hi i knw i prlly should have read more of this threads most recent posts to see what you are talkin bout .....

picture is of seedlings that had just been ph fixed ...found out my ph here is like 8.0 and they had been veggin quite slowly for about 2 weeks so you can see why i was tripping they so small and sick


anyways the other pics are same ones 2 weeks later and i have given em general hydro nutes in very small doses

i am still a newbie only been doin this about 18 months but have recently found in my bloom room that i was starving them and was mistaking nute overdose ..when actually they were starving ....

my question is what is acceptable ppm for the plants in both the stages i have pics of

like what ppm for the seedling stage 2 weeks ago and what ppm for now

i use hardwater with around 400 ppm already in it

and 3 part gro, micro,bloom GH

and they are in general hydroponic brand coco coir

ty so much for info

hello all i am starting a new project. it is called an ebb-n-flow, aka flood and drain. i believe i have what i need to get stated with it but i am just gonna ask to see what i am missing if you dont mind? i have a 400w hps, have drains and pump ballast on the way, i also have a milwalkee ph meter (water proof), indoor out door temp digital, digital timer 6 settings, carbon scrubber and fan,hydroton, oneness nutes., cal-mag, ph up and down,and last but not least subculture. now im not starting with a good strain do to first time growing hydro so im starting with some unknow bag seed to see how i do then going to go to super silver haze. so if there is anything i missed can someone let me know please and thanks

hello there hazedaze i just finished building my flood and drain system i went mid range for parts and it ran me about 1,000 usd. that is pretty cheap for that kind of system in my eyes.but for some it may not be the same. ok but any ways thats what i payed if you have any more questions you can ask i will help to the best i can.

Good idea to get the hang of things by following ur friend. When u r comfortable u can start experimenting.

How about some fans. You could cool ur lights, couple of small fans to move the air around ur plants.

Get a digital meter to read ppm.

Use a ro filter to remove impurities from ur water.

Hope that helps and gl.

All right! Hydroponics is what I know, and hydroponics is the way I grow! :bigjoint: ]

Hey man see ya around. Want to give some advice about my 15 babes...all from Seed, hydro, big bud & blueberries. Just transplanted and leaves had already started to turn yellow from bottom up..coming from the veins, about a week ago.

Do you think generally when you buy nutes, you have to ADD in a trace element solution....since the nutes only include Nitrogen, Phosphourous, Potassium, Iron?? Also, do you have a good way of checking PH, easily, cheaply? THANK YOU!!!!!!!

I use botanicare

  • cns 17 grow ... bloom .... ripe
  • silica blast
  • hydro guard
  • liquid karma
  • guardina my
and a compost tea from my hydro store

So yes I do add to the soup.

yea i need to know if the water i use is too hard ....if i use just cold water it is around 400 ppm i use a truncheoun meter and the EC is 0.8 for people that use that measurement .....................

also the ph is bluegreen coming out of the tap also ....so i guess around ph of 7.5 the other day it was 8.0 tho


any help would be cool

I use ebb n flow so my pH measurements are lower than soil. search RIU for "soil pH" and what ppm your water and nutes ought to be.

Need to start some nutes. I like Botanicare CSN 17 as a base to start from. Start out simple and as u get more experience and r more comfortable u can start addinf things like silica blast, liquid karma, etc.

why would you use any other water than cold water? 400ppm is pretty high, that would be a higher ppm then I would use for the first two weeks.

So you used ph down right?

The help you need is to read and heed. Ph down is less than $15.00 a quart. You spent $140.00 for a truncheon, spend the rest.
Coco-coir needs lower ph than soil, around 5.8 and you should use lower amounts of nutes with it. In the late stages of flowering an EC of 2.2 to 2.4 is adequate.
Your next investment should be a ph meter. With the drops you have to ph your water first and then add nutes. The nutes have buffers in them that affect ph. Until you can test the ph after adding nutes you will not be accurate with the ph. VV:blsmoke:

is attempting hydro a dumb idea for someones first grow?

It is very easy. Read about it, follow other peeps gro journals and KISS (keep it simple stoner). As VV said u'll need meters. I also like LARGE reservoirs, they don't require as much adjustments (pH, nutes) as smaller ones. I use a 75 gal res per 2 4x4 trays.

Good luck #9 :blsmoke:

hey all! Im growing in waterfarms with the advance nute sensi 2 part grow and bloom along with sensizyme and having trouble keeping a somewhat stable ph...i bounce from 5.9 up to 7.0 within a day or so...i do adjust it after nutes are added...any ph down products that you recommend that are more stable than the pool store ph minus?

not trying to alarm you but if your ph is jumping that much in one day you have a problem, i dont think its the acid your using. if your ph is at 5.8 (where it needs to be) it should stay that way unless you have a prob like high rez temps or light getting in causing some funk to grow and raise your ph. i went thru the same thing. by the way i use general hydroponics ph down, about $30 a gallon and its strong, one drop in a gallon of water takes the ph down about 0.7 or a whole unit sometimes.

thanks for the response. My res temps are 65 and the cab temp is 74. They stay pretty constant. As for the light getting in, that was the frst thing i made sure wouldnt happen....i've been pretty careful not to overdue anything and set up the cab so id have a stable environment...plenty of air flo, careful monitoring of ppms and all that...my tap water ph is 6.9 and its well water that is better than most...ppm is around 125 ish...the ph thing has been driving me nuts! I do water chemisty for a living and cant figure this out...after adding nutes the ph goes to 7.2 and i lower it to 5.9 before filling the res during water changes. The pool ph minus i use should do the job, but i'll try some gh products. I just dont understand...

Neither do I. Most nutes have buffers in the that lower ph. My tank usually drop at least a point after I add the nutes. VV

no light and low rez temps hmmm. well all i can think of is to check roots for rot, make sure to add your nutes first and check the ph after. some times the nutes will cause the ph to change a little once they get mixed in with the water better and once your pump cycles a few times. i would clean everything and run some clearex thru it all for a little bit and get some gh stuff.

Sorry to tell you, I've not been posting because I was raided by the pigs and jailed for my legal, medical grow op. They wiped me out and I'm struggling just to live. My sentencing was Tuesday, and now I'm a felon, so I haven't been very enthusiastic about answering growing questions. Hopefully I'll get back into it soon. Please bear with me, and many thanks to the community for helping.
