Tds/ec neccesary?

I personally don’t use a meter for anything anymore. I have my routine dialed in and only use it for dwc. You can try via trial and error, but that’s up to you! Maybe try it with a photo first as autos are hard to diagnose any issues as they can be from the plant versus the soil/nutrients. Good luck ✌️💚💨🌿

I've never used a TDS reader before and all my nugs turn out delicious. Most nutrient companies have feeding charts for their nutrient lines. They're pretty easy to find online. So, just get a feeding chart and knock a quarter to half of the amounts down while using the same amount of water. Bingo bango bongo, you won't wanna leave the jungle!

I think it would be terribly beneficial for you to have a ppm meter - they're quite inexpensive and you can calculate the EC yourself from the ppm reading. That equation is (ppm*1000)/2. Then it's necessary for you to know what EC range is good for your autos at what age... For Week 1 - EC between 0.2 and 0.4 Week 2 - between 0.4 and 0.6 Week 3 - between 0.6 and 0.8 Week 4 - between 0.8 and 1.0 Week 5 - between 1.0 and 1.2 Week 6 and on up to a week before harvest - maintain the EC between 1.0 and 1.2 Week before harvest - EC between 0.2 and 0.4 Hope this has helped! Vivosun makes a very nice, quite reliable ppm meter you can pick up for or so...

The small investment for a pH and EC pen and pocket microscope x60 can provide you with a lot of high quality cannabis. You can get all of them for under 100 dollars. When you grow with a living soil you do not need to measure but you first need to learn how to let your soil live in balance so it provides everything your plants need.
