I'll look into my TDS meter, and I was surprised, too about the pH and ppm (in the last state i was in where i was growing, i had the typical tap water with high ppm and decent ph)
This is very helpful. I was most wondering if itd be worth the effort to adjust ph beforehand or if id be wasting...
Thewizz, last post and ill stop jacking your thread!
Rky, I'm not a fan of rockwool in dwc already, would the transplant shock be worth it to move my normal seedling to hydroton?
The one on the right is the one that went through what sounds like the same issue as yours. The one on the left is a seed i planted in rockwool 3 weeks after i planted the one on the right, and it's already bigger.
It just seems like the one with the rockwool issue is developing its leaves...
It is dumb ha but i did the same thing for a few days before getting another timer for the pump.
Ill post pics if it matters to you later today, but i have one seedling that is going through what youre talking about and one thats doing fine in rockwool, just 3 weeks later. The only thing i...
Thanks, guys, appreciate all the tips.
I'm not worried about the actual process of adjusting the pH (I'm just using liquid pH up and pH down), just the fact that my starting pH is high.
Why I'm concerned is that I know that there can be some nutes that fall out of solution if the pH is too...
How is your rockwool? Has it gotten "mushy" or not kept its cube shape?
I started a topfed DWC last month (first hydro attempt, so just sharing my experience!), too. I had rockwool that turned soggy and would fall apart when touching it. I had seedlings in these rockwool cubes stall after...
In other words, if I leave my nute mix in water with a pH of 7.5-9 (since the pH starts at 9 and is lowered to 7.5), will this cause any precipitation?
This makes sense. I've only just started feeding and am at 1/4 strength; generally, mixing 1/4 nutes to my tap water with pH 9 leads to a pH of 7.5 after 24 hours. Then, I'd adjust pH.
My concern is that the nutes might precipitate out since the starting pH is so high. Not looking to adjust...
Hi all,
If I have tap water with a high pH (~9), will it be an issue to mix nutrients without lowering the pH a little bit first? In general, does nute lockout occur quickly, or will adjusting pH after mixing prevent it?
From what I've gathered, most people recommend adjusting pH after adding...
