora nutrient and he say to use at 1/2 strength and it dose not call for more then 1 teaspoon per gallon or less

      it’s very important to have a very good ph meter. once you do, you shouldn’t have problems adjusting ph to the desired level..

    the measure per gallons is for the pot size or just a ratio of water-nutrient?

  • Edgar
