Crazy PH drop and High EC
Jfmart420started grow question 4 years ago
So I mixed a ½ gal solution but adjusted it by adding water to ⅔ gal to bring down the initial EC/ppm testing at around 1400/700. I ph to 5.8 and fed, the runoff was shy of 20% testing at PH 2.65 EC 3940 ppm 1970 Why and how to fix?

Overfeeding. Flush with regular, ph'd water until the runoff is where you want it. With your pH so low, I would run 7-7.5pH until its back where you want.
When you overfeed, the plant takes up water and leaves the nutrients. Most nutrients are acidic so your runoff becomes low pH and high EC.

Hello Jfmart420,
the water runoff pH should not differentiate more than +/-0.5pH from the initial pH water. The ppm value for vegetative phase should be around 450-700. Make sure that the initial pH value is around 6.2-6.5pH and also lower the nutrient concentration a bit.
Good luck with your project, I wish you all the best! 👽

Nitro toxicity and calcium deficiency. Should I flush?Little pas halfway through flower and appears I have nitro toxicity, could this be a cause of my calcium deficiency I have been dealing with? Should I flush it or would that continue the degradation of the calcium?

Flushing or feedingIm already flushing the plant for 2 weeks but as the Trichomes are not changing much it will need some more time to fully develop. I want to see some (10%) amber trichomes.What should I do now? Continue flushing or give some organic nutrients again? Probably need 2 weeks more.Week 25

Nutrient LockoutI'm guessing this is nutrient lockout. Yesterday they were thirsty, so I watered by usual two gallons of aquarium water, but added no other nutrients. It only seems like one plant is being affected. How long should I withhold any nutrients; should I dial back when I do resume?Week 8

First harvestWelcome to the members. It will be my first harvest. How much time do you think you have left? I asked this question a week ago, but the flowers swelled up a lot in a week. Can you leave 2 more weeks? In such a case, should I start washing with only clean water with a pH?Buds. Other

High ppm in drainageI flushed coco two times with 8-10 litres with CalMag (200 ppm) and it does not help. You can see in my comments to the last weeks of the diary that it doesn't matter how much ppm I water the plant, it is always 2-3 times more ppm in drainage.What should I do?a year ago

Watering a auto seedling properly.If you have a seedling 1 week old in a 3 gal pot how do you water I hear watering till run off but wouldn't that be to much as the roots haven't reached the bottom yet? I also se people making a small circle around the seedling or others using spray bottles. I tend to over water.Feeding. Other

Calmag overdoseI was stoned and accidentally added way too much calmag to my distilled water when watering yesterday. I meant to add 2 ml into a gallon but instead added 20 ml. I poured 3 gallons of Distilled water through today trying to dilute. Am I screwed now? Is my plant going to die?Week 4
