I don't understand. Why do you need PH up? Is it because of the RO water? Does the Mantis not buffer to projected and acceptable levels on it's own? Perplexing ..... Please advise. Thanks.New grow black cherry with mantis using 40 ltrs ro water added mantis till I had 500ppm left mixing in rubbermaid with a circulating pump in it for 35 hours added 4mls ph up to bring it from 5.1 to 5.6
Week 1 veg
Thanks. It seem that with Mantis "Patience" is the nutrient of the day (or two) in regards to time needed for buffer to take effect. I'm currently using Mantis with no additives at all. My plants are loving it and the root zone is blowing my mind. I have only nine plants currently in my Producer and a solid root mass covering the entire reservoir. (kind of like a solid brick of roots). I have concerns about future grows with a full 18 plant crop and the roots thereof. Just as there is a learning curve for use of our boxes in general, dialing in the time frame for Mantis to buffer in each of our individual grow environments is also pertinent. In my experience so far with Mantis, it seems that as long as I have all temps dialed in (reservoir, box grow chamber and grow room) no additives are required. (FYI ... I use tap water.) Mantis is slow to buffer, but it will get there. PH fluctuation will cause leaves to appear as though you need Cal-Mag but as you learn about and become one with Mantis that fluctuation will diminish and as a result the discoloration of leaves will subside in kind. I am adding buffered Mantis weekly as needed based on water level. I have not done any reservoir changes or flushing of any kind. So far I have not noticed any salt or nutrient build ups. No nutrient lock out or burnt leaf tips cause by nutrient build up. The product is working as advertised. My experience thus far is positive and look forward with a glad heart as I continue with my maiden grow with Mantis. Two words people ... Game changer!! Peace and Love.Whitebear gave me some advice he also uses ro water
My tap water here in the uk is 546ppm shockinghi iam just about to start using mantis i have bloombox i use 35ltrs of reverse osmosis water with 0 ppm normally i use Orca Liquid Mycorrhizae @ 5mls per 20L of water . and Sensi Cal-Mag Xtra at a rate of 2ml per litre is this correct or any advice would be appreciatedforum.bcnorthernlights.com
It seem s to work last time ph up from 5.0 to 5.6
It then drifted up to 6.1 and stable
nice and healthy looking. sweet. here are mine at the start of week 7 ....Start wk 2 flower
Just topping up water as required this wk I've topped up twice total 19 lts
Yes, looking good. I think they're happy. I reduced the amount of Mantis a bit. I put 50ml per 3 gallons of water. Not much of a reduction but I felt the "soup" was a bit hot on recommended dosage. Now I want to see the trichomes swell and give me that nice snow look for a Christmas harvest. lol. I really do love this. God bless all of you. Remember, this is fun. Peace and Love. (Oh, FYI, one bottle of Mantis only lasted through week 3 of flower in my Producer. So if using a Producer, have two bottles on hand),They look great
It's caused by PH fluctuation. Mantis is slow to buffer, especially when you first start using it. Make sure your "soup" has experienced a full buffer and the "nutrient mix" has buffered to the 6.1 "goal" before you add it to your reservoir, as suggested by the manufacturer. I have found that Mantis buffers better once your mixing tub and reservoir has acclimated to the use thereof. So, what I am suggesting is that the more you use Mantis in a particular container you create an environment (a thin coating of your container that helps insulate and preserve the Mantis). Understanding PH and why it fluctuates is important when using Mantis.The mantis comes off as making the plants seem yellowish in the leaves? or less lush? .... have you guys felt like that?
It freaked me out on the last run and I didn't finish my test run.
