Yes, like you've mentioned earlier in your thread, once the roots hit the reservoir, growth is fast.
So, at the end of a run do you dump the soil out of your SIPs and just re-amend and re-use it? If so, do you just add some Epsoma garden tone and maybe a bit more perlite, or how do you re-amend?
I run a coots mix, but I've just been dumping it into outside garden beds when a run is finished, and mixing a new batch every run. Eventually, I want to re-use my soil just for the $ factor. What is your soil mix?
I'm finding some strains, and/or phenotypes are ok with how I feed them and they stay green (except of course some lower fan leaves) for the most part, and form nice buds, and finish well. However, I've had a few that though given the same conditions and feed, struggle and either need more feed, or maybe they get locked out, I'm not sure. Right now I have an Orange Cherries (Dynasty freebie) in one SIP in my 4x4, and a GMO zkittlez from Ethos in a second SIP. The OC is doing fine, green leaves, forming nice buds ( bit of foxtailing, so I've been raising my light) but generally look good, whereas the GMO zkittlez was a bit mag deficient early, ( so i foliar fed epsom salts a few times in veg) and even though I was feeding basically the same otherwise as the OC, now 7 weeks into flower the GMO zkittlez looks horrible, hardly any leaves left (buds surprisingly look ok) and I just hope to limp her across the finish line. I think she maybe needed more nitrogen early flower. I am thinking I may try to run the GMO zkittlez again and wait to switch to bloom nutes a bit longer ( I use Gaia Green 4-4-4 and 2-8-4) .
Gaia Green doesn't have any microbes in it. Would like to try that Epsoma Garden Tone, or maybe Dr. Earth general purpose as they both contain microbes in their formulations. They are very expensive to buy in Canada, so not sure that's really an option. Maybe I can just buy some mycorrizae and use it as a soil mix ingredient to get some microbial life going that way.
Sorry for the bookish post in your journal. Maybe I should have posted in "plant problems" thread, but I'm curious about your methods and love the results you have been getting.
