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! 🤟😜

EC and PPM
I read about EC and PPM. I have a meter that reads both, and it says my PPM is too low, and the number it gives for EC is like 1200 and the charts all have numbers like 1.2-2. WTF. I ran out of pH strips but I know my pH is good, I used distilled water. What's everyone's thought?

EC madness!!!!
About EC. Er...confusing eh? So, if I feed with 1200 and it comes out 2000, I need to lower the feed until it comes out 1600? And if I feed at 1200 and it comes out at 1400 I can increase? Right? Is the whole point of this to give the plant as much feed as she can take?

When to introduce nutrients to coco / perlite and how to water seedling?
Hi!! I am doing my first ever grow. When should I introduce nutrients to my plants in coco? They have just sprouted and I was only giving them some water with H2O2 at a PH of 6.2. For a seedling, do I need to water until I get runoff? Thank you!

What is the best (cheap) TDS meter? (Also i think they should allow longer questions because 280 characters definitely not enough to describe everything).
On the internet and i found A LOT of TDS meters with prices that vary from 10€ to 200€. I decided to ask you: what do you think is the best cheap TDS meter? What do you use? What's the key thing I should considerate when buying one? Are all the same and i'm askin stupid question?

What bottled water would you recommend with a good ph?
I am currently using my tap water left out for minimum 48 hours before use but have noticed leaf drooping, PH of my tap water is 7.28 is this too high? I was previously using melted snow and had no issues, but have not had snow/rainfall in weeks so ran out.

Soil getting less
As everybody knows, when we watering soil, it gets more less in every watering. If I add soil when it gets less, will it be a problem ? Because I'm using Plagron Light Mix, it has fertilizer.

When to start flushing
Should I stop adding nutrients and just give the plants plain water now? I'm in Week 8 and many of the FastBuds Pineapple Express Auto grows I've seen harvest around week 10. Would switching to just water be a sufficient flush?

DWC water change or NOT?
DWC - The DWC smells good, there are no signs of rot or foul smells - I use 3% H202. I keep the temps under 22. The plants are doing great. Should I just add in my flowering nutrients and let it keep running, or should I disinfect and do a full change? Thanks in advance!
