ppm

Hi All just recently purchase this book . Anybody experience can tell me about it ? Main question is here no information about ppm when you are feeding your plants . I would appreciate any help in that direction

Today i found that my tap water is 500+ ppm. Is is ok to use bottled water with 191 ppm Ca 68,4 mg/l Mg 4,97 mg/l So 9,46 mg/l is sodium to much? And im useing general hydroponics micro hard water thanks in advance.

Just started growing 3 seeds of borderline extreme fem. One is short, but otherwise normal. The second shows brown tips on fan leaves with a little yellow edge along the brown. The third is loosing it's leaves as though something was digesting the lower half of the leaf blades. I use...

I seem to always find a way to make things more complicated than they need to be, but I'm a whore to accuracy... So it seems to me that going by PPM might be a better option in so far as being accurate in measuring nutrients, thoughts?

Hello all, Here's a quick rundown of what's up: Purple Kush (2 weeks old since cotyledons opened) in soil mix 50/50 FFHP+FFOF w/ 30% perlite. This girl has never been fed nutes other than what's in the soil. She was watered on 02/10/16 w/ distilled water 7.1 pH w/ runoff of 6.09 pH &...

Hey guys this is more so out of curiosity not an "oh shit mother of pearl my plant is dying" thread aha. I was following a journal and he stated that he boils his water. I was curious to see if it lowers ppm's. On the contrary it raises ppm's. Here's the data. Tap water from faucet - 260 ppm...

So I am going to be having a DWC/Top Fed Hydroponics setup soon. I was wondering what the PPM Levels should look like at which stages? A chart would help if you don't have one I usually make my own charts. I will be using General Hydroponics flora series with 3 gallons of solution. I will be...

This is my first coco grow. I planted un-germinated seeds directly into coco 13 days ago. I first lightly fed them w/ 220 ppm Maxicrop liquefied seaweed last night, as they are looking a bit droopy. How often & how much ppm should they be getting at this stage in coco?

I was recently trying to introduce a new nute compound into my hydro system, and was calculating amounts needed. Anyway, I started with amu's in the Periodic Table to source weight info to arrive at my ppm results, and when I compared my results to Mel Frank's in 'Marijuana Grower's Insider...

OK so the situation is that I am monitoring my plant in a Top fed DWC System on a daily basis and up until Monday, the rate of nutrients being consumed was at a fairly predictable Pace, however, since Monday The PPM has been decreasing at an exponential rate. It went from 60-70 PPM's being...

So I drained the tank and added new nutrirnts and water yesterday with a ppm of 429. Checking today it's dropped to 263! The plant is a 27 day old white widow auto flower, I'm keeping the humidity at around 55 percent, feeding it flora nova grow 3.2 ml, superthrive plant vitamins .60 ml and...

A few years back I got few ww x c99 seeds from Femaleseeds.nl and really liked it. Because it was my first time grow of that strain I didn't take any clones from her. After harvesting those two plants I tried to get some information on the strain, but was always given rather vague information...

I'm feeding very low PPM in veg, the plants are trucking along with no real issues that I've been unable to deal with, however I'm wondering how to tell if going higher or lower on the nutrients would be a good idea. I'm sure trial and error would work over time, but I'm looking for some more...

:420: I only spotted this 1 fan leaf. This leaf was midway from the top in a scrog. Dwcr system using GH nutes following the lucas formula with 2ml of cal/mag per gallon. PPM 850-900 and PH is 5.8. 16 days from flip and the strain is OG Kush. :thanks:

I wasn't paying attention at the time and put bloom before gro and im low on the bloom I'm only .5 off I put my reader in it and ppm is 500 I'm week 2 flora series but the water reads 20ppm before any nutes, so that's 480 ppm taking the 20 from the water, I'm kinda new on hydro I wouldn't mind...

I have a 3gal dwc going on with led, I have a baby veg in it and she showed some signs of stress, so I moved her from 24/0 to 18/6 well when I got up this morning my ph was the same but my ppm keeps going down to the 130 and back up to 420-430 I use frozen water bottles to keep my water cool, I...

Hello friends. I have a hypothetical question. If someone were growing 15 medical plants in a 5x5 gorilla tent, hydro superflow 20 under an LED light what might make the nutrients not be up taken by the plants. These plants were absorbing 20 ppm of nutes every day while vegging. This week the...
