A lesson for you to study!
Thanks man, great informative video for starting growers. Made kind of a summary if anyone is interested:
“Plants need 17 essential elements to grow and reproduce; 3 of the are free, Carbon, Hydrogen and Oxygen; they come from Carbon Dioxide (CO2) and Water (H2O)”
“Fresh air is very important because the CO2 will be depleted if there’s a lack of air and plants won’t grow to their full potential”
“Plants need full spectrum light; more blue during vegetative and more red during flowering”
“Blue lights will produce during vegetative state a dark green plant, make it disease resistance, short and stalky, and there’ll be more pores that get CO2 in”
“A little bit of ultraviolet light is good because plant will produce pigments, medicinal compounds and antioxidants to protect themselves”
“Don't overwater, because it will suffocate the roots, also it sets up an anaerobic environment”
“Humidity levels should be kept around 40-60% for a successful grow”
“Base Nutrients: Nitrogen - Potassium - Phosphorus - Calcium - Magnesium - Sulfur”
“Nitrogen is the growth element; the first half of the plant growth, it will assimilate about 80% of the Nitrogen it needs for the whole life of the plant”
“Nitrate or Ammonium are the forms of Nitrogen plants can take up by the roots”
“Use half dose for Nitrogen if using mineral nutrients, because it takes about 25 to 30% of the energy of photosynthesis just to assimilate the Nitrogen, it will restrict the root growth and it will affect the flowering process early on, it could delay it and even prevent it; it could cause mold”
“A little bit of Ammonium Nitrogen will quickly fix a Nitrogen deficiency”
“Phosphorus should be upped for first 2 weeks of early rooting and early flowering; it energizes it for better establishment; could take all other minerals more efficiently”
“Oscillating fans are a must for leafs to move a bit and all the time, while recirculating air and helping spread it across”
“During vegetative state, make sure to feed 1.5 times more Potassium than NItrogen”
“During flowering state, at least 2 times more Potassium than Nitrogen”
“Don’t overdo Nitrogen during vegetative state because it won’t”
“Calcium deficiency shows on top of growth because it’s an immobile nutrient, while Magnesium deficiency shows on the bottom of growth because it’s a mobile nutrient”
“A Potassium toxicity (overfertilizing) shows up as a Magnesium deficiency during flowering”
“Add Magnesium when switching to Flowering nutrients because it synergizes”
“Sulfur is another important base nutrient during flowering, it improves not just yield but aroma and taste”
“Enzymes are activated by trace elements like Iron and Zinc, they can produce chemical reactions that improves productivity”
“Yellow leaves can be produced by: Nitrogen deficiency, from the bottom of the plant to the top, pale yellowing of all the leaves; Magnesium deficiency on the bottom of the plant (don’t spray); Iron deficiency on the top of the plan”
