So you think its all the beneficial fungi and bacteria eating the sugars and upping the PH?
My PPM stays amazingly stable. I use 1000 ppm or 1200 ppm and the PPM does not drift more than 100ppm in 2 weeks. It almost seems hard to believe that when there is only 10 gallons left it is still at 1250ppm.
But seriously it sounds like you are running a heavy salt solution and your plants roots are not using it all. How is the PPM flux in your res?
because drip emitters can get clogged an I like to keep it simple. Would drip be better? I read somewhere that when coco dries it ups the ph? Is this why?
Hmm... Is it not already right?
Nutrient concentration is dependent on plant strain, size and many other environmental factors. For example Ak-47 will not tolerate the same nutrient levels as White Widow. Here is a good guide to determine what nutrient concentration you should be running.NEWGROWTH! Nice thread bro.. I was curious ive seen and heard alot of things and im really tightening down my grow. My question is what are the actuall ppm levels people should strive for in the different stages especially latter stages of flower?
Any help would be appreciated
Maybe, I have not worked with coco myself and have limited experience with organic hydro, it was just too frustrating and unpredictable to me.
Well eliminate that possibility
Its possible but I always thought quality coco-coir was treated and was a rather inert media.
Sounds right to me . . .
I was just wondering, keep the flood table if its working!
The best nutrient brand is the one that works for you. I use Ionic brand nutrients myself. General Hydroponics gives good results.
You Ph should be 5.8 in hrdro
Do you have a PPM meter?
There should be no need to flush the system every two weeks if you are running correct nutrient concentrations. Just change out you solution every two weeks and top of with fresh water between changes.
whats wrong with molasses?The best nutrient brand is the one that works for you. I use Ionic brand nutrients myself. General Hydroponics gives good results.

Do you have a PPM meter? no I use a tester daily. it is not exact. it goes by color.

I would not use molasses either.
Molasses works by providing beneficial microbes with food. Works very well in organic soil grows. In hydro you are asking for trouble, gunked up pumps and microbial nasties taking over. Just keep it clean and simple with H202.
Never heard of Ces, do you have a link? At ten bucks a quart why not try it out though. If it suck you can always use it on your house plants.
Hey man, yes you can make your own water chiller, just pick up 1/4" copper tubing and make a coil. Fit garden hose to either end by attaching fittings and using hose clamps. They sell all this stuff at the hardware store. Then attach one end to running cold water. The cool water flowing through the copper tubes will cool your solution. Someone in here was also looking into using a liquid computer cooling kit to drop res temps as well. (I posted this earlier). If you are on a budget freeze a bunch of water bottles and drop them in your res. And yes 82 is too high, the higher the reservoir temps the less oxygen your nutrient solution will hold. These means root rot , not good.
I have read that as long as co2 is at 1500-1700, temps can reach 95 with no detrimental effects. infact they say to run higher temps 90-95 with higher humidity as high as 95%. the humidty seems high to me so I keep it in the mid 60s. I will drop the temps to 84-88Hey man, yes you can make your own water chiller, just pick up 1/4" copper tubing and make a coil.

These means root rot , not good. so even when its a flood and drain? the roots stay sitting in clay with no water just air, then get wtaer for 20min and drain again.they are feeding 4 times a day. so they get about 5+ hrs inbetween feeding with just air. hydroton doesnt hold any water.
Sounds like you need some heat control too 90F is pushing the limit.
You are correct I forgot you had a flood a drain with hydroton. You can have higher temps with CO2 yes. Slightly higher temps with CO2 80's seem to give even better growth as well. Its interesting . . .
Sounds good man I have a feeling things are going to progress very well
OK NG here I was just over a month ago and here I am today 2.5 weeks into flowering at the time of the photo.Hey NG. I'm using Ionic Growth right now my plants are 2 red diesels and 2 blue cheeses they are 2.5 weeks old. My ph is 5.8 and ec is 2.6 my tap water has a ppm of 550. The lower leaves had some heat stress at first as well as some nute burn I think. I have changed my reservoir at 2 weeks when the ph rose to 6.3. I hear you talking about a two part ionic series. Do you mean the Ionic Growth and the Ionic Bloom? Do you use the Boost?
Any comments on the plants would be greatly appreciated.
Thanks man you ROCK!!!!
I just add it when I change my rez every two weeks. If I run into serious problems high concentrations can help clean out the rez 10ml/L but notmally its just 35% @ 1.7ml/L everytime I change the rez out. You can add it every week if the roots look unhealthy.
Nice looking plants.
I'm not sure what you mean. Change out your nutrient solution completely every two weeks and top off with fresh PH adjusted water in between changes.Hey NG,
I have a quick question. Whats the best way to "flush my AG res.? It's been almost 3 weeks and I need to flush it I believe, to make sure nothing is clogged up or anyhting growing in their. Thanks
