Am I right waiting longer until feeding for the first time? I heard overfeeding your soil can be very harmful to the roots.

Now is about the time you'll want to add some base nutes. Always start with the lowest dose or 1/2 strength 👍🌱

Runnoff measuring results are not what I expected.
Hello, I have a question. When you look at my diary, I find my runnoff measurments to be concerning. Why do you think my PPM is so high and my pH so low? How do I measure my runnoff correctly? Do I filter it before reading or do I let it wait?

Hello community! I broke 2 branches this week. The first one happened by accident when I was draining the runoff, and the other when I was bending it.
And today I came across a video where the author explains that silica can cause brittleness of branches. Does anyone have experience with silica and have you experienced anything like this? I add potassium silicate with each watering, at a concentration of 15ppm

Very abnormal EC Runoff for CoCo Coir - please help on what I should do. I am scared to increase nutes in case I get nute burn
My EC going in is just under 2,000 (The maximum it should be much later in flower according to online) but comes out much lower and is getting lower each (735,467,368 respectively). Online says that Coco runoff will always be higher t- what should I do? I am scared to increase

Nutirents for hard water
Question regarding the correct fertilizer amount. Advanced Nutrients. If my water already has a high EC of 0.75 I use less base fertilizer (Bloom A+B). But do I also reduce the amount of additives like Voodoo Juice and Sensizym, etc? Is there anyone here with experience with AN?

When and how do you switch from Canna Vega to Canna Flores? Feel free to share any tips. What are your "signals"? Do you suggest a hard switch like in the Canna schedule, or do you prefer transitioning by mixing the fertilizers? If you need more info, please check the diary.

pH irrigation / runoff
Why is the pH of the runoff so much higher than the pH of the irrigation water? Is the runoff or the irrigation water more important to consider? Canna Terra Professional Plus and BioBizz pH- The pH lowering effect seems to vanish in the fertilizer solution after one to two days

Flower N-P-K
Is there a good "rule of thumb" N-P-K to start with for flowering? I have a 4-6-3, 3-9-4, and 2-2-2 to mix for various N-P-K's. I'd like to get close to an ideal mix when I top dress in a few weeks. I know fertilizer needs will vary by strain, but I'm interested in a baseline.
