What is this?

Ok so the tds of my tap water is 140 and the tds of the nutrients is only 570 minus the 140 so only 430. Based on that info looks like I need to up the nutrients quite a bit, probably up it to 5ml of the foliage pro. I see most people are at the 1200-1500 mark.

Did you test a cup of runoff? You know, check the ppm of plain water, water and catch runoff, then check again?
Yeah sounds a little low, but doesn't exactly look like underfeeding.... hmmm.
Are you able to get an R/O machine? Its not necessary, but is so damn helpful.
I mean any flushing with (well) water (mines probably ~250- 300) vs R/O 0 ppm water. Theres a big difference in effectiveness.
Plus you get to drink R/O 0 ppm water. LOL.

Ok so I checked the ph and tds of the run off and its 5.7 and 435. I just upped it to 600. Which is 5ml of the foliage and 5ml of the calmag. I will see what they look like tomorrow and gradually increase to the 1200 mark.

@kushknight I was testing those as you were typing see response above. I was looking into ro just dont have the money right now. Funny how the tds is so low yet the leaves are as green as any healthy plant ive seen. Plus people say to use 1/4 strength but going by this I will need to use full strength to get up to the right levels.

Seems okay if fed recently.
For plants that small I like ~500-800 ppm in the root system on feeding days, not that I actually have a tds meter of my own lol. All this knowledge of technique, and no money to implement it.
And yeah I hear you. R/O is pricey.

1/3 strength or less is generally for feeding every watering. I've even heard 1/2 strength, but don't trust the statement.

Also not sure, but you may be using too much calmag in relation to other nutes. Guess we'll just wait and see lol.

That made me remember. One time i mixed up 5 gallons of water and food, then poured it all through one pot. LMFAO. Stupid soil. Or rather, Stupid KK. :bigjoint:

@Kush Knight Yeah, I was just doing more research and a lot of people say 700 but was going by the "grow a lb in 3 weeks thread where he uses 1500 straight through. I would have bought the nutes he was using just to make it easier but I bought another gallon of the dyna gro literally a day before I started reading his posts. Just built the cloner and got the timer in so I will test that out tomorrow. I will take a few from my father in law and a few from my stock to see what happens. His system seems to simplify everything. Really like the whole ppm thing. Kind of equalizes the amount of nutes to use. The only bad side is I REALLY want to buy another tent now lol. Funny story. My father in law lives literally 1 mile from my house in the same development. I left his house one night with one of his plants in my passenger seat in a tuberware container. I look behind me and think I see a cop car. I get about 50 feet from a stop sign when he puts his lights on! I almost shit myself and had a heart attack at the same time. Turns out he just wanted to get around. Now I really dont want to transport any plants.

Not pulling anything out of my ass. I would venture to guess 75% of all people that grow use HPS from seed to weed. Seeing as how most casual growers buy an out-of-the-box HPS system and run with it, I wouldn't see that number being off at all. I would venture to guess if you stuck up a poll, a good 25-40% of this forum alone grows with HPS from seed to weed. Probably more than that.

maybe 20% I'll do a poll

some deficiency probably. I'd increase to at least 800 ppm over two feeds, air the water and don't go to hard on the calmag also how often are they flushed I go every third water

While waiting, the thought of Zn + P + chlorine crossed my mind. But I SUCK at deficiencies.
I heard him say led needs more calmag, and I had no idea whether that was right or wrong. But yeah, since Calcium and Magnesium are secondary macro's the fact that he was using twice as much calmag as nutes seemed odd to me.

Thanks for the input, he did up his ppm a little, and assuming thats the problem, they should start looking better as early as next lights on, right?

For my 2 cents, my first thought was also chlorine/ other contaminant in your water - if ur not doing so already then run your water thru a filter jug and then leave that filtered water to sit & evaporate for at least 24 or 36 hours.

If u are doing this already then it likely aint chlorine.

@LetsGetCritical With the hempy grow I am watering every other day so flush once a week? With my father in law his plants are about 15" tall and drink the full reservoir (around 30oz) every day. I havent flushed his at all and like I said in the original post his are over twice the height at this point with no deficiencies. I mix all the water/nutrients at my house and bring over to his. So for the first 6 weeks we had the same lights, nutrients, medium, etc. I just switched to led two weeks ago. I just dont get why they are twice as big. I contributed my plant problems to lack of constant fresh air and the led light now. And quick question, if my nutrients are 9-3-6 and another manufacturer are the same but diluted. Is 900ppm giving the same amount of nutrient then? That is my thought process but Im still very new and couldnt find the answer.

@Alexander Supertramp I thought the same as well but I used 5ml of calmag and the symptoms on the affected leaves are getting worse. Is that normal, will they just die off?

@Kush Knight thanks for the continued help, really appreciate it!

@RedWhiteBlueGreen If you didnt see, I am running the same setup at my father in law with the same water, nutes, etc. I am running an led for the last two weeks while he is still using mh. Its probably to do with the led light which should be cal or mag, but Im lost at this point.
