Nute & Reverse Osmosis questions For Hydro

[Incredible4Mr2E]

Can you guys tell me what’s going on please?

 

[Thundercat]

I have this grow at least to figure out what to use for next time. Thank you for all the advice. I talked to someone earlier in this thread about all this stuff. I found so much conflicting threads on it. One thing that stuck was someone said the weed burned differently when using pool shock and stuff. Some think it won’t work at all lol.

Pool shock does not change how your plants burn or smoke. I used it for almost 10 years running flood and drain hydro to keep my res nice and clean after an issue with bacterial blooms one summer. You use a tiny amount of it and chlorine evaporates quickly so it’s not going to build up in your system. Chlorine is actually a tertiary plant growth nutrient. Anyone that doesn’t think pool shock will “work at all” doesn’t know shit honestly.

Chlorine is widely used in commercial grow ops for food and cannabis

Do you have to worry about your water temps with your system?

It’s best to keep it below 70 but I’ve read it guys running near 80 with chlorine and not having issue but I personally have not tried those temps. If you can chill it to about 68-70 and run sterile with no organics you should be fine. With all those bottles I would try to stick just to the base nutrients. Micro,grow,bloom as they shouldn’t have any organics and all those stimulants your trying to introduce aren’t needed to grow great stuff

I keep seeing these YouTube videos and things saying crops went up xx% since changing to AN. I figured what the hell, but now I’m not thinking that at all.

I was originally thinking about going with jacks. I decided not to bc the AN is ph balanced. I work for a Union, so I’m always a couple hrs from home and only get three, four hours a night at home. I was just hoping to get this system in check and be able to leave it for 14 hrs a day without babysitting it. I’m going to scrog it out, so I know that’s going to take some patients and time. I’ve never done scrog, so I’m excited to see how it turns out. The schedule I have from AN says to add all them bennies. Guess I’m going to run this, see how it does. I calculated wrong on some of the nuts I needed and didn’t get enough for the system for the whole grow. 300 bucks didn’t get me enough for one grow on two plants. I’ll have to do a lot more research on dry nutes and invest in a dosing machine for ph. View attachment 5010294View attachment 5010295

That is a lot of nutes. How big of a resevoir is that supposed to be for?

The system is 20 gallons between the 2 plant totes and the control bucket. I thought it would be more but filling it with measuring it only 20 went in and filled to the bottom of the net pots.

 

[70's natureboy]

That puts you around 15 ml/gal for the base nutes. I don't know how watered down that stuff is but it's about twice as much as I use with GH. You should invest in a Truncheon stick to keep track of your nute strength. If you like to buy the best of the best then the Truncheon is what you want.

 

[Incredible4Mr2E]

So, any idea what this is? Started from the top working it’s way down now. Can’t figure out the color but figured out what light burn is. They went into flower the 10th this month

what do you see? take a closeup of what you are talking about.

and some details too: EC, pH, etc

I was burning the plants, I could tell bc they were tacoing really bad. Heat doesn’t go above 81, the fans weren’t blowing on them very hard. Humidity is always around 50% +\- 5%. PH stays around 5.8 +\- 1. TDS says 680, but I’ve been feeding the AN to almost full strength and should be higher I feel. I turned the light to 320 and all the way up. It stopped the burning for the most part. Last Saturday I put Hydrogen peroxide in it by mistake being dumb and stoned. I have it 24 hrs to burb it out. That’s the only thing I can think of but I have no idea. I feel like the light is burning them now.

light distance to top of canopy is? light burn is more of leaves turning white. i don't see that.

is your EC dropping/rising/same?

The lights a little over 3 foot away now. I just don’t think it’s the light but at the same time the plants both responded to it being turned down to 320 watts and all the way to the top of the tent. Then, like a moron, I thought putting peroxide in would help not thinking about the live bacteria. I mixed up 24 gallons of RO water, put the peroxide in and let it sit for 24 hrs before adding my nutes. I just feel something off. I just checked PH and it’s at 5.5 now. The PPM’s only go down about 100 by the end of the week. I top off 2 gallons everyday with fresh Nutes added in it. I haven’t had any issues until I did my water change Sunday. 2 days later and it’s getting bad. Do you think the Peroxide threw my ph off? I just added two drops of PH up, I’ll wait two hrs and recheck it. Here’s some pictures I just took. The ends are starting to curl down now. Jesus I’m a dumb fuck for adding that peroxide. I knew I should’ve dumped the water and redid it. Bottom leafs are definitely not turning as fast tho

 

[rkymtnman]

looks like they need some Mg in some of those fan leaves. maybe let your pH go up to 6.1 for a bit. Mg is better used above 5.8

and the roots look good still?

Do you think it has enough Magnesium in the nutes, my PH has just dropped and isn’t taking enough in? I can recall reading responses from people who use 100% RO water and saying they almost have to add Cal/Mag or calmagic or something. You think it’s best to raise the PH first, check the plants after to see if they come back before adding anything? I really think the peroxide threw my PH off. I don’t get why the ends of the leafs are starting to curl down, suggestions? Is that from low Magnesium too? Honestly, should I just flush the system with new water? When people do flushes, do they change the water with clean, no nutes water, run it for a while, flush it, and after, put fresh RO water with nutes in it? My RO takes an entire day to make what I need. I’ve had to set my alarm in the middle of the night to put the 5 gallon bucket of water into the trash can. The grow in the apartment is so far away from the water source and I don’t think the landlord would be cool with me running new pex line to the room lmao. It’s just such an inconvenient way to get water, but I make it work. With all that being said, what would you do my friend? Thank you for all the advice and taking the time to help me out dude!

The roots looked good Sunday when I was cleaning water out. They are the same brown color as the AN grow. They didn’t look rotten or smell off.

i'd do 2 things for the Mg;
first give them a foliar spray of 1 TBSP of Epsom per gallon. right at lights out is best.
then bump up pH to around 6 to 6.2 and see what happens.

That’s like salt, right? Epsom salt? I haven’t had to change PH yet, so I put two drops in to see what it does. I’ll do it slow if I have to Over the next day. I’ll go get some salt and spray it tonight when the lights go off. Do I soak the leafs really good, or just give them a mist? Seriously, I appreciate your time, thank you.

 

[rkymtnman]

i try to do it about 2 minutes before the lights go out (makes it easier to see what you are doing)

the goal is to spray the leaves especially the underside when the stomata are open. they eventually close shortly after the lights go out. luckily you are still early on in bloom: you don't want to get buds soaking wet and risk mold.

if it looks like this fixes your issue, just start adding 1 gram per gallon along with your nutes
