Hey I posted in your thread..... those plants that are yellow were they just switched to soil or were they in that system?
If you want to grow hydro you MUST have a TDS/PPM pen, there is no exception to unless you know how to grow without one and read your plants......
SAme goes for pH pen too, I would not grow hydro/aero without it dude, seriously.

Your plants have no micros, not enough.

You need cal mag since you are using distilled water..... distilled has nothing in it, it's pure h20

How much of each if using multiple? 1/8 strength iguana juice grow

How much is 1/8 strength with how much water?

 

[donatello22]

Normal strength is 3.5mL to 1L of water so I did a little less than 0.5mL per litre of water which was close to 15mL for my 32L res.

So I should go pickup some calmag....and a ppm pen....what else?

 

[MynameStitch]

Pick up pH pen and make sure you get some calbration solution for the pH pen and TDS pen......

It's nice to have a combo, BUT the downside is if one side goes bad your shit out of luck.
Ya, for those size plants I would have used around 3.5 to 4 ml per gallon of water

so like a little over 1/2 to 3/4 teaspoon per gallon of water.
Trust me on the pH pen and TDS, that will make a whole worlds difference.

alrighty well on Monday (store was closed early today) I am off to buy a tds pen and some pH solution test from the aquarium store because I can't afford both...my local hydro shop isn't cheap! I will also bring a sample of my water to the store and test it there and pickup any other micros or calmag, etc as needed.

Thanks alot stitch you have been of great help...I will keep you updated.

anybody know about a rusty color in the center of fan leafs? any help would be appriciated closest thing is saw was boron but i use marine cuisine with has bone meal for it should be good . thanks

 

[MynameStitch]

THanks don, please keep me updated, would love to hear of an update
I will say if you can't afford both, get a TDS pen, thatway you can keep track of when and when not your burning them, pH test strips will help you, but pH pen is always the best, but since you can't get both, get a TDS pen and some solution.

Well..long story short I haven't been able to get to the hydro shop yet. But the plant showed much improvement after I added both some regular tap water and a light dosing of iguana juice grow. Yesterday though I noticed that the rapidly growing new healthy leaves were again starting to show browning after a few days of nice growth so I added a little bit more nutes (because I went very light in the beginning) and more tap water. This weekend, however, I will make it to the store for calmag, tds pen, and ph drop kit.

Keep you updated stitch...thanks for the help.

couple days ago...new growth was beginning to brown but stopped after nute/water addition.


yesterday...new growth grew out fast but then started to brown again

 

[MynameStitch]

Lower the nutrients, if it started to brown again, lower the amount you gave them, you should only kept the amount you added first time and not again, this is due to them just getting nutrients and you have given them too high of a dosage, so I would add more water to the res if you can to dilute it, but I would be careful as you don't know how much you are diluting it since you don't have a TDS pen yet......

 

[donatello22]

Hey stitch...you sure the reverse is not true? Because it started to brown before I even had any nutrients in the soil....and after a week or two with a mild nute solution in the res so I feel that it may be a lack of a whole bunch of nutrients that causes this. I will give it some time and we'll see what happens.

Cheers mate

Soil always has nutrients in them, weather it's weak or not....
Reverse?

 

[Killacash]

My reverse osmosis has been running off water at like 20 gallons per day far from the 100gpd on the model. Should I get rid of it and use the tap water?

 

[MynameStitch]

Killa, give me some updates on your situation, it's been a while since I talked to you last and I forgot about what is going on with your problem.

Ok well here goes. Last time we talked I was finishing my first kbs run and everything kinda went well at least I thought. I noticed that the finished bud had no high to it. So I blamed it on the finishing week when it was at temps of 120dg. Fast forward to today on my 2nd run and I figured out my problem, I didn't check my ph at all my first run and now that I check it it stays at acidic levels around 3.0-4.0ph. I raise it up just to have it back to acidic the next day. I have 2 questions.

I have vegged the plants, I'm guessing in acidic levels for 2 months, is it too late for them?(The bubba k looks good but the ice has a warpy look to it.)

If I can still save them, I'm guessing I should buy a ph doser? Which costs 700$ by the way.


I might just make my own doser?

oh yeah and how you been?

thanks for the awesome thread stitch
for the thrips, spinosad from montery worked great

Hey Stitch...I know its been a while but I thought I would give you an update/get your feedback.

I finally picked up a TDS/ppm pen, some calmag, and also some fungicide at my hydro store. The clerk called the owner and described my problem and he thought it might be some sort of spot fungus because of the way it was starting in spots that slowly got bigger until most of the leaf was dead so thats what he recommended.

I haven't done any treatment or changes yet but I tested the water and it was at about 6.0 - 6.2 pH and ~450ppm. This seems normal to me and, as you will see in the pics, the plant is growing faster and bigger but the problem seems to still remain but it just isnt keeping up to plant growth anymore.

Have a look.








So is this a cal/mag def - and if so how much calmag should I add. Is it a fungus of sort? Or is it some other def?

As I mentioned before the nutes are in the res at MAX 1/4 strength so I doubt it could be nute burn...especially because its organic nutes (Iguana Juice Grow)

Appreciate the help.

Cheers

This is defiantly not a fungus problem, it would have spread to the entire plant by now if it was.

Also temps and humidity play a role in fungus growth and yours are not favable for fungus growth, check my sig hydro guys do not know crap when it comes to growing cannabis, they always tell the wrong thing to do. The most messed up one was the one in my sig!

The damaged leaves will stay damaged and will get worse but will stop soon. I would try increased it just a little bit, no more than 550PPM, no it is not nute burn at all.
