I run my fingers along my airlines to see if they feel slimey. Your temps are on point. Roots look good. I have that same blue tube and it's a source of algae in mine. I don't use my chiller but I use hydroguard as a preventative. My temps have gotten into the low 70s and I've seen algae in my indicator tube but the hg seems to keep everything under control.
Which ice probe do you use?
I mean my airlines are slightly slimy but nothing thick or nasty. Just a slick feeling you know ?
I’m not sure on the model number but if you just type in ice probe chiller on google, it’s one like those. It’s made for aquariums but works great on keeping my bucket cool.
Yes I do. Lol. A dealt with a lil slime. If your plant and your root zone are robust then i think the plant can handle a lil.
Well, in my case, I tried the top off with nutes, and my plant didn't like it. I went to just fresh water top off. You can try it and see how your plant responds, but remember as your plant is taking up and using the nutes, the ph buffers are also getting lower in concentration. In a small res it makes a noticeable difference pretty quick.
Okay. I mixed up another gallon of nutes slightly stronger that I’ll use to top off. I did 1 TSP Micro, 2 1/4 TSP Bloom and 1/4 TSP Cali-magic. I’ll top off my res with this and see what happens.
it seems like you are running the Lucas formula? have you tried not using the cal/mg? or are you using it because you had a Ca or Mg deficiency? the extra N is probably causing your dark green leaves. unless it is dark green from your strain.
Yeah, sorta. I’ve been using a little more of the bloom though because I’ve been thinking it was a K deficiency. I haven’t been using the cal-mag at all throughout the grow. I just decided to try a little bit this res change to see if it helps stabilize it at all and figured it couldn’t hurt. No noticeable cal/mag deficiency’s though. I’m starting to think that based on how much the EC drops and the ph is rises directly after a res change, maybe I’m just underfeeding the plant overall which is causing a K deficiency ? I mean if I’m setting the Ec at 1.6 and it drops to 1.2-1.3 in a day, she has to be hungry right? What I am noticing is that after the Ec drops and the PH rises to 6.4 or so after a a day or so, the Ec will start to stabilize and the ph will start dropping and it just basically starts going the opposite direction. The ph drops faster and the Ec starts rising. Is it possible that the EC gets so low that the plant will start leaching nutrients back into the water? I know I have read somewhere about this before but I’m not sure if it’s even possible or not. The yellowing before the burning on the edges along with the dark green has me thinking maybe it is a K issue?
Big sad
Just do a res change every other day. In that small of a container it's really not that difficult. It should stay stable for a couple days with the Lucas formula. At least in my experience.
I agree. Always start with the roots. The one picture the OP posted looked pretty good to me. Not saying it's definitive. Could be some rot hiding in there. I'd try hydroguard, if it was me, just in case.
Hydroguard doesn't work for everybody but it did work for me.
Yeah, I think it might be worth a shot. I need to grab some more boom nutes and I wanted to try some Florakleen as well at the end so I’ll pick up some hydro guard with it.
