HAPPY SMOKIN EVERYONE!!!

You mix up your water with all nutes or additives and THEN Ph the water.

SO If My Water Is Like 7. Somthing And I Add The Nutes And It Reads Like 4 After Is That Even Possible???.....can Nutes And Additives Bring The Ph Down...so I Need Ph Up Aswell? Lol

im just a bit confused....YEAGH RIGHT!!!

Yes,adding nute's WILL ALWAYS make your ph go up or down,ALWAYS,weather the ph goes up or down depends on what nute's your using & the NPK levels in the nutes ,like allready said ph your water after you add the nute's not before.

so what are some good veg nutes that i could grab next time im at the head shop, theres so many....what will really help?

Oh boy,thats a topic of hot debate.

I personally believe that expensive hydro shop nute's & magic sauces are not worth the cash,i use Peters brand granular ferts with excellent success,right now im trying out a new fert from Shultz in half the plants,so far its working as good as the Peters with zero problems & i am max dosing with both ferts.

High dindy.. basic Micro, Bloom and Grow nutes will always make your ph go down...
there are a few nutes, like silica, that will make your ph go up (alot.. fast!) but not many (I'm not sure of others).

The more nutes one uses, the lower the ph will go; no matter how high the initial ph reading.
And basically the ph is always going to want to go back up if all is well and you aren't using ppms in the 1800-2000 range.

I've been using the Lucas Formula and I use only about 16ml of phup per grow in a 17 gal res.
It is required in the initial 2 weeks the res in operation and after that, once a week I add nutes and the ph goes down .5 or so.
I change the res only at the end of each grow.

Hope this helps.
