So last night i changed my 38 gallon rez and added 8 ml per gallon of Aqua flakes A waited 20 min then added 8ml per gallon of B and let sit for about 45 minutes. At this point the rez's PH was 3.8 so I added about four capfuls or protekt silicone solution to get the PH to 5.7. Then i let sit for about 30 more minutes to make sure it was stable and then added the additives:
15 ml drip clean
38 ml Algen extract
19 ml roots excel
114 ml Multi Zen
So my ph this morning, approximatley 10 hours later is 6.5 and the ppms are at 560 and wheni mixed them they were about 610. I am going to top off with nutrients, but from what most people have told me my PH should have been 5.7 when i woke up after all the adddtives balanced out.
Can anyone share some experience on why my PH is so high this morning. Also water temps are 68 and i got the eco 110l for 18 buckets
Is this after the plants drank it or just sitting overnight?
did you let you water sit over noght with a bubbler before you done any of the above?
Are you using R/O water, R/O water has no buffers in it, and it can swing all over the place, also i normally find that potassium silicate will continue to raise the ph after adding it, normally if i add potassium silicate i go with less and wait for it to rise before adjusting. Just my 2cents, hope it helps!
Is there a reason why you don't use regular ph up? Try adjusting with regular ph up(potassium hydroxide) and see what happens. One thing you have to realize with R/O water is it will swing which ever way is stronger, if you have more alkaline in there it will swing that way. R/O is one of those things you have to constantly watch. Some times i'll get a de-chlorinizer and use 60% R/O and 40% dechlorinated water so that i got some buffer in there and i don't have to deal with the big swings.
i dealt with the big swings at first and one of the main things i noticed was that when my ppm's were to high my ph would go up if its to low my ph would go down. im running r/o water and now that i keep my ppm's where my plants like it my ph stays pretty damn consistent. hope this helps a lil bit
Aren't the House & Garden additives supposed to play tricks with pH for a little while after they're added? I believe I've seen H&G recommend adding Aqua Flakes, pH balancing, and *then* adding their line of additives for that reason. :thinking
I see you said you use RO water but no mention of calmag in your nutes. Some of the buffering comes from that...
Also if you dont have one already a recirculating pump works wonders....
The reason I asked if it was after a drink is because its normal for that to happen. They take acidic nutes out of the water which makes the rez more alkali.
Now thats out of the way....I read this post earlier in the day and lucky for you i was doing a rez change. I decided to checked PH as you did and i ended up with 4.5 and 1000PPM after AF A+B
I didnt adjust PH.....I then added my additives and topped of the rez to the fill mark.
I let it sit for 5 mins and checked it:
PH 5.8
PPM 1000PPM
(no PH up or down)
Hope this helps....
do you do this with aqua flakes? I might give it a try next rez change, and i use the pro tekt for the silicone.... is there a reason not to use it over regluar PH up?
is this with aqua flakes or another nutrients?
I just find it easier to mix 30%-40% of dechlorinized water to your r/o mixture and it saves some headaches of ph gemlins.
...........
also, for the record, stay away from cal/mag unless your plant is specifically SCREAMING at you to give her some... Reason being is most nutrient brands are manufactured and feed charts ARE based off of RO water...mostly 000-001ppm source...
with that said, House & Garden has put 11-12% of cal/mag in the "a" bottle of all its nutrients...so there is PLENTY of it in there, REGARDLESS if you are using RO water.
.......
i would be curious to know what your ph is now after the additives balanced out over the day
I cant pinpoint as to what you are specifically talking about because from your words... "Aqua Flakes A & B clearly did *not* have everything that my plants needed while running in RO" is too vague... but you mentioned RO water...that sparks or brings to mind or makes me think you are referencing cal/mag, no?
then you have situation numero dos....where folks arent actually feeding the plant enough of the House & Garden nutes. Thus they will see minor def. in their plant.
situation numero tres if im growing multiple plants and i only see one or 2 plants have a def, i will foilar feed.... hell even if all of them have a def and its minor and i dont want to change the res...ill foliar feed. I really didnt like any types of foliar feeding cuz i didnt think the messyness outweighted the pro's....that was until i tried magic green...that shit is like leaf crack.
