Excellent knowledge being dropped, thank you man.
In regards to dry salts - I am inspired, and now I venture forth now on my first attempt.
I think I've pieced together a nutrient profile for coco using some of the starter pack ferts on CHN and calculating with SaltSmarts (great tool).
One thing I'm not sure on is Si ppms (best guess is ~20ppm). What do you think is appropriate? And do you continue using Si during late flower? I've read that it may have adverse affects in late bloom.
And on a side note - Have you ever tried not flushing?
Thank you again for your time. I have read all your posts along with much by c64 and have learned a lot. Beautiful looking flowers with no hyped voodoo juices.
This guy knows whats up, very nice setup too.
Buds are huge and frosty.
Mixing his own ferts too.
Talk about well rounded.
Nice work brother, nice work!

Thank you for your response! Salts ordered...gearing up for the next run in a week or two.
May I ask for some elaboration on your drip irrigation setup? I am converting a 4x8 flood and drain table to drip and have a couple different ideas of how to go about it.
Basically, my primary plan is replicating the setup here:

and similarly here as well:

It will be a bit of a challenge to construct this manifold given my skill level with this sort of thing, but I really like the design. My question is, do you think there is a simpler way of going about have even flow for 18 sites? I see your setup utilizes the inline valves and top hat grommets with a pvc grid. How's that working for ya? And what the heck is that cat litter bucket next to your rez for...drainage for the condensation from A/C?

Please forgive me for double posting...I am not allowed to edit my posts. I have some new issues popping up with my formulation for dry salts.
For Absolem and others with an interest, please see attached for the veg formula I have come up with (flower formula would just add or remove calnit / pk boost). The actual amounts of each salt added to achieve this are not included as that is unique to compensate for the levels of my tap water, buy you can see on the "Input" column what I am looking for and the "Output" column for what I can actually do. These were generated via saltsmarts.com. I came up with these numbers by piecing together information on the forums and comparing to recommended levels for tomatoes.
I'm running into an issue with not having enough Sulfur as I use this element for my degree of freedom in order to accurately achieve N, P, K, Mg and Ca numbers. I could increase Mg or K to up my sulfur (via potassium or mag sulfate), but it would throw those numbers out of whack.
Additionally, I am a little unsure on ideal Fe levels.
I'm wondering what your opinion is on the importance of hitting a particular level of sulfur and iron, and whether not in the case of sulfur it's worth adjust Mg or K to do so.
Thank you for your time, Absolem.
