PH ajustes milímetricos..?
Txumy2020started grow question 6y ago
Hey, I’d like to know more about feeding and pH. How can I tell if I need to lower the pH a bit or raise it for better nutrient uptake? What’s the difference between 6.0 and 6.5? Does it depend on the growth stages, or is it better to raise or lower it during flowering?

Hello! To answer your question I recommend googling “ph nutrient availability chart” and you will see how plants absorb each nutrient at different ph levels. Then google cannabis nutrient requirements for an insight of requirements at different stages of its life. You will notice that a soil/soilless medium needs to be between 6.2 to 6.8 to maintain nutritional balance at any given stage but you can certainly tweak it as you desire. I hope this better answers your question and enables you to research and understand. Good night! 🍻

In soil 6.2 is perfect for flower. But as long as you are in range, its fine. Dont start chasing ph, itll drive you crazy. Ideally its best to just keep it in range. Your ph will be higher in the morning hours vs dark hours. Its natural for it to flux. A bit. Big swings up or down is bad news.

Your ph is going to flux throughout the day. Each Nutrients are absorbed better at different ph levels. nitrogen absorbs better at 6.0 phosphorus and potassium absorbs better at 6.25.
Hydroponic is 5.5 ideally

Compost tea pHGazillion recipes on line. But my question is about pH. What should the pH be? Is it advised to try and raise or lower it with G.H. up/ down or try silica or lime. Not finding recipes that cover pH adjustment or concerns. I worry about liquids. I've got a bottle of silca blast.

Time to Start FlushingHey guys, I'm writing because I have one mature plant and I'm doubting if it's a good time to start flushing it. Trichomes are starting to look cloudy, but still many are transparent.
Do you think it's time to cut off nutrients ?
Thanks and happy growing !

Potential overfeedingHi, this is my first grow and I'm running synthetic nutes in a biobizz light mix soil. After today's feeding, the run off came with 4000ppm when I usually get 2500-3000. I hear that you're supposed to get that when using part organic soil but 4000 seems problematic. Any ideas?Feeding. Other

How to water whole pot without soaking leaves and flowers?Made mistake of not filling soil to the top of my pot. Is now difficult to get my watering can in under the canopy to evenly water the whole pot. I could drench from above but is it bad for the plant to get nutes directly onto leaves and flowers. Any other tips for even watering?Feeding. Other
