answered grow question 6y ago
No. You need to drop it to between 6.0-6.5 for soil. Or 5.5-6.0 for Coco or hydro. A pH down solution will be required or you will have lockout issues. Happy Growing! 🤟😜

Tap water is 0.5 EC, and 8.1 - shall I get an RO system or can I use pH Down (using Canna Coco)?
Does my tap water with 0.5 EC, pH 8.1 warrant the use of an RO system with Canna Coco nutrients or shall I use Canna pH Down to bring it down to 6.3?

tank feed
How long can I keep a mix in this tank. I must admit it does not smell good. The mixture smells so bad after a day or two and does it affect the plants in any way?

Plant does not drink nutes500ppm runoff
Why the smallest plant does not drink nutes ? The one in the video that I mention is having 500 ppm run off . What shall I do with the nutrition in order for the growth to explode like the other plants? What else I can add in this case and do I need more light for this amount?

I have a problem with fertilizers!! why are some particles floating in the water on a new three-day solution similar to those that have settled on the walls of the pot! that is why some kind of sediment and brown flakes and small particles that float appear on the new solution!

Anyone think I should add Nutes or just let her do her thing? If I do, it would be fox farm Big Bloom or Tiger Bloom?

Watering in Super CoCo
Hey there fellow growers! So I’ve been trying to figure out the best watering schedule and volume 🧐I’ve been told to always water with runoff, go by weight, top inch dry, etc. I guess my main question is runoff necessary when watering in Super CoCo? All advice appreciated!🌱

Demineralized water to finish
Hey folks! Got a question about giving fresh water to finish. I bought some demineralized water to give them for the last week. The problem being I can't seem to get a reading on ph. I'm assuming because there's no ions in the water . Is this stuff ok to use opposed to distilled?

I grow one plant in a five-gallon grow bag filled with coco coir. I water her everyday and on every third day I feed her with my nutrient solution. Everything so far has been good - growth, color. The pH and PPM of solution is 6.5/ @1500. What do you do when growing in coco?

Compensating for Effect of Supplements on PPM
I decided that my girls probably had a calcium deficiency from using distilled water. I added a cal/mag supplement and an enzyme supplement. Now my PPM is through the roof. Should I reduce nutrient levels so that I'm still in the desired PPM range?
