Yeh, i wouldnt go any higher tho until they start asking for it. Read what the plants want by the readings from your res. Once he EC starts to drop in the res, up your nuits abit. Visa versa if your giving them too much.

Hello mate,
Not too sure you've been given the right advice there !

I never take into consideration the waters natural E/C, And i have never needed to go over E/C 2.0 ever.

If you're on week 2 flowering i would start at 1.2....The following day or so your plants will tell you how close you are...Meaning if your E/C drops to say 1.0,Your E/C should have been 1.4...But if it remains at 1.2 your plants are taking equal amounts of nutes and water indicating correct E/C.


Sorry but i know if i gave my plants an E/C of 2.0 at week 2 i'd have problems......My current grow is at the end of week 3 with E/C of 1.4 and if anything they are showing mild over-nuting with some tips of leaves turning under....Like rams horns.

I think more opinions are needed.

im using vitalink grow a and b,
just added 30ml of each to a 20l tank (recomended amount) now i have an ec of 1.37,was going to let this settle overnight.

Well you should do otherwise you'll get a false reading. If you used a RO filter fair enough but everyones background ec differs. Why wouldnt you take it into consideration?

I've just told him that....

Well i beg to differ...
My background ec is 0.6, my tanks are running at 1.8 on the truncheon....so the actual nuit content is 1.2, they are near 3 weeks in.
Sounds like your having probs. whereas mine are lush as the preverbial.... :yahoo:

maybe theres a bit of confusion Hydro on post 3
as in the OP asks he should not include the base level EC "do i not include the water EC"?

you replied "yes"

ie do not include the water ec(i know the math is there but...)

sometimes, more than one word answers help others a bit more

Which ever way you go mate...... Keep in mind its easier to add nutes than to remove them.

Would have ec at 0.6 week one, 1.0 ec at week 2 and 1.2 for week 3-4 or for however long I want to leave it before flowering, if slight colouring up it slightly, if tips are burnt on all leaves lower it slightly.

So base water is 0.8, week two would be around 1.8 ec to give to an ec of around 1.0, week three would set it on EC 2.0 which is basically 1.2ec.

Although each to there own.

thanks peeps,
i think i was slightly under feeding the first week or so.as i included this base level of ec,so realy was only giving the plants 0.1- 0.2 of nutes,
now i have upd the ec to 1.8 the plants realy have gone wild these last few days and ec is staying around 1.75 ,so i assume they are happy at this level,
but like others have said,i will just keep a eye on the readings and hopfully they will start telling me what they want.
many thanks :wink:
