I was wondering if anyone uses this stuff every watering as recommended on the container? I have been doing so at reduced dosages, but i was wondering if i should start becoming concerned of fert burn. Can you burn a plant with too much phosphorus?
You would really need to have added Hydrated Lime into your soil in order for you to use PBP because its quite acidic.And by having Lime in your soil it balances out the pH for nutrient uptake.
but my pH is right at 7.0 but i did notice slight little burns at the lower leaves, but i think it is from the liquid karma i used during the last feeding. So what can happen if i don't have the hydrated lime? i mean the plant looks great, but i still want your opinion.
What if i started watering with some calcium carbonate? would this help maintain the PH? i haven't had any changes in my pH. I used Peruvian seabird guano throughout veg and early flowering and i am now using indonisian bat guano along with liquid Karma. I also have pH adjuster; so if the PBP drops the pH, can i just keep bringing it back up with my pH adjuster?
I would keep the pH at 6.5-6.8 during early flowering and by the way i use Organic pH Down and Hydrated Lime for adjusting,use the LK every other week.
thanks hellboy, i'm almost 4 weeks into flowering, so would you recommend using some calcium carbonate when i water?
Oh yeah, how much should i use and also could you give me your soil mixture recipe that you use? (Edited by chato420 at 5:26 am on July 27, 2005)
My soil mixture consists of 50% Fox Farms Ocean Forest Soil, 20% Coco Coir, 20% Perlite and 10% Compost.
If your ph is at 7 then you are good. Too much haggling over a couple of tenths by some growers in my opinion. MJ is not that picky. Just my opinion.
