Caused by water temp?

GotADAB305 said:

Hey guys, just have a question. I know my water temp is extremely high, and am currently working on the solution for that.

But my question is can these brown spots be caused by the water temp?
My PH was over 6.5 yesterday and I have gotten that under control.


What would be other symptoms?

Water temp between 78 f and 82 f
Room temp avg 78f
Humidity between 50 and 60%
Ph 6.3
Ppm 431

Setup:

15 plants in a DWC, with top-feed
2 fans
4 led lights (1000w)
1 600w hps, waiting on my mh bulbs
Light 18/6

Got the clones at about 22 days old.

Put them in the buckets on Friday

**will take pics with out the lights on when I get home, I apologize.

TIA

To answer your question, yes. To hot of water could cause root rot and could cause poor nutrient uptake. Then that could cause all the nutrient deficiency's you have. And if your light is to close it could cause you to cook your roots in the hydroton, even if your water temp is within limits, itll cook it between feedings.

I would rethink your lighting as they dont need a 1k on it or at least raise it up. way up. You want to slow the grow till you get your shit together. Hydrogaurd would help you right now. and what did the roots look like when you put them in friday. pull one out and look at the roots what do they look like now.

you could freeze 2 liter pop bottles and put those in your res a couple times a day to get the heat down. You could wrap your rez with insulation to keep the cold in and the heat off your rez. I use the 55 gal blue barrels and those hot water tank insulation you get at the home improvement stores wrapped around my barrels and I did notice a difference with how much my chiller had to run to keep the temp.

Totally unbelievable you want to get some hydroguard in there asap. Honestly I dont know the dwc system you have or how you have it set up. With the small tubs and air stones and top feeding its the fastest system not the best imo. I have the titan ebb and flow system, but growing is growing. I learned from the dirt side and just applied whats applicable to my system. A plant is a plant. You dont want to run nuted water through your chiller. In my system I have a barrel of water that the chiller chills and a pump in that, that pumps chilled water to my nuted rez and in that nuted rez I have a wort cooler made out of stainless steel. [Do not use copper tubing or copper anything in your system.} And the water runs through the wort cooler and cools my nuted water so I dont have any nutes running through my expensive chiller corroding things up or leaving nuted slime in my chiller clogging things up. I actually had my wort cooler kind of custom made to what size I wanted they look something like this, I dont use those type of hose connectors I just used the hose and some band clamps. https://www.northernbrewer.com/silver-serpenttm-stainless-steel-immersion-wort-chiller?gclid=EAIaIQobChMIu_q_hfnI2QIVhYTICh07gAc8EAkYFCABEgK9ZvD_BwE and you can get them at a store that sells beer making stuff. Your going to want to get at least a 1/4 horse chiller anything smaller probably wont be able to keep up with the cooling and just keep running, their not cheap and dont cheap out on this piece of equipment. and dont buy a cheap one get quality research this. and that ballast sitting right next to your pot making the side of the pot hot you need to move that. Get all of your lighting cords off of the ground and hung up proper. and the way that hood is mounted where the hooks are attached looks bat shit crazy to me. Not exactly level at all.

Good luck. Hope that helps.

Also, how much bubbles should I see in the bucket? The first day when I put the air stones in it was bubbling crazy.

When I lifted them today, they are not bubbling as much. Is it because of the temp it's not bubbling?

That cobra product is what you need to use. That is the microbes foaming up. Since there not as foamy they are dying off which they will do in these kinds of hydroponics systems. I believe they do like a temperature more than others but I dont know what that is and probably not what your temp is at. Maybe use that cobra at a quarter strength every four to five days. Dont know how much you added at first but it doesnt need to be too foamy just need a constant active microbe population in there helping the roots. Less is more. And if you can dip out of your rez every couple of days and top feed your plants to make sure that the roots get a complete wetting would help.

What do your roots look like?

I have learned over the years its best to stick with one barnd of nutes as this way theu play well together.


Looks like a deficiency or lockout possibly high ph? Iron, mag . Cant remember which deficiency
Causes yellow on new growth

Look it up on a deficiency chart

I have a top fees drip system feeding them. But the pump is off until I get the temp fixed.

I just picked up an artica water chiller, although it's only 1/10th hp, It should be good for the amount of water I have in the system. And it only cost me 100 bucks. Going to clean it overnight and install it first thing in the morning.

Should be back on track tomorrow.

Thanks again for all your help man.

You said that the little chiller would be big enough for your system but you have 2 50 gallon drums you use to mix the water before you add to the rez? So do you mix up a big batch and just leave it sit there all week. With the cobra product in it? All your microbes will die if you do that then its 14 tbsp of waste. I would just do a water change and add nutes to your rez and just use the 50's for storing plain water. That's what I do.

also

This is what i do== When I do a water change I feed my plants with the fresh batch, I dip out 2 - 2 1/2 gallons of nuted water out of the rez I add 1/8 tsp of my powdered microbe product and 10ml of molasses. I reach in there and mix it up at the bottom as the molasses will fall and stick to the bottom of the bucket and then while my pots are full {ebb and flow} I will top feed all my pots with the microbed nutes and it gets on all of my roots this way while the pots are full. Then its business as usual and the pots drain back into my rez I get a little foam on top of my rez from the microbes mixing back in. Im good. I dont waste a lot of microbe product this way I get total coverage of my roots and my roots have been looking pretty sweet doing it this way. I use the RAW brand microbes and GW till that runs out then its all RAW microbes. My brand doesnt have the b-1 or humic in it, I add that stuff separate if I want. So If you try your brand this way you wont be getting much of the humic and kelp and b-1 thats in your brand. I use the RAW brand cuz they have a separate grow and bloom microbe product. I also have the hydrogaurd but I might not be using that any more as the Raw brand has a high cfu of whats in the hydrogaurd.

Yea the chiller is good, it took almost 24hrs yo bring down the temps to about 65f. But I'm back at reasonable temps.

Also I found another problem. Since my clones were in Rockwool cubes (3") and I was top feeding the cubes were soaked.

I have since moved the drip to just allow the water to circulate.

My question Is do I squeeze the cubes to get the extra moisture out, or just let it drain on it's own?

Tomorrow I will be doing a water change as well.

I used the two 50 gallon to mix yes. And out of that I use about 75 gallons.

Didn't know about letting the microbes sit there and die. I will be following your tips.

Drain on its own cuz you dont want to damage the roots. Yes having the rockwool getting wetted everyday isn't good for the plants. Got to let them dry a little. {When I do rockwool clones and they go into bigger pots I make sure that the bottom of the rockwool is at the top of my full line in my pots so they dont keep getting wet.and just the roots get wetted.I also top feed at this time so that the rockwool doesn't get too dry also.} Just like the dirt guys. I have done that mistake before. They say you shouldn't or don't need to add microbes in hydroponics as all of the nutrients are readily available to the plants. I use them as its what nature does and it helps keep the bad bacteria away from my plants-root rot. Yeah they just drown and die or die on their own, an air stone will help keep them alive but I don't use an air stone. I just add every water change.
