Ok, thanks for that advice! I will be lowering the ppm when lights come on!!! One quick question, I get the ppm around 1500, I come. Back its @ 1800, and. I never put any more nutes in it, how is that?? How. Does the ppm go up if u never add anything to the water????? This is the big one not. The lst

Well, how I understood it was that the plants are taking in nutes and expelling waste resulting in a rise in PPM. Not near as noticiable during veg unless plants are large and utilize a small rez.

Come on peeps! Don't just look and not comment! Any tips or advice would be appreciated! With y the ppm keeps going up, even though I don't add nutes, could it be waste like pazuzu said?? Thanks

Vape the ppm will rise when your water is used, this takes place because your ppm are to high,
There is a sweet spot you will just have to back off a bit and you will find it. But for a grower
Like me I dont sweat the small stuff when mine goes up 200 over where my target ppm was thats
When I add water as add back and with dilution of water the ppms drop.

Thanks. Hellraizer, but I am ALWAYS adding clean distilled water to the reservoir and adjusting the ppm. I was thinking, maybe since in the begining I had the ppm way to high, the plant has a. Lot of built up nutes in her, so now with the clean water, she is flushing her self, hence the raised ppm?! Idk, just a thought! Thanks again

vape if your flushing lol this is a normal thing due to un-used nuts being used, so when you put plain in and it run through
your medium it washes out the left overs and mixes with the water and blam the ppms go up. I flush 30 every day for 2 weeks
to get my return water to 100ppm/mater basic tap water ppm, this tells me there fully flush and ready to chop.

Your ppm was likely too high to begin with. As hellraiser said. Evaporation (actually evapotranspiration of the plants) will cause the ppm to rise. If your topping off with tap water back to the original water volume in your Rez and it still raising... Then something is amiss.

FYI. Topping off with tap and measuring your ppm is the only way to gauge what your plant is uptaking. I wouldn't advise flushing with straight plain water until harvest time. It's fairly stressful on the plants to rapidly change the concentration gradient between roots and substrate (or solution).

Plants do not exude salts or "toxins" that you would be able to measure with your PPM meter.

I'm not sure what pheno type she is, I had a clone gifted to me, and I'm not flushing the plant to get ready for harvest. I meant trying to flush the high ppm, and get it to normal. They'll b 6 weeks this week

I have had 3 of the 4 phenos and settled on this one I have now. 9-10 weeks seems to be the average and 1 did take 72 days (almost 11 weeks). I have not had the hardcore indica pheno(for Jack) tho, I hear 8-9 weeks on it.

*As far as your ppm my Jack gets burnt tips over 1400ppm, I run about 1250 with same results but no burn. Mine goes up with water loss to plants, other than that no idea.

1250 seems about right. 11 weeks! Holly shit, you have the patience of a saint. I had some super
Lemon haze a couple rounds ago. It was the dankest weed I ever grew, the absolute fire but it was a low yielded AND took 12 weeks. I don't care how dank you are, no 12 week strain will ever step foot in my room again :)

This jack seems. To be right in between, thin like a sativa, bud the nugs are DENSE already. I'm hopin for 9 weeks, but I could wait 11 :) can rush a fine thing! Ill put some root. Pics up wednesday. Say the ppm is @ 1800, I put in 2 clean gallons of water, bring it down 1500, in a day the ppm will b back up to 1800, the plants don't seem to mind the high ppm, the jack likes it, I just don't want to put to much water, and not enough nutes, thanks again

its too high dude. Its high to the point that the plant probably has difficulty uptaking nutrients. I think if you added water to the point that its around 1300 you would see less of a daily jump in PPM. Flushing, and then adding 1800 ppm nutrients is kind of defeating the purpose.

Just as a general rule, no plant needs 1800 PPM. You start getting nutrient antagonism problems when things start getting that concentrated. Trust me and hellraiser, higher than 1400-1500 is fairly abnormal and really, is just a waste of money.

Each cup of nutrients costs several dollars....

I know! Lol, but for some reason it keeps going up, I'm just gonna fill it again with water tonight, check ppm in morning, thanks

Hmmm. Can you give me the details of your grow again? Substrate, number of plants, container size, Rez size and watering schedule. I'm willing to bet that your Rez is just too small given the size and number of plants. Too small of a Rez would result in wild ppm swings but often times, also ph swings.

Cool, I got it down to 1200 tonight, so we will see how it. Goes. I just have. The jack and g13 in one 6 gallon res, I feed when the water gets. Low, no set schedule
