Let's Do Some LST

    Grow Goals Week 8 of Flower ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ 🌦️ VPD of 1.2-1.5 kPa for Late Flower 🌙 Diurnal Temp Difference of 10°F / 5°C 🌦️ Minimum Air Movement 0.8 m/S ⬇️️ Decrease RH to 45%   🔆 Maximum Light Infiltration 🔆 Maintain DLI at 40 (Daily Light Integral) for Late Flower   🚫 No Mycorrhizae 🚫 No Microbes 🚫 No Sugars ⬇️️ Reduce All Nutrient Concentration by 20% Every Feeding   🚜 Remove Yellow Leaves 🚜 Defoliate Anything Suspicious   🔎 Pest Inspection 🔎 Mildew Inspection 🔎 Plant Happiness Inspection 🔎 Trichome Watch (20% Amber / 80% Cloudy) ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾          🌦️  Humidity    ‾‾‾‾‾‾‾‾‾‾‾‾‾ I have the Lung Room RH below 50%, but the tent continues to have slightly higher readings. I suspect outside humidity is being pulled through the flooring, but for now this is enough for harvest. Below are the danger zones for powdery mildew and bud rot.     Powdery Mildew   RH - 62%+   Temps - 77°+ / 25°C+     Bud Rot   RH - 85%+   Temps - 55°+ / 12°C+   I will be investing in the cheapest vinyl flooring available for the entire lung room. This will prevent outside humidity from creeping in and also keep spills from soaking into the wood floor.   Since I cannot meet my grow goal of 45% within the tent, I have defoliated many of the leaves to increase air flow and prevent humid microclimates from forming.         🚜  High Pour-Through Readings    ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ My Pour-Through EC readings have been rather high. I will be flushing this grow instead of reducing the nutrient concentration. Long term, reducing nutrient concentration will remain a grow goal.    For my next grow, I will be monitoring and responding to the Pour-Through readings from the start. This will prevent over feeding or having to flush.   See week 14 for details on the Pour-Through method.       🔎  Trichome Watch    ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ No amber trichomes yet.       🔎  Pest Inspection    ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ No signs of pests during my under-leaf inspections or sticky trap monitoring.       🔎  Nutrient Deficiency Inspection    ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ One thing I am watching for during flush is the condition of the sugar leaves on the buds. Dead sugar leaves are a pain to trim and can affect bag appeal. So far, my sugar leaves are looking good.        🔎  Plant Happiness Inspection    ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ Possible fox tailing for one of the strains, but with one week left I am not going to spend resources looking into this.      ___________________________________________________________________________________________________________________________________________      Fabric pots to prevent root binding.   I am taking the Syn-ganics approach. Using soil with microbes + mycorrhizae added to the nutes. Mycorrhizae will be phased out during flowering as the high phosphorus environment halts fungal germination (Teaming with Fungi: The Organic Grower's Guide to Mycorrhizae by Jeff Lowenfels)   Enzymatic (Sensizym) will assist in breaking down dead root material in the soil. Any brand enzymatic that can break down cellulose will do just fine.   Agsil16H Potassium Silicate is pre-mixed at 148g per 1 gallon of water. Silica will aid plant strength/structure and also make the plants taste terrible to pests. As a side note, plants with too much nitrogen input taste sweet and delicious to pests!   Bacillus Thuringiensis subspecies Israelensis (Bti) (aka Mosquito Dunks) solution is added to the nutes to kill any larvae based pests such as gnats. Mixing Mosquito Bits into the soil is also a great idea.   Seaweed Bottled Mix Ingredients (NOT an endorsement. I purchased this with my own money) ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ - Ecklonia Maxima Kelp - Fish Hydrolysate - Blackstrap Molasses - Humic Acid / Fulvic Acid - Select Amino Acids (L-Alanine, L-Arginine, L-Aspartic, L-Cystine, L-Glutamic Acid, L-Glycine,   L-Histidine, L-Isoleucine, L-Leucine, L-Lysine, L-Methionine, L-Phenylalanine, L-Proline,   L-Threonine, L-Serine, L-Tryptophan, L-Tyrosine, L-Valine) - Calcium Phosphate - Arcanite - Sugars - Yucca Extract - Tryptic Soy Agar - Plant Hormones, Plant Growth Stimulators and Vitamins (Auxins, Cytokinins, Gibberellins,   Abscisic Acid (ABA), Adenine, Indole Acetic Acid (IAA), Adenosine, Zeatin, A (Carotene),   B1, B12, C, D, E, K, Biotin, Niacin, Choline, Pantothene, Folic Acid, Folinic Acid) ________________________________________________________________________________    I Build My Own Custom Grow LEDs https://growdiaries.com/diaries/165481-grow-journal-by-negotiatedbubble   Custom Built Modified Grow Tent Frame https://growdiaries.com/diaries/165474-grow-journal-by-negotiatedbubble   Custom Built Watering Table https://growdiaries.com/diaries/165482-grow-journal-by-negotiatedbubble   VPD Chart and Calculator spreadsheet https://docs.google.com/spreadsheets/d/1Dta8AptwIIgo728nAu4l9acrWYWPdrljjV4uzXwGJ0Q/edit?usp=sharing   My Custom Nutrient Spreadsheet https://docs.google.com/spreadsheets/d/1grolLVrJLQVSdK7sdnR7dS86axWIzDgW1iWWZIFHhiA/edit?usp=sharing
