Maintaining the soil pH
GrowmieDeLaStreetstarted grow question 3 years ago
I give pH'ed water, never more than 800ppm and I still always end up with lockouts. I used to not give water untill runoff but now I do. What to do after testing the runoff? It's currently at 6.0 even after a flush with 7.2. Ask many questions I need to know what I'm doing wrong.

Well 6.0 to 7.0 is the range for soil ph. Don't water past 7.0 mph water. Soil holds your nutes, so you should only be feeding once in a week or 2 if you can get away with it. When you check soils ph and ec from the runoff, you need to check the very first drippings that comes out. Soil grows aren't like coco and such that needs food every feed. 6.0 is ok to be at with soil. 6.5 is best throughout a soil grow. Just plain water until you see all new growth is green and healthy again, before adding nutrients.

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

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

PH-Problems in SoilBefore repotting, the pH value in the soil has always fallen to below 5.5. The plants always have an iron deficiency. I then repotted the plants and that worked well for 14 days. Now they are showing PH deficits again. The soil has PH 5,4 -4,8. What could be the reason?
