[borax]

Hi guys!someone is tuned?I measured the pH at this time and in both buckets is increased from 5.7 to 6.7.It icreased in only 7 hours!in both buckets !!!what's going on?Is nitric acid doing this?i remember that with phosphoric acid the pH remained more stable.there is a connection with the value of EC?Need some help!!Tell me...I'm all ears!

borax,may i make a suggestion contact a mod and get your thread moved to the new hydro section,youll get a lot more help there and as kindred said check out seymour he is the master at dwcsj

 

[borax]

Thanks for the advice.I'll do it

growing 2 plants in the same bucket is not good practice unless they are clones, im not saying its impossible to do but it will be a ball ache especially if they both want different feeds which is probably why you have ph swings

when you make a res change and adjust the ph into range you should wait 1 hour and check the ph again to re-adjust, i use ph down that contains sulphuric phoshporus all the way through the grow with no ill effects i understand the nitric acid for veg but in veg you ph should be 5.6-5.7 then when they show sex move it to 5.8

you have the same background ec as me and by week 3 you should be on 1.6 ec, im pretty sure you are feeding your plants in equal amounts of micro/grow/bloom with 30ml of rhizotonic

double check the accuracy of your ph pen by making sure its configured properly

also another good indicator of ph and ec movement is the temprature of your water, if your using cold water on your res change as it warms up inside your grow room the ph an ec will alter, your res temps need to be between 65-75 degrees

these are just a few pointers for you to check out, if you do all those checks and the problem is still there get back to me

Hello Seymour! Thanks for reply.Your influence has stabilized the pH at ... Joking aside, I just checked and it was 5.8.
When the problem of fixing pH came up, the plants were already in two different buckets, except for two TD (I think being the same strain, they need the same amount of EC), one large and one small, which has lagged behind for different reasons but is recovering.
If the pH does not remain stable in the coming hours will return phosphoric acid and take your advice for the next fresh res.
As for the power I'm not using the same amount grow / bloom / micro, but I am following the dosage on the bottle that is 15 ml grow, bloom 7.5, 7.5 micro in 10 liters of tap water and I'm not using rhizotonic but a 1ml/1l of roots stimulator. These Are the doses recommended for the growth phase. But if you advise me to use the same amount of all three, I do. I'll use also rhizotonic if can help me.Keep in mind that today the palnts showed sex and are females. I take this opportunity to ask to you at which point of the growth I have to stop giving the grow,if I do, and keep only bloom and micro.The EC of AutoMazar is 1.5 and TD is 1.6 (just measured and I noticed a small decrease of about 0.1 Both plant that I can not interpret). The pH and EC pens were calibrated a few days ago.
I use always cool water and Since I covered the buckets with aluminum foil the water temperature has dropped or however remained fresh for a long time than before (I don't have a thermometer but use my finger for now .. lol) but I know I have to fix it someway.

same strain doesnt mean same ec cause you can get different phenos, when doing a fresh res change you have to wait for the ph to remain stable, you can do an experiment with a fresh batch of nutrients and set the ph then return 30mins - 1hour later and the ph will have risen, you just have to keep adjusting till it remains in the desired range, after a few grows you can gauge where you want it to be, i know that if i set my bucket to 5.5 it will stay stable at 5.8 but thats just experience

as stated i use phosphoric acid as ph down and it makes no difference

when to switch to bloom nutrients is the million dollar question with dwc, soil growers like to switch to bloom feed when the plants have finished stretching so they can get as much growth as possible but with dwc you have to be more cautious otherwise shit will get out of hand in terms of plant size, ill give you a few examples of the choices you have bearing in mind the stretch period will last for about 2 more res changes

1, you can keep her on full grow / bloom / micro untill they have stopped stretching and then flip them over to bloom nutrients (WARNING the mazar loves nitrogen and to much could delay her bloom onset,ive been there lol)

2, next res change give them equal amounts of g/b/m then on the next res change give them half grow but increase the bloom and micro to maintain ec

3 next res change give them half grow and increase bloom and micro to correct ec, next res change drop the grow and increase bloom and micro to desired ec

choose carefully otherwise you will out grow your tent

with hydro your in the driving seat and their isnt any right or wrong way to do stuff its purely upto you on how you grow your plants

good luck, not that you will need it from the info i just gave you lol

Thank YouWhat a ledgend !.just the one TD or AM would outgrow a 80x80 tent if grown nearly as well as Seymour does !! I think i'll switch to bloom early with my small cab.

Hey Borax, you got nice looking ladies in your tent and you'll be reward with some primo buds soon, Both of those strains are known for for out growing tents, not too mention when they get really big changing the Res by yourself can also get diff. Good luck with your Grow

3 next res change give them half grow and increase bloom and micro to correct ec, next res change drop the grow and increase bloom and micro to desired ec

I think I will change the solution in 4 days, so I have some time to consider which option to choose. My growroom is only 1.60 m high and I grow with an agro hps lamp 250w, and we know how it could end up with the size of the plants and their proximity to the lamp. However I'm oriented towards the second and the third option.

good luck, not that you will need it from the info i just gave you lol

Seymour you are a PRO and I am confident that by following your advice of experience, I can achieve good results, me as others.Thank you Seymour!

Hope you can fix your PH issues, I know of my own experience how annoying it can be (I'm still facing it, need to adjust ph 2 times a day....). Listen to SB and everything will be oke.
