Desperate For Advice On Ph Issues In Small 2 Gallon Reservoir

agreed. set your room at whatever will keep your water temps at 65F.
the clawing is N toxicity so drop your ppm a bit. the rust is mag defic so you might want to add some epsom salts.

a supercloset is a 6 site dwc with a 2 gal reservoir. re-read first post by the OP.
Still if you are having to check PH twice a day something is wrong with your setup, it should be much more stable than that, either you are having evaporation issues, plants drinking too much, or your nutrients are unstable, either way your setup isn't dialed in if you are checking PH every day.

Also i'd advise against putting epsom salts in a hydro rez, there's much better products to use for magnesium supplements that are actually made to go in a hydroponics system.

I'd advise to use a cal/mg supplement such as GH calimagic.

so you want to add more N to a plant with an obvious N toxicity issue?? gotcha. sound advice.

and to the OP, epsom salt is not a problem to use in hydro. it's magnesium sulfate. no different than any other salt in your nutrients for NPK etc.

That's foolish, calimagic barely has any N in it, and magnesium sulfate is terrible for drip lines and hydro pumps and also has zero calcium in it, i can see why you are having to check PH twice a day, stubborn and stupid.

I guess at the end of the day I'm trying to figure out how I can have too much N and not enough Cal/Mag, when I'm following the exact instructions laid out by Technaflora, which are pretty highly regarded nutes as far as I can tell. Maybe my plant just needs more Cal/Mag than most for some reason, but this is exactly why I was thinking that certain nutes were getting "locked out" (perhaps do to all the pH down/phosphorus I've been adding every day).

You don't have a nitrogen problem, if you did your leafs would be much darker green, i wouldn't listen to that guy it's obvious he has no clue what he's talking about if he's using bath salts in his hydro rez and checking PH twice a day.

I don't know if anyone is checking their pH twice a day. I'm the original poster, and I mentioned that my pH drifts from 5.6 to 6.1 in roughly 24 hours, so I personally am adjusting my pH exactly once per day.

I'm using Technaflora nutes, which comes in 9 different bottles, that you use in various combinations at different times. The "CalMag" they provide is called MagiCal, and it contains 2% nitrogen, 3.25% calcium, 1.25% magnesium, and a tiny bit of Iron.

going from 5.5 to 6.1 daily isn't horrible. you should only be adjusting at a max twice daily FYI. once the root ball gets larger, your 2 gal is going to be more like 1 gal which will probably make it swing even more.

if you mean you add salt, i wouldn't use it. will be too much sodium. even more problems.
This other guy was telling you to check PH twice daily, that's retarded he must have something seriously wrong with his setup to have such an unstable PH

This is the first sign of N tox

Recap: How You Know You Have a Nitrogen Toxicity

  • Dark green leaves and foliage
  • Leaf tips turn down, without signs of overwatering.

  • You may notice yellowing on the affected leaves or other signs of nutrient deficiencies as time goes on

  • Nitrogen toxicity is often but not always accompanied by nutrient burn

  • The Claw often seems random, affecting leaves here and there

  • Heat and pH problems will make the clawing worse, as they stress out the plant and lower her defenses, and cause her to drink more water (and uptake more N)

  • As time goes on, the claw leaves will eventually start turning yellow, getting spots, and dying

maybe English is not your native language?? sprechen sie Deutsch?

fyi, mean for your info, you should only adjust pH twice a day. some newbs adjust pH many times a day. just wanted to make sure he/she wasnt'.

If you even have to check PH daily you are doing it wrong, pH is a set it and forget it type thing...you do it once a week when you do rez change....obviously you got some unstable setup if you are checking even daily.

Also bath salts are for the bath tub, nutrients go in your rez.

thanks for proving my point. see pics. clawing, pointing down, etc.

so add more N should fix it. talk about stupid.
You are special kid, his plant has dark leafs and zero burn, first sign of N tox is dark leafs, go check your PH or something.

really, come on dude. why do people use pH monitors, ec monitors that are on 24/7. just cause you are the best grower here, don't think everybody else is as good as you.

i do drain to waste. i check my pH once every 2 weeks

Why such a small res? Its no surprise your adjusting ph so often. Could try bumping up the EC but your still gonna have rapid swings.

They have pH monitors cause they have gigantic setups with hundreds of plants connected to a dositron and a gigantic rez, it's a lot different than doing single buckets.

you got me there.

8th salt on the list for maxibloom, one of the world's most popular nutes

magnesium sulfate aka epsom salts.

stick to making fun of LEDs. you are better at that.
