Desperate For Advice On Ph Issues In Small 2 Gallon Reservoir

[EventHorizan]

OK thanks I guess I will just order it from there. It'll probably take a week to get it from them though??

Here's the CNS17 I found on Amazon:

Yep that is it.. but hold on cause I have a few other questions for you..

 

[EventHorizan]

I got the entire set up from a friend of a friend for $200. But ya the basic box sells for about $800 with everything, and goes up from there if you get the bigger ones.

ya ive seen them.. Good boy for not paying a stack.. thats pure nonsense.
You know we aint gonna be growing trees in there right?

Is this it?
And do you have a ph or a ppm meter and do you know how to use them?

 

[EventHorizan]

oh ya, I can help you.. bluelab meter!!! We can do this.. I will need your weight set after I teach you my craft! :)

 

[EventHorizan]

it looks like you got 2 totes.. The one your plants are in, then one underneath?
btw your meter is worth a 100 so you didnt get beat! Im not much for that lil box but your meter is professional grade and that means a lot..
Next summer you will sell the box and buy a tent, I promise you :)

OK here are some pics. First 2 pics show the basic set up ...

This next pic shows the current ambient air temperature in the room, and also shows that my temp gauge are temp gun are almost identical/accurate ...

Next pic shows the bluelab monitor, showing 520 ppm, 66 degree water temp, and 6.2 pH. I just added a bunch of neutral distilled water to raise the water level to the bottom of the net pot, which is why the ppm is lower than the ~600 or so that I've mentioned in my previous posts ...

Next pics shows that the back wall of the box is currently 74.5 degrees F based on the temp gun, and 75.2 based on the temp gauge ...

Next pic shows that the temp of the res itself is currently 64.2 F ...

Next pic shows that the surface of the res in the "shade" (red dot next to the net pot) is 71.5 F ...

And the last pic shows a leaf temp of 73.5F ...

So regarding the temperature issue, if everything in the box is between 70-80 degrees, including the plant leaves themselves, I just don't see how it can be "too cold".

The bottom "tote" is just a container filled with my kids legos I used to raise up the res a bit. The res probably holds 5 gallons total but with the water level touching the bottom of the net pots now it's about 3 gals of solution.

FYI I also bought a bluelab pH controller that just showed up today, but since it seems like my problem isn't really pH or phosphorus related I'll probably hold off on setting it up.

not as much leaf temp as water temp on roots. Anything under 60 will cause problems, and anything over 70 will cause problems. To battle temps over 70, we use the +life..
You said your ppm was at 600?
Well that is a little high imo for the situation(cfl bulbs), but if you drop it then you are gonna drop out of range with your Ca, calcium, and you need to add some calimag. About 1 ml per gal. then 10 ml per gal of cns17.
Without the calcium, you will see brown spots on the leaves.

Im sorry bro, this is a very expensive hobby, and for a min you be spending more than what it would costs to buy herb, but your knowledge and your ability will swing the finaces your way, 6 to 12 months from now..
But its a little rough in the door.. I are ramon noodles for the first few months, but I said if you want it, prove it!
lol I found you can make a lot out of ramon noddles if you have to :)

 

[EventHorizan]

oh.. ok..
Honestly, that 200 watt cfl is good enuf.
I would pull those 2 other 100 watters out..
I show you my mothers under 100 watts of floros

My water temp has been rock solid between 64-70 for a few weeks. It has literally never gone over 70, aside from the very early days when I didn't know better. heisenbubble has been going on and on about my box being too hot, and so I'm just trying to understand how that could possibly be.

I just added those side lights about a week ago, since I got a late start on the training. Since I'm not going to be able to train her "correctly" I figured the extra light from the sides would be good, but those 2 side lights do raise the temp inside the box by about 4-5 degrees.

FYI I can't buy what I'm growing, so I must grow. :)

Ph at 6.2 is to.high.needs to come down.also your ambient temps seem to low man.get them.up to 77 to open the stomatas on the leaves.i think the actual temp in the box is around 71 IMO.not terrible but combined with the beginnings of algae on the roots and cold water can be bad.
The plant is just not photosenthicizing like it should to draw up the nutes.i guarantee if you raise the box temp about 6 degrees that plant will.look completely different in 48 hrs

 

[dsiomtw]

Understood. It's only 6.2 now because I added some neutral distilled water to bring the water level up to the bottom of the net pots as you suggested, and I just haven't brought it back down yet. I've been letting the pH drift from 5.6 - 6.1 every day, then downing back to 5.6.

For what it's worth regarding the temperatures, I've already tested this and 5 degrees makes no difference. Until last week the room was kept at 72 degrees, which yielded an average temp of about 82 inside the box. Someone suggested that was too hot, so I changed things up and dropped the ambient room temp to around 65-66 which dropped the temp in the box about the same amount, and it literally made no difference at all. My plant looks the same as it did a week ago, just bigger.

What is so hard to understand if your water temp is below 70 and the water is sitting in your grow space the box temperature CAN NOT be that much higher..put a glass of water in your room.see what the room.temp is and.now see what the water temp.of the glass will be.its NOT going to be 10 degrees colder man.its just not.
I think your numbers are off.either your res temp is warmer than your saying or your box temp is colder than your thinking it is.

Ok, well understood..
Is the room controlled with the rest of your house?
Ya training will be key to yield, but I wouldnt get carried away with that right now. This is your first grow right??
I would just run the plants lifecycle once so you can get a feel for it..

im not so concerned with your temps. What is the daily lights off and lights on rh like? Highs and lows?

 

[heisen]

I know this because my plants that sit on the edge where my a.c. blows cold air will look just like that.exactly the way your plant looks.bring the temp up till it says 80 on that wall gauge and you will be in business.those leaves will stand straight out in about 24 hours.also what is your light to dark cycle?I would be at least 20 hours of light right now if I was u.

 

[EventHorizan]

Personally I dont think there is a lot wrong with your plant other than you prob needed some calimag and all them lights prob got you at 5%rh..

are these autos ???

 

[heisen]

are these autos ???

I don' think so but I doubt he' in flip mode at this point.i looked earlier and didn' see anything about auto.the RH is lowthats why I also think his temps are to.low.

 

[dsiomtw]

I just don't think that's true. The res (which is also somewhat insulated) is at the bottom of the box, where it's roughly 65 degrees - the same temperature as the room that the box is in (since the door is open).

The plant is in the upper section of the box, where the lights are and where heat rises to. It makes perfect sense to me that the top of the box is 10 degrees warmer than the bottom of the box, and my temp gun confirms this. And if everything in the top section of the box is around 73-78 according to the temp gun, including the plant itself, it's just not possible that the surrounding air is much colder than that.

What is so hard to understand if your water temp is below 70 and the water is sitting in your grow space the box temperature CAN NOT be that much higher..put a glass of water in your room.see what the room.temp is and.now see what the water temp.of the glass will be.its NOT going to be 10 degrees colder man.its just not.

Said on the gauge 47 percent.i saw that earlier but it prob swings from 30 to 40.My RH is always all over the place from 30 to.99 and never notice any difference untill. flowering.but normally cooler temps will also be low humidity.to me temps are critical for dwc.it is the governor for them.it sets how much they drink.if the temps are cold they get lock jaw and won' drink nothing

 

[dsiomtw]

Yes the room is on central HVAC. Currently I have the vent sealed off though, and with the vent sealed and the door normally closed during the day the room has been staying right around 65. At night with the door closed the room drops to 55-60 so I keep the door to the adjacent room open at night so that the night time temp when the lights are off doesn't drop below 65 or so. According to my temp gauge in the box the coldest it got in there last night was 63.8 degrees during the hours the lights were off.
