I ran into a Cal-Mag deficiency due to an excess in Potassium. In trying to circumvent the problem with the Calcium deficiency, I tried Foliar spraying the leaves with Cal-Mag in attempt to deliver the calcium via the leaves but, had no luck whatsoever. Does anyone know the correct procedure...

Some photos of a Skywalker OG, week 7, day 3 of flower. This plant has been mostly problem free until I spotted something on just a few leaves. Don't know if fungus or insect. Any help would be appreciated. Thank you,. Here is a close-up of one of the leaves:

I am growing in soil (10 gallon pots) and a couple of days from end of week 5 flower. A few of the small leaves on top are showing light green on the edges (first observed yesterday, spotted more today). Not sure what the plant is trying to tell me. Other than that, the plant has been mostly...

I have read that top dressing Bokashi onto your soil is recommended because it increases the microbial activity in the soil. If Bokashi is used to top dress, is it necessary to add microbes to your soil or does Bokashi supply all of the microbes we need? Are there any guidelines when...

From Royal Queen Seeds: Cannabis seedlings get all their nutrients from their seed, and absorb water via their leaves as their root system develops (that’s why it’s important to keep them in a warm, humid environment). You won’t need to start feeding your seedlings until they’re about 3–4 weeks...

I am in the flowering phase now and have a couple of plants in 10 gallon pots with Happy Frog Soil. Some questions: 1. When to add nutrients. These plants are small, about 12 inches. I have Dr. Earth's Flower Girl I'll use for P&K. 2. Do you find you have to add Calcium & Magnesium ? 3...

I was wondering if I mixed some happy frog with ocean forest, what would the resulting ph be? Assume 5.8 from ocean forest and 6.8 from happy frog, is there a way to know what the resulting pH would be if mixed at a ratio of 1:1. Is the pH change immediate or does it take awhile for the soils...

Curious to know your opinions on the pH range you have found that gives good bud when growing organic?

I just made up some soil that I'm running with now that I made in 10 gallon batches. Each batch consists of 8 gallons Peat Moss, 1 gallon Compost, 1 gallon EWC, 1 cup Barley, and 1/2 cup Oyster Shell Flour, so each batch contains 20% organic matter. I was curious if anyone knows the minimum...

I know there are some folks in the Organics section have used this product. I used it for the first time a couple of weeks ago. I had two plants in the 5th week of flower that I transplanted into 15 gallon fabric pots. I used Super-thrive (1/4 tsp per gallon) on the plants a couple of days...

I'm thinking about growing in Peat Moss without adding EWC or Compost. Is anyone growing in this type of medium and if so, how is it different from growing in a soil medium?

Another surprising Soil Analysis. Peat moss + EWC shows a bunch of nutrients. Ingredients: 8 gallons peat moss, 2 gallons Earthworm Castings, 1 cup Barley, 1/2 cup Oyster Shell Flour.

This one really surprised me; this is compost that I get from my local nursery. Research on the internet indicated to me that compost is not so high in nutrients. Note the micronutrients - compost seems to have more than rock dust. My first soil report revealed excesses in primary and...

The Premier brand of Sphagnum Peat Moss is where High Sodium (NA) is coming from but I don't know if it is elevated enough to cause growing problems. Anyone use a different brand of peat that has a lower sodium content? Also, I was surprised to see that you can find so many other nutrients in...

This is the second soil report from a Coot's Mix. Ingredients: 6 gallons Peat Moss, 2 Gallons Compost, 2 Gallons EWC, 1/4 cup Karanja/Neem, 1/4 cup Kelp Meal, 1/4 Cup Crustacean Meal, 1 Cup Barley, 1/4 Cup Gypsum, 1 cup Oyster Shell Flour, 1 Cup Basalt Rock Dust, 1/4 Cup Glacier Rock Dust, &...

Informed by Buidasoil that Basalt Rock Dust is rich in micros, I added 2 cups to my soil and a Soil Report showed all micronutrients (except for Iron) were very low. According to BAS: "We've found a local Basalt that we're excited about. Basalt rock dust is packed with micronutrients like...

This is a recent soil report and I have a question or two and looking for helpful comments. I can see a micronutrient supplement without Iron will be needed. I will transplant into this soil at the start of flowering, so Nitrogen should be okay. Is there enough PK to see me thru a flowering...

For every 1 gallon of soil, I mix in 1 quart of Perlite which seems to offer good drainage. Some say you should use as much as 50% to get better results. To put this question to rest, how much Perlite or other Aeration amendment should be added to your substrate?

I use 6 gallons Peat, 2 Gallons Compost, and 2 Gallons EWC. Is this considered Soilless, Soil, or something in between? PH runs 6.7-6.8; Is this okay or should it be lower?

I've been getting nutrient burn on my seedlings and was looking for some advice on what to use to give them a good start. Also taking long time for the plants to grow. I started two plants about 6 weeks ago and they are only about 6 inches high. I think nutrient burn has partly been...
