Yes ec is mS/cm and the ppm conversion is using a .5 scale. MicroSiemens per cm is μS/cm Happy Growing

FloraCoco Grow instead of FloraGro in Hydroponics DWC
Is it OK to grow in DWC Hydroponics using FloraCoco Grow (4-0-5 with also 0,8% of Magnesium) as one of the nutrients, combined with FloraBloom and FloraMicro? I'm asking because the store near home had finished FloraGro (3-1-7) and sold me FloraCoco Grow.

Nitrogen claw in hot soil. To flush or not to flush - that is the question!
Think my plant's suffering from nitrogen toxicity because some of the leaves are clawing and have yellow tips. Must be the hot soil because I haven't fed her with any nutrients. Should I leave a few days and see what happens or is it worth flushing the soil?

Potassium soil with neem oil and kelp extract as a foliar spray on seedlings
I have doubts about applying some foliar sprays. I've used Neem Oil + Potassium Soap with some kelp liquid extract, together without any issues. The benefit of using it now is obvious, but, are my seedlings too small to handle foliar sprays? Could I harm them if I apply this mix?

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)

The problem in plants when I supplying CO2
Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?

Runoff pH still climbing!
My runoff PH keeps climbing despite lowering water pH. Plants look great but have red stems. Is it possible that the bottom of my fabric pots are saturated with excess Calcium and Diatomaceous Earth? Thus, raising my runoff PH. Soil meter reads 6.8 though 🤔

How do I get the ppm level down in my water feeding?
What way can I get the ppm down in the nutrient water i’m feeding my plant? It’s high as soon as I add the smallest bit of nutrient. I feed spring still water with GHE trio. I’m in week 5 and i’m above 1000ppm no matter what I do.

When do you stop giving nutrients?
Pictures taken 3 weeks into flowering. Its 3.5 weeks now. Started as pretty basic potting soil, most of the nutrients im sure are gone. When do you switch to just pH corrected water to feed? Thinking 1 more week for my yellowing plants, and less for my very green one. Thoughts?
