I did major defoliation and trimming this week. A kilo or something,
worth of leaves. Also cleaned those zip tie filters, which caused
some tearing of the roots. After that, BSS got weird yellow and
spotty. I thought it was nutrient deficiencies, still don't know
why they are like they are. All others are just fine.
Those roots penetrate those tiny holes of those filters, they're
trying to get in to the reservoir. Water flow was decreased so
I decided to pull them out, remove all roots (a lot) have gotten
through the pipes, and wash them with hot water. Hopefully
they get it together soon. Also cleaned water pump and its
filters. Probably should change pool waters too at some point.
Also, the fixture is running full power now! No burnt leaves or
such. I red from somewhere that some people had problems
on higher power with Zeus 2.9. Maybe they grew in soil... 😅
I put that old pc fan there as an improvised cooler, I don't have
proper fans yet, because old pair of Secret Jardins died. It gets
quite hot when air is now moving that much in the tent, and I
really don't wanna destroy it.
In my opinion, all powerful led fixtures
must have some kind of active cooler, to push heat
away from the heat sinks. Unless you're growing in a big,
big warehouse or room with plenty of space above and sides.
Don't trust passive cooling!

Does anyone know what's wrong with that bottom left plant? Those spots appeared pretty soon after I cleaned those filters. I'm thinking that it's a stress caused by that cleanse, no chemicals or such were used, but some roots were torn in the process. Deficiency? Disease?
@Wanda, I think I'll keep them on veg, until they reach 90 cm / 35 inch. It's a relatively short time that goes in it, and it can significantly increase the yields. Bigger structure can also carry more bud. I bought that tent specifically for ridiculous grows. 😆
@Half_Synthetic_Growing, that's a pretty tall tent. You could let them go longer. They'll be easier to manage when they're shorter though. You'll still have the same amount of bud sites either way.
05.09 they are still good, later all starts ...
at beginning, looked like you lost it there ( maybe mismatch with nutes and spike of N, but no burn or long excess of it, so confused ) , there was spike of small magnesium issue and later they just pale back, like having ph and calcium absorption issues. Sometimes looks hungry even , but without ec values you can only guess....
Never grew in hydro, but thats how they look if would grow in soil.
@Half_Synthetic_Growing, looking at other peoples pain and only few make it - think hydro is for tough guys only ;))))
Then its a light feeder one, genetics ...
Hope you sort all !!!
@AsNoriu, Light also changed, somewhere in there, from metal halide to a LED. I flushed them today and put new stuff in, we'll see how they will do. pH is also good, around the sweet spot. They're now in lighter nutrient amount, and I pumped more water into the top reservoir, just checking if that could help the plant. Also, there's only one plant which isn't doing good, which is strange. Others are just fine and thriving. I have put EC values to every post, and based on my past experiences, pushing the plant doesn't hurt it, once it is big enough. Also I think that hydro is more forgiving than soil. You can dilute things down by just adding more water, and the plant can't drown.
Wow….long veg! I look forward to following along.
I’m still trying to learn and understand hydro (I’m a soil grower)
I totally agree with you that you can’t trust passive cooling on LEDs….I dedicate one 6” fan to each heat sink on my lights (3).
Best of luck!
@@T_Dub, I learned from a guy who did hydro, I'm just a successor for him, since he retired from this hobby a few years ago. I've never grown things in a soil. 😅 I was thinking about putting them on a flower already, did for a half a day, but then I decided to wait until they hit 90+ cm, or when that sickly plant recovers. Changed water and put lighter solution in it, we'll see what happens. Gotta admit that I'm kinda pushing this right now, even though I got a big tent.
