lowering Water pH
Jardunnystarted grow question 4 years ago
please does anybody know the easiest and simple way to lower the ph in water? i would use them to watering on my soil plant. my filter RO water is in ph 8.5. some said they would use the citric acid to lower the ph, does it would affect the microorganism and nutrient in soils?

citric acid has always worked well for me my ph also around 8.0, i ph my water everytime i water and never had a problem. Its very cheap aswell dont buy the branded ph up or down you will get way more for your money if you but citric acid granules .👍

I think you can buy blended sulfuric acid (battery acid) from ahrdware store and thats really good pH down. Phosphoric acid that's used as pH down in homebrewing should be also easily obtainable pretty cheap and it's safer to use than sulfuric acid.
Many pH - products are phosphoric acid

And yes, if your pH is too low or too high, it will block the plant from absorbing nutrients, even if they are present.

You can use a ph down solution or just white vinegar 😉to lower your ph to 6.5

Your opinions on when to harvestHi, I'd really like to know your opiniions on harvest. As a newbie I'm still trying to figure out when to chop her down. My goal is a strong psychoactive high with some body relexation (maybe 20% amber?). I think I will give her another week. What do you guys think? Thanks!

Browning stemI just came back after 10 days of holidays and unfortunately my ladies didn’t take well my absence even though they were watered.
One branch was totally withered then checking the stem I realized it was brown in a quite large part.
What is this? How can I save the plant?

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 😊3 months ago

Is it safe to tweak your light cycle times when you flip?I'm getting ready to flip and was hoping to adjust the cycle time when I do. My light is currently on from midnight to 6pm, but would like to switch to 9am-9pm or 11am-11pm to better align with my schedule. Am I safe to adjust or should I keep it at 12am-12pm when I flip? Thanks!Other. General questions
