If you are using quality soil, I would not feed anything for at least 30 days. Then 50% solution every third watering. Just my opinion!

Normally I just give ph water in the first week, and the second week I start giving nutrients half dose of the brand chart and I increase gradually the dose.

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?

a friend wants to start with his first plant. Unfortunately, he doesn't have much budget. And through the Corona eruption, he has to work with what he has. As soon as he has the money, he absolutely wants to switch to the right additives. Is it possible to use one of these.

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.

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?
