TDS meter

So I purchased a TDS meter, and of course immediately tested my tap water...

It tested at 120 ppm.

I will have a very hard time getting RO or distilled water, so I'm almost forced to use tap water.

What impact will the existing ppm have on my nutrient mix? Should I weaken my nutrient mix to allow for the solids already in my tap water?

Thanks

EPA's max. contamin. level 500
Unfit for human consumption > 1,000
Agriculture water < 1200
Fresh water 0 - 1 990
Brakish water 0 - 19 900
Atlantic Ocean 43,000 35,000
Sea water up to 50 000

Contaminated drinking water is shown as 500 ppm. My city water is the same as yours (+/- 50 ppm), I filter it down to 5 ppm with my RO, but at the end of each week, because my big ass plant sits atop my reservoirs, I am only able to empty it to a certain level and the rest stays. Just last week I wanted to know how much remained, so I emptied as much as I could with the feed pump, then added 9 more gallons of RO, cycled it for a few minutes through the pump to mix it, then measured and low and behold, it's upwards of 180 PPM. So my starting point before adding my nutes is just under 200.
 
hello all!

got 2 4 11L pot wilma systems and needing to no how many hours a day i have to feed.

it says on the instructions 4 times a day in clay pebbles, my pots are 75% clay pebbles and the other 25% are coco of starting them.

4 times a day for 15 mins each doesnt sound alot?

has anyone ran this system with the same similar pebbles ratio?

thanks.
 
I do 5 times a day, 15 minutes per feed, top feed into rock wool.

Is that what it is? What now?

That's what it is. You can try picking the nanners off carefully.
You are pretty close to harvest anyways, it's up to you if you want to give it another week or more, or you can chop sooner. If the trichs are mostly clear with the odd amber, you will get more of the heady high as compared to couchlock with more amber.
Either way, it's not a total loss, and you can enjoy some fine weed! ;)

thank you sky bound, i will do my net grow in rock wool cubes, just this time they came already in coco about 1L pots.

Because you have coco mixed in with pebbles, you might wish to first seek the advise of some of the very many coco growers on here because the majority of their journals, they only do a mild feeding till they see 10% runoff come out the bottom, and still way less feedings than other traditional hydro grows. Being as though your medium is 75% pebbles, I would think the shear lack of medium to absorb those nutes would mean you need quite a few feedings per day, but with the 25% coco added, this might change everything. Seek additional opinions please before committing.

Thanks. There were too many, so I chopped. After trim, Two main colas will be ok, 4 so-so, and some little ones for hash. I appreciate your vigilance. ..I had read about that, but didn't know what it looked like. She went outside in march, and we're mostly around 90's now. Too much stress. But a great learning experience. Thanks again.

And your learning experience will serve you well in future grows. I'm thinking you are going to enjoy some fine smoke from your harvest this time though! Make sure to give us a smoke report ;)

What do you think she needs this watering
 
Nutes are somethin I am learnin but I started out with this in mind. You can always add more later but you cant get it back if you add too much.
I am really excited about tomorrow its a week since starting flower nutes and they get another feeding tomorrow. They seemed to respond very well to the first feeding. I called the number on the container of flower fuel and asked if the bud candy I havent added yet is ok to use with their product. The guy was super nice and it was just like talkin to one of the experts here except on the phone. He was very familiar with the product even though not theirs and highly recommended it and told me it was pretty popular. Another question I had was frequency of feeding and for my situation he said once a week is fine as long as I follow the directions on the label and dont exceed the recommended amount. I can see him burnin one and tendin his garden while talkin to me. Keepin it cool just under 70. Fluff and adjust things. Upward growth seems to have slowed and I got stuff poppin out everywhere.

I do have a question. Is there a preferred time to feed em? Lights on, lights off, or dont matter?
 
used to use a wilma. I just let the drip irrigation on 24/7. medium was leca. Add an airstone/airpump to the reservoir for better growth

PS! I honestly don't know how often you should water in your media. Never tried to grow in those
 
I have a little ghetto diy grow box and I was wondering if y'all had any ideas on to how I can help my plants more.

I know I need bigger pots and I'm gonna do that soon, also a fan because it gets kinda hot. But it's gonna be a min before I get a led. So any advice? I'm all ears!
 
You need to get those cfl's closer to your babies, what kind of soil are you using? Need drainage holes in your cups so water doesnt sit and stagnate.
 
I got soil from a neighbor for now, what soil should I be using? And I cut holes in the bottom. I had a grow journal but they changed it to frequently asked questions. Most of my grow info is on there.
 
Wassup 420ers ! Not if y'all remember me but i was having nute defs on my Astrodawgs in a 4x4. Long story short, fixed the problem, had a wonderful recovery...... now THRIPS !!! Can't buy anything at the moment so I'm resorting to home remedies. Found something that sounds plausible but not sure of its effects on our beloved plant. This article claims that garlic and hot chili peppers are the key to a "spicy death". Anyone heard of this ? Or suggest something else ? I heard cinnamon can help as well ?!
