    Roots Organics Dry Amendments Bat Guano / Phos Rock

    Thank you for the replies. Very helpful. I will have to take it up with the distributor why they are advertising 1-14-0 product and shipping a 0-9-0 product. Sounds like the ole "bait and switch" to me.

    Roots Organics Dry Amendments Bat Guano / Phos Rock

    Is anybody familiar with these Roots Organics Products from Aurora Innovations. I ordered a product called Super Phos Bat Guano. It said the NPK was 1-14-0. A distributor sent me a product called Super Phos Rock with NPK 0-9-0. This product says it is derived from Phosphate Rock, not bat...

    Phosphorous deficiency

    Liquid Bone Meal - not sure if 100% organic - I don't care much for certification labels. Herculean Harvest is 0-6-0 GH pH down is phosphoric acid based - not organic - can only use citric acid to lower pH in organics IIRC Since Certified Organic Cannabis is not a thing in my closet, I don't...

    How To Design Foliar Sprays (Summary) John Kempf AEA

    What I have been trying to learn up on is the reproductive process of the cannabis plant. I guess they call cannabis fruit an achene. Each [what people incorrectly call] calyxes are actually bracts. Each female flower has a single ovule, which is encapsulated by bracts. Each female flower also...

    How To Design Foliar Sprays (Summary) John Kempf AEA

    I have the advantage as a new grower that I don't know any better. I experiment with everything. I foliar feed often. 3, sometimes 4 times a week. Its the third week of flower and I foliar sprayed back to back nights. Including the young nuglets; they get sprayed too. I hit them once with a...

    How To Design Foliar Sprays (Summary) John Kempf AEA

    AEA says chelated Calcium can be applied via foliar as a band-aid. Unchelated Calcium will not travel through the plant and should not be used as a foliar. Many times Kempf says its important to have the calcium in the soil so it is uptaken though the roots. And for soil applications...

    Fox Farm Ocean Forrest is giving my plants nute burn

    I saw Logan Lab M3 test results from 2 separate bags of FFOF and one of Happy Frog. Not sure it will help but I think the info is relevant to the discussion. One bag of OF was 5.6pH, the other was 6.6, and Happy Frog was 6.3. OF had total exchange capacities of 12.2 and 9.3 Means one had 33%...

    R:G:B ratios for different Kelvin White LEDs

    Thank you pulse meter pro seems to give me exactly what I am looking for. I use a doctor meter lux meter, not a par meter. I took PAR measurements off a YouTube channel review of my light and then measured in the same fashion with my lux meter. Lux or lumens or whatever divided by 60 gives me...

    R:G:B ratios for different Kelvin White LEDs

    Let’s say I add some red. Or Blue. That’s not a quantifiable addition unless I know what I started with. Thanks for the input, but am only looking for specific numbers, so I asked a specific question. Only interested in B:G:R ratios for different K temp spectrums. Not interested in how to crop...

    R:G:B ratios for different Kelvin White LEDs

    Just want to know exactly what is in the spectrum I’m giving them and how I would need to alter the number or type of led to tune the spectrum. I might pick a different light that has a different mix of LEDs. I’d like to be able to look at the specs and say ok, this light is 50% red, 20% blue...

    R:G:B ratios for different Kelvin White LEDs

    My current lights have... 180 Samsung 3000K warm white LEDs 92 Samsung 5000K white LEDs 15 660nm deep red LEDs 1 730nm IR LED Is still like to know how much Blue vs Green vs Red is in a 5000K and 3000K spectrum. I want to be able to say “I’m giving them 20% Blue (300-400nm) now but want to try...

    R:G:B ratios for different Kelvin White LEDs

    So what I was looking for was integration of those curves. What Calculus?, I know... But calculus is what gives the answer. To answer my question, you need to measure the area under those curves. How much area under the curve between 400 and 500nm, area under the curve from 500-600nm, and then...

    Sulfur?

    I’ll try to raise them up but I don’t think it is light stress. I’m basing that off the fact that tops directly under a light show the same symptoms (as severe) as tops off in the corner of the tent. I would expect tops directly under a light (say 850 PPFD) to show worse symptoms than tops in...

    Sulfur?

    not blurples. They white with scattered red. I’m trying to reduce stretch with intense light. And also learned that when soil EC is high, plants like more light. More light needs more nutes, and the reversal as well - more nutes needs more light ( or so I’ve been told)...

    Sulfur?

    at full power it is only 400 watts with all three lights.

    Sulfur?

    I’ve got 2 Viparspectras (P-1500 and X-1500 or something) and a 100 watt Phlizon or something. The viparspectra are only at 50-75% so I’m probably running 300Watts or so in a 28” x 55” with the lights about 14” above canopy. I adjust to keep PAR under 1000 (more accurately I keep lux under...

    Sulfur?

    And still want to know what deficiency it looks like, if it does. If my soil sucks, I’ll foliar every other day.

    Sulfur?

    I know it will be. And no need to check runoff, that’s what a saturated paste test tells you. 2100 ppm soluble salts. It shows exactly what is in the soil water solution. People can be successful with soluble salts near 3000 ppm in organic soil. It depends on what it is. Na is bad. Cannabis...
