RAPID VEGETATIVE: 1 to 2 teaspoons General MICRO (dark)
2 to 4 teaspoons General GROW (green)
1 teaspoons General BLOOM (pink)
This stage starts at about 6 days, or about 6" tall, with the first big fan leaves.
Start at the lower end of the fertilizer dosage, and increase the Micro and Grow
proportionate to the growth rate increases. Use 1 teaspoon of BLOOM the first 4
days of this stage, then discontinue. This stage lasts about 4 to 9 days, depending on
how big you want each plant. If plants are in rapid veg for longer, the plant might
start flopping over from the weight of the leaves. If this happens, add a tsp. of
pink per gallon.
NuFarm General Hydroponic fertilizer is highly concentrated-please measure accurately.
Recommendations are for the high end (optimal) growth conditions, particularly for
short-season varieties. Long season varieties typically need less fertilizer. Overdose
results in browning of the leaf tips about 3 days after application. If plants show
signs of stress, reduce nutrient strength. An underdose would be expressed as yellowing
of the leaves about 3 days after application. If this happens, gradually add more
fertilizer. If this is the first time you've used this fertilizer, probably reduce
recommended levels by about 25% until you get feeback from the plants.
Handy tips: CO2 partially compensates for high temperature and/or low humidity.
The optimum temperature is 76* F, the optimum relative humidity range is 48-57%.
Optimum light intensity is about 4300 foot candles; maximum, 5500fc. With high
temperature and low humidity conditions, use less fertilizer; with high light intensity
and high CO2 levels, use more fertilizer. With optimum temperature and humidity,
CO2 supplementation is not as cost-effective as hydroponics. If you are using real
soil (which has organic nutrients), use less fertilizer. To prevent nutrient build-up
in soil or coco, fertilize every time you water, but every time you water, add enough
(fertilized) water to flush the medium, and discard the run-off water.
