Advanced Nutrients Grow, Micro, Bloom?????

.................................

Change water every week is ideal, but you can go 2 weeks. Did you put 55 gallons in the calculator? I'm getting 28.13 fl oz each.

I put 40 gallons in the calc and it says 20.42 fl oz each of grow,micro,bloom EACH WEEK.

That's what they recommend, but you can go half and get great results. Plus you'll have less chances to burn anything by accident...

alright can i just use 5-8ml/gal? so 15-24ml of grow,micro,bloom combined/gal of water? or 600ml - 960ml combined (gmb) to fill the whole 40gal res?

It would be 15-24ml combined in the Res every week. Clean out in a week and then put another 15-24ml combined for the 40gal of water in the Res. Don't forget to use at least Big Bud and Bud Candy when time the comes...

check your ppms and dail yourself in. without checking those, you are just growing blind.

Yes, you can't just read the package and assume everything is right. You need to listen to your plants and see what they do when you give them the nutes.

Personally, I've found the Sensi A&B is a better choice than the Grow-Micro-Bloom, but if you want to use the three part system, use less than you think you need to use. So much easier to correct having too few nutes than to correct having too many.

Add in some Voodoo Juice, B-52, Overdrive, and Big Bud and you've got a powerhouse of nutes from Advanced Nutrients.

how many plants/gallon do you have? That will ultimately determine how long before rez changes. My rez gets totally jank by day 8-10 and I have 3 gallons/plant.
Just make sure you add some nutes when you top off the rez throughout the week. Especially micro nutes like iron that have the chance to precipitate out. now you are seeing why some growers diss on AV. That shit is fucking expensive.

i change the water once it turns back clear. using gh 3 part.

my thoughts are since the micro is heavily tinted, once the tint is gone from the res so are the micro nutes.

after a week my res is looking pretty clear, so i take that as a sign to change and re-up on nutes.

of course if oyu have 100 gallons and one plant...the water changes should last longer.

you should change the water once a week or every other, and top with durign the week with straight water. i dont like doing add-backs mid week.

you never know what the plants are using, so by doing add backs you are changing the ratio of whats available. and it seems availability in the correct ratio is key.

the ratios get all out of wack you start locking shit out. and even though there may be plenty of NUTE X in teh water, it may not be available.

google lucas addback calculator. but basically just mix up full strength water then dump it in. {your overall ppm will slip a little, but you shouldnt have to do this too many times between res changes}

i top with water, not nutes. because again, you are changing the ratios by adding back and this has caused me stoner math issues in the past.
