So 1ml of each per litre of water will increase your ec by nearly 1.2

I think gro 1ml/L is ec 0.4 increase. Think micro is nearer ec 0.5 for 1ml/L and bloom is about ec 0.25 for 1ml/L

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?

i don't know where the fault lies, my plant is growing too slowly and the leaves on the buds are deformed. The last time I tested the soil pH was 7.5 even though I watered at 6.5 and the runoff ppm was 1800. Can anyone tell me what I should do now to make the plants grow well.

EC value
Hi again! Found this EC table on RQS, according to this I should have an EC of around 2.2 this stage. I feel like this is a bit high. I checked other grows on this forum and I don't see many going over 2. What are your thoughts? Thanks!

Is the PH spike from adding Armor Si (or the like) short term? Meaning will the PH slowly drift downward as the bucket ages through the week as it's effects wear off?

Why does coco nutes often only have one A B blend, instead of 2 seperate Veg and Bloom blends?
I personally use Plagron nutes in coco, hence I use the same A+B bottles for veg and flower. When looking at nutes for soil they have the 2 different bottles for veg vs bloom. So my question here is why does it seem like some coco lines(plagron, canna) only have 1 over both?

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

1 week into flowering, no pistils on preflowers yet. Change to flower nutes, or what?
Hi guys a couple of questions: 1) When should I change to flowering nutes? I heard high nitrogen can hold back flower formation. 2) Should I be concerned or look out for anything else? Background: - 1 week after flipping to 12/12 - Very vigorous and healthy (in DWC with CO2)

Thoughts on compost tea?
First time making compost tea, if anyone can think of anything to build on, would appreciate some knowledge. Already have a 4-4-4 mixed in to the coco coir, so I’m making the tea out of 🍅 fertilizer for calcium and molasses for sugar.
