Ok is 5.0 a good run off number for indoor growing (tent) I’m in veg stage. I know at some point, I heard or read that 5.0 isn’t bad for vegging. Should I flush again or wait?? @Countryboyjvd1971 @garrigan62 I thought I saw a thread, but I can’t find it ---

I thought you were in flower? But no 5.0 is not a good ph for soil. What is your PH going in? If you’re putting in 6.5 and coming out 5.0 that means the PH of your soil is around 4 or 4.5 which is pretty low. In soil you always want your PH to be around 6.2-6.9. How are you measuring runoff? Are you seeing any problems with your plants? ---

In soil, your pH should be between 6.3-6.8, with 6.5 being the sweet spot. ---

@Aolelon yeah but I checked that first, thinking because they were some older growth from the stem breaking could be causing it. There’s a leaf that is kinda crispy and curling. I moved the light over some so it’s not directly over it tonight ---

You should have a grow journal instead of starting several threads/asking for help across several different threads. It’d be so much easier to help you if we could find all your questions in one place. 😀 ---

Agreed. Your light most likely isnt rhe root of the problem, especially on older growth. You should have no problem keeping the COB within 12-14 inches as long as it’s not putting off too much heat. Your ph going in should be 6.2-6.5 while in veg and 6.5-6.9 in flower. If your runoff PH is low you will have to flush with 3x rhe size ofthe pot of PH water. For a 1 gal pot you would need 3 gallons of water. All 3 gallons of water would need to be ph 6.5. Are you using a meter to test runoff. When testing runoff are you collecting the first oz or two that come directly out or the bottom of the plant and using a PH meter to check? ---

You misread my post. I’m currently answering your same question across 2 different posts. I wasn’t being mean. You’ll know when I’m being mean. I was just trying to let you know that it would BENEFIT YOUR GROW if you put all your questions/concerns in one convenient thread. ---

Also make sure the last gallon of of water you flush with has a small amount of nutrients in it. As you want to leave something for your plant. But I agree, you should start a grow journal and post in that, that way we can keep track of your progress more easily and see what you have done already. ---

@Aolelon nope, didn’t know until tonight they made them and honestly I need one. I catch what run off I get as soon as I can but I check with the ph testing up and down stuff. So I should do the tommorrow during lights out or tommorrow night? ---

So how are you testing PH without a meter? What ph up and down stuff? Can you link it? I wouldn’t do anything atm until you can get a PH meter as what you’re using to test with is probably unreliable. ---

Those are nutrients and cant te ph. Do you mean this? [https://www.amazon.com/General-Hydroponics-pH-Control-Kit/dp/B000BNKWZY](https://www.amazon.com/General-Hydroponics-pH-Control-Kit/dp/B000BNKWZY?tag=ilovegrowingm-20) If so you cant test the PH with that, all that does is lower or raise your ph. Unless you have a PH meter you wont know what to lower or raise it to. @Jamie1234 ---

You can make a thread a journal. Just start a new thread called my grow journal and any problems/updates you have would go in there by commenting instead of starting a new thread. I highly suggest buying one of these. You cant know your PH unless you have one.

Well I dont really know how to help you. I am trying to understand how you are getting your ph readings. Maybe if you walked me through the steps on what you do I could understand better. Really buying a meter is a great investment ---
