Still trying to resolve my issue with alien moonrock




The first photo was yesterday morning. The next two this morning. System is Baby Bloomer ebb and flow and FCE4800 in 3x3 tent with remote fogger. Temp held around 75 and RH at 67-70. Prior the ph was climbing to 6.6 and ppm was 1080 using only GH Floranova. Yesterday I drained the 6 gallon reservoir and refilled with my well water. I added back GH and included FoxFarm CalMag. Numbers now were ph 6.1 and 900. This morning ph was 6.6 and ppm around 950. I partially drained the reservoir and refilled. Ph is 6.1 and ppm is 660. I cycled the water and now ph is 6.6 while ppm held at 660. Okay, I drained and washed everything. I also flushed the media. Refilled with no additives and am running a fill cycle. Ph is 6.1 and ppm is 30. I’ll drain again after the cycle and refill with more fresh water, watch the numbers all day and add flora, fish shit and calmag in small amounts. The fogger hose was dripping into the media so maybe that was causing the ph climb?

I’m not a hydro grower, but you got algea on your clay pebbles. All the hydro grows I’ve seen have everything under the base of the plant totally hidden from light. Algea csn wreak havoc ov your root system and gum up all of your lines, buuuut can’t grow in total darkness.

Makes sense. I’ll come up with something to block the light.

Like @Borderryan22 I’m not a hydro guy either but the PH should be 5.8

That seems low?

EDIT: Discard the ppm comment.

I’ll need a real ph lower solution. The white vinegar is tricky. I’ve read ph should run from 5.5-6.3 in hydro. Everything was great until three days ago. Hopefully, the full flush and adjustments will work.

5.8 being the sweet spot

This is correct. I’d be willing to bet most of your issues are related to unstable ph.

Right now I’m at 6.0 and 670. Hope to buy some ph adjuster today or tomorrow.

In what order are you mixing nutrients? :thinking:
Cal mag should be added first unless you are adding Silica then it would be Silica ,Cal Mag followed by Micro Grow Bloom.

@Ebb ??

One sec i have some running to do and ill be back.

I’m using well water. I haven’t used silica but added the nutrients then calmag then fish shit. It was done in minutes not hours.

You should always add cal mag to water first then add micro grow bloom ,in that order.
then adjust pH.

Yep :point_up_2: this is most likely the issue

“You should always add cal mag to water first”
I’ve never done them in a particular order. I add them all and give the 8 gallons a gentle stir, then wait a bit and check PH.
So why Cal/Mag first?

Hydro is a very specific style of growing you can’t just throw things together and expect it to work you need to research your growing style probably should have started with soil and learned how to grow and then went to hydro :v:

Most will say this just because it’s what most of the fertilizer manufacturers recommend. The reason is because calcium precipitates easily. So as a general rule it’s recommended to get this dissolved and into suspension first. But this is far from the only way to do it.

There’s just as many people that will tell you silicate first for the same reason.

You just need more pebbles to cover the water. When the table is flooded you should only see the pebbles, no solution @Wizbang . I have a tiny amount of algae but I use Z7 and Hydroguard and I just changed the res after 10 days and it was clean. No green.

@Wizbang , Cut a piece of black landscaping plastic to cover.
