I guess there are differing thoughts on this, and as long as your babies are happy and healthy... but here's a Q that's bugged me, like forever...
Is there a 'best' pH (within range) for veg v flower?
I tried to get online on my phone @ work last night to try and find one of those charts that shows the availablity of each nute at different levels... and got caught off guard by this:
""I follow and highly recommend the following parameters for hydroponic nutrient solutions for aeroponic, “bubblers”, drip, ebb and flow, NFT, passive, rockwool and wick systems.
PH 5.1-5.9 (5.2 optimal)
TDS 500-1000ppm, EC .75-1.5
Temperature 68-78f, 20-25c (75f, 24c optimal)
The pH of the nutrient solution is a major determinant of nutrient uptake by the plant. If the pH wanders outside the optimum range of between pH 5.1 and pH 5.9, then nutritional deficiency and/or toxicity problems can occur... For hydroponic nutrient solutions used with inert media, keep the pH at 5.2 for optimal elemental uptake... ""
Okay...
No.
This is not right, and never will be right, maybe the range is CLOSE ENOUGH that iyou wont get any lockouts from your more popular macro nutes- but 5.1 is not even in the soil range.
THIS WAS THE FIRST RESULT IN GOOGLE...on 420 MAGAZINE!!!!! Are you shittin' me???>
I have read SEVERAL paperback books stating 5.8-6.3, for any system of hydroponics
And several books have stated 5.5-6.5, for soil. (I cant confirm this one with exp.)
PLEASE malevolence, dawg, someone!! confirm or deny with me! Testify against these 420 wannabes!
I believe it was brother dawg who also told me that he noticed that Sativa/Sat dominant strains seem to enjoy a higher range- I cant seem to get my ph to hold, but I see this to be true when I CAN get it to stick to 6.3, even 6.5 for a while
EDIT: and this guy is BEING PRAISED!!! Pucking christ... and 2 posts. Good for you, dumbass.
