Rusty leaves

Same here. I find I run mine a couple times a week, and I have plenty. I keep a 5 gallon water jug filled with the distilled water.

Also helps, as I have glycol chiller, liquid cooled computer, and a ton of house plants - All utilize distilled water. So get lots of benefit from it.

Mine is in garage, but noise is no louder then Grobo. Just clean it with some vinegar, and its relatively hassle free.

You should not be switching water like that.

Plants need to be in a relatively stable environment, so whatever you do, stick with it.

Great advice @vegetato! Here is the skinny @liddellOnus…

  1. A new Grobo won’t have the nute lines primed yet, an extra drain/fill will help get the reservoir filled with the correct food.
  2. Without much food in the tank, it’s really hard to maintain a constant pH level. (Think echo of an empty room)
  3. Cal/Mag is best absorbed at a pH of 6.1-6.3, so even though your reservoir has it, the plant may not be able to eat it up if the pH is unstable/low/off.

TLDR; Drain & Fill to get your reservoir filled with food and able to balance pH better.

As I mentioned in the support email, your leaves won’t heal and can be removed when they are over 50% spotted.

Cheers,
Stephen

Not for another 2 weeks. Alot of leaves die off and fall off on their own too. Just pull em out then.

The one in the foreground here you can cut near the base about 1/2 and inch or so back.

#49

maybe in a day or two you cut the back one

#50

plant otherwise is OK and will recover. Double check your nute cords and the base of them and where they are pointed

#51

Really? They look equally as bad. Just a reminder that this is an auto flower… is that going to stress her out?

And I’m on the last two days of early vegitation and the she goes into 14 day transition

#53

My auto, I ended up having to extend grow by over a month. And she was healthy, no issues like your seeing.

Usually recipe time not perfect and requires extension.

After early vegetation is late vegetation and then transition. 14 days each. Add to the late vegetation only stage

Are you adding anything to the res? On top of the Grobo nutes?

#60

You’ll end up adding time in flowring stage then, likely a month or more
