It could be that they never got going, much like trying to start a compost pile with too much brown material compared to the greens. The balance is important and with the amount of rice hulls you added that could have thrown the mix off.
What my Dad calls a “High Quality Problem”!
Ahh, ok!! Muchísimas gracias, doña @Emilya Green !
Well, that depends on if you precharged it or not. If you didn't, it will act like a sponge, absorbing nutrients and sequestering them for later. If you did precharge it then it just sits there like a full battery and will only start giving up its goodies when they run low in the surrounding soil.
Keep in mind we are talking about a microscopic environment and what looks like a moist environment to us is a flood to the tiny microbes. They swim around in that moist environment breaking stuff down and consuming each other. And, with no wet/dry cycle, they stay active throughout the grow without many pauses along the way from the traditional dry periods.Only, what does it moderate in soil? The soil touching it?
And how does it moderate it in soil? (In liquid, I could understand it. But in soil???) Because in a SIP, isn't the soil mostly moist? But there are no periodic "floods" of liquid...
Sounds good, Azi!
Sigh..... So I messed up out of lack of knowledge again!!
Ahh, ok.
Ahh, ok. That makes more sense now.
Siiii......
Working on that now. It didn't work for me when I had hydroton clay balls at the reservoir level which held up the soil keeping it out of the reservoir. I am hoping that with my organic soil now down at the reservoir level that the microbes would also be present and maybe they were the missing link.
I don't think of them as necessarily smart but more opportunistic. Roots grow out in all directions and then gravitate to wetter areas. The roots in the drier areas are weaker and smaller and the roots that found the wet grow stronger.
There are many types of yellow tip yellowing, all indicating different things, so be careful in how you react to that general condition. Many people associate the yellow tip, the small mini triangle type, with burning. It is funny though, that most true organically fed plants exhibit this peculiar condition. It turns out that the same signal that is sent out to the microbes to shut off the supply, that thank you, we have had enough for now... That same signal is what causes the mini triangle indication at the tips of the leaves. Your tip situation looks different and is commonly associated with potassium deficiency, or as we have discussed maybe not an actual deficiency of potassium, but a lockout instead.Ahh, ok!! Muchísimas gracias, doña @Emilya Green !
I will back off on the N.
I did some research on my liquid nutes, "BioNova Veganics."
They say they are mostly derived from algae (kelp??).
Since they are liquid, if there is still tip yellowing after I back off on N, maybe I could add some of that to the res?
Thank you!!
Yes indeed.
Better take lots of pictures. And be careful opening the tent.
Including all your secrets??
Well, we'll still be here when you do.
.. I'll have everything after next weekend and then we can go again! same light, same strain, same nutes.. the difference will be the watering pot vs soil perlite grow bag.
I like to treat the seedling with minimal water, and just like you would if planted in its final container in a normal pot, at least for the first week or so. Then I put a little water in the reservoir just to set the mood. Once it starts growing well and drinking from the reservoir I gradually increase the amount down there which helps establish the moisture gradient.
Damn Will I didn't know you were SIPping outside! You got a journal I could follow?
Definitely not. The sun moves across the sky and there are no buds on your plant that aren't getting light at least some of the time.
Looking good, Will!
Maybe there is something to these SIP pots after all. 
Ah, the big defoliating question. Some growers swear by it saying it encourages the plant to repair the small stresses from it and makes for a heartier plant. Others say the leaves are like solar panels and the plant has them there for a reason so leave them all on.
Hey Hash,this is a 5g EcoGrow Pot sip. Could also be considered a hempy. There is a rim about 2" from the bottom with holes in it for the overflow. Black Gold Organic and some powered nutes.
This clone of my widow was started in water, showed roots in 11 days, 4 weeks in a 4" pot then 2 weeks in the sip.
day of transplant
two weeks later, flipped today
