I think you wont get enough nitrogen and you will have too much potassium.

I would also include the gro.... the second video with the air looks better remember you just need enough to agitate the surface.... not beat up the roots.

You. Need. Nitrogen.

Interesting.
How much nitrogen do you think I need?
To be clear, you all recommend adding the Flora Grow so that I can get more nitrogen??

Can't speak for others but that's my opinion. 100-120ppm of nitrogen is about where I like mine generally speaking.

The Flora Grow has less nitrogen than the Micro...
Am I missing something here ?
I will break this all down if need be. But I thought this was a well known formula.It’s been years shit changes though. And that’s why I switched from Lucus over the years.not only to try out different companies with specific formulations, but just to see how the cookie crumbles on the other side. And honestly, when they are healthy in DWC, nutrient changes as negligible imo.
To clarify, We do know this is 0/8/16
Which is 0 grow, 8ml micro, 16ml bloom /gallon
Just want to make sure this is understood by everyone
I also don’t run it at exactly 8/16
more at 1:2
I bring up my PPMs slowly as plants uptake.
If I see signs of nitrogen deficiencies, I will up the PPMs.
Lucus himself recommends going full strength nearly the whole time.
I could never get myself to run clones at 1300ppm from start to finish

Yeah i have heard of it and seen some tables... always nitrogen in it. I was looking at the ratios you posted as NPK and thats not the case. What is the NPK of the mix you describe. Honestly never really looked into the Lucas formula much

I honestly used it for simplicity when switching from soil to hydro years ago. Time flies, and I’d be dammed if they haven’t perfected a simple cannabis nutrient regimen by now. I understand there is a lot of great options. However the Lucus formula can be used with any nutrient line, and is more focused on the ratios and numbers more so the name of the brand.
Here is the info on the Lucus formula using GH Flora Micro andBloom
“Lucas Formula targets (parts per million) of 100N-100P-200K-60Mg as the requirements for marijuana through all stages of growth. Using 7.5 ml/gal of FloraMicro, and 15 ml/gal FloraBloom, 122N-99P-171K-68Mg is achieved. Lucas Formula rounds off to use 8 ml FloraMicro and 16 ml FloraBloom, so the N-P-K-Mg ppm will be slightly higher than the previously stated 122N-99P-171K-68Mg values using 7.5ml/15ml respectively. Using 8 ml FloraMicro and 16 ml FloraBloom, the N-P-K-Mg values are 130N-106P-183K-73Mg. The total PPM of the solution will vary depending on water quality used. Keep in mind that there are also other elements in the Micro and Bloom bottles besides the N-P-K-Mg, so the ppm will be higher than if you simply added together the previously stated N-P-K-Mg ppm.”
My trouble is the amount needed. I don’t feel comfortable using 1300ppms on clones. And I never have. I think I still need a better understanding of that aspect, regarding how much of any specific nutrients the plants need at any given time.

Looks decent.... its the ratios that are important. From there just dilute to meet your needs.

What nutrient line do you recommend in DWC to be ran with Hydroguard?
Any remarks on
Aqua Flakes
Canna
Dyna-gro
What do you do differently AquaMan compared to your first run with the 4x4 with MegaCrop?

I have a lot of dry fert amendments from when I used to mix my own. I'm tinkering more now with ratios at different stages. But I feel like there is no real best nutrients but the overall rarios we use are the important factor. Things will vary strain to strain and thats where it starts to get to specific and i dont have a lot of the answers. Probably the best thing i can say is I found a 2-1-3 ratio with Ca to mag of 2 or 3 to 1 to work well from start to finish. Normally adding mpk after flip which I have changed to before flip but I won't get into the parts im tinkering with. Generally speaking that works well start to finish. Other than that more specific ratios and amendments I feel should be reserved for strain and pheno specific grows. It boils down to reading the plants, trial and error and just having the individual nutrients on hand to do so.
Pretty much the lucas formula and many others are proven to work a to z getting more out of it is strain and grow specific and needs to be treated as such. Let's the plants tell you what they want. I know it's vague but there is no right answer.

So the Skywalker OG clones have been in for 24 hours now. So far, so good.
These clones were not nearly as rooted as I would have hoped to of received.
There was also an extra clone in the bag, so I decided to run that one in a 5 gallon bucket, I will then choose the 2 best ASAP.
I’ve been ensuring the rockwool isn’t getting too wet or dry.
I placed the rockwool on about 2” of hydroton in the netpot, and then filled in the rest.
The bubble bucket hasn’t needed any top feeding, but I’ve found both the ladies in the 150L Res rockwool were drying out slightly.
Light Intensity 25% of 720W
Water temp 64-65F in both the Cooler and Bucket.
Bucket PPM 160
Cooler PPM 150
I did have an incident today when I woke up in the morning.
My AC ducted exhaust had fallen off the AC unit. The room the tent is in heated up to 105f with the current outside temperatures.
The tent itself was up to 90f at the highest.
The plants looked surprisingly good, actually better then when I received them.
I decided to use the 2 clones which had the best root system going so far. As you can see from the pictures, one of the clones I placed in the larger Res by far has the worst development going on up top. But we will play it by ear, and soon enough only the strongest 2 will remain in the tent.
The other will be trained, poked, and prodded
Tent temperatures are back down to 74-78f
I’ve managed to get the humidity up to around 40-60% pretty steady with another humidifier added.
I’m also contemplating on running Aqua Flakes A&B in the larger Res, and the modified Lucus in the bucket. Or vice versa.
Anyone have any input on the AquaFlakes?

As you can clearly see, not only did 2 of the clones essentially have no roots popping yet, but they also came having undergone some less than ideal conditions.
Dark, crusty tips. New growth looks deformed.
I’d normally prefer them to be in better shape. But it could be worse.

I like using the garden fencing that's painted green and has 2x3-in squares. You can lay out four branches north south east and west, top them at three and then three again and it will fill out perfectly. It's also much more sturdy than netting so when you're bending a branch it holds itself rather than having to tie a bunch of stuff down. Not that the nettings bad or wrong I just did it different and got great results.

Regarding your point that the clones weren't rooted as well as you'd like... We had some lids that were slightly tinted and as they got more and more tinted we got worse and worse results. We replaced the lids and were right back to where we used to be. Once those lids get dirty it's just best to throw them away and get another one. It's like when you see a Honda or Toyota with a cloudy headlights. You can polish that out but it's not worth it on it hood. Has anybody else seen this?
