I’ve been flushing for 2 weeks. At what TDS runoff level do you harvest the plant?
The_Good_Twinstarted grow question 3 years ago
I’ve been flushing my plant with properly pH’ed water for the last 2 weeks. Today the TDS runoff was 530 ppm. What is the appropriate TDS level to reach BEFORE harvesting the plant? What is a good TDS runoff level to determine if it’s good to harvest or not?

I’m rescinding the question. I decided to go ahead and harvest the plant, which is currently hanging up to dry. My TDS had decreased from almost 3000 ppm at the beginning to 530 ppm at the two week flush point. I asked the owner of a hydroponics shop in my town, and he said that I should be good to go, so I did. I appreciate the grower “hashy” for his or her response to my question. Thank you.

I usually do it until I see consistent levels. When mine gets to about an Ec of 0.4 it will hang at that for a while and not really go down anymore. That usually takes about a week to week and a half. Then I'll use distilled water for a few waterings and this will usually get it down to Ec 0.3 and then it's been usually 2 weeks and I'm happy to chop.

Feeding After Trauma QuestionI will feed super lightly tomorrow on August 7, but want to what other growers think.
Kaboom toppled over on August 3. I refrained from feeding to allow her time to stabilize and have only watered once since the fall. In your grower opinion, was waiting to feed necessary? thx 😊4 months ago

We have decalcification machine. Should I add Calmag right from the start? How much? (Autoflower in mostly Biobizz Allmix)We have a decalcification machine (natrium based), so I have low magnesium/calcium. People say my soil is low in cal/mag. Should I add Biobizz Calmag on my first watering?(50% of recommendation for autos?) This one looks already droopy, doesn't it? Think I need to water soon.

Questions about wateringI created a 40 ml solution, the instructions say to transplant after the sprout has grown to the top of the plastic cover and the roots are visible through the plug. The question is, is 40 ml of liquid enough for this growth? I think not.
