Hello
Need help with my PH & PPM in my water tank. I mix my nutrients (Jacks 321, Silica & Epsom Salt) with a target PH of 5.8 and PPM of 1,000. Been in the tank about 24 hours.
Just checked my tank and runoff. Do these numbers sound ok. I thought the outflow PPM was usually higher than inflow?
It typically is. Could be anything. Maybe the solids got stuck in the soil?
I wouldnt worry too much unless she shows signs of wear and tear. I know my runoff is always heavier when you start pouring compared to after a gallon has run thru the soil
Your pH is high for this, is your meter calibrated? The plant should be showing symptoms.
Should aim for around 5.8 in veg up to 6.3 in flower.
I would try to reduce your feed in to around 900-1000
Edit again
You don’t have to water to run off each time to desired run off as long as you get the desired run off by the last cycle. It won’t hurt to do that, but you could save some nutrients.
1,000 PPM and 5.8 PH is exactly what I target and is what my reading were when it went into the tank.
The tank readings today are higher as I mentioned. I no longer use an airstone in my tank because some on here said it causes the readings to rise over time.
I have a pump in the tank that pumps water to the top of the tank and drops back in to help circulate the water. Also have a wave maker in the bottom.
Not sure why the readings go up in the tank. I guess I should readjust the tank water again by adding more water to bring down the PPM and then re PH??
Also, I included a picture and think the plant looks ok except I would have thought it would be a little deeper green? **Does the picture look ok to you?
I’ll also see about calibrating my PH and PPM pens tomorrow
pH will drift daily and has to be corrected daily until it stops, if it does. I stopped with air stones and wave makers because you introduce oxygen when you mix adjusting pH. Unnecessary. If it makes you feel better you can leave in the wave make just adjust daily if you have to.
I use general hydroponics up and down. It seems to hold pH for a longer duration than others.
If your goal is 5.8- you can pH to 5.5-5.6 and it will buy you a couple days. If it hits passed 6 I’d pH down again. Im flower 6.0 and let it drift a couple days if you need to. I like to keep flower 6.0-6.3. I use a mud mixer with a paint mixer bit in a 30 gallon reservoir.
If you add water it will change your PPMs then you have a guessing game with nutrients. Often times tap is higher than nutrient solutions, and RO will basically take on the current pH.
I never check runoff numbers with coco-coir when hand watering and my reservoir with autopots i set at 5.8 and it drifts upwards of 6.5 sometimes and I’ve never had any issues.
Coco-coir seems to be very forgiving, at least with the constant bottom feed
I’ve no experience with these halos, they seem wasteful, alot of work and twice the nutrients am i misunderstanding something here
I forget who exactly but one of the mods grows in autopots with coco-coir and doesn’t even test ph, let alone adjust.
I use to adjust mine down when it hit 6.2 and after learning they didn’t ph at all, ive stopped making any adjustments.
Im still not brave enough to go in blind so I set it at 5.8 but they do with no issues
am i misunderstanding something here
