Flower N-P-K
displacedtexanstarted grow question 4 years ago
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.

Hey Growmie,
A general rule of thumb is to remain close to a 3-1-3 (N-P-K) ratio for the first few weeks. During flowering, it is best to reduce the proportion of nitrogen to phosphorus and potassium compared to the ratio used during the vegetative stage. It is essential to lower the portion of N at this point. Hopefully, I answered your question and remember ..."Happy Growing" and "Free your mind one puff at a time"

General rule of thumb: vegetation: High N, Low P, High K.
Flower: Low N, High P, High K

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

Do you suggest a hard switch like in the Canna schedule, or do you prefer transitioning by mixing the fertilizers?

Canna Coco ARecommended mix ratio for Canna Coco A & B is 1:1 throughout a grow. Combined NPK is 5:4:3 (A: 4-0-1 & B: 0-4-2). Is it beneficial to change the mix ratio in flowering stage to lower the nitrogen component? (for example; 1 part A & 2 parts B)Feeding. Chemical composition
