Yes that means stop nutrients and flushing is when you pour plain water into the container....a lot of water. Usually 3 times the volume of the container. A ph meter tells you the ph of the nutrient solution. A ppm/tds meter tells the Total Disolved Solids...how do you know your ph?...do you have a test kit

i have a ph meter i bought from growell in fulham london , just dip it in the water and tells me the ph of the water i usually make sure that the ph is 5.9 after i have mixd in the nutes to the water,i dont have any ppm/tds or anythin like dat i have a manual ph kit and a digital ph meter(digital ph meter comes with a calibration solution ph 7 buffer).
Usually 3 times the volume of the container?
thnx mate, your makin alot of sense i will jus use normal tap water at ph 5.8 using da ph down solution(phosphoric acid) but for how long
when should i go back to using nutes?

Oh ok I missed that earlier that you had a ph meter. Yes 3 times the container...but since you've got the RW cubes 2-3 ltrs would be enough. I'd wait and see how they respond before trying to add nutes. I meant to ask what method you're growing too. I just assumed earlier that it was ebb n flow

ok im in vegitation stage at the moment i have 2 budboxes 1 for vegi and 1 for flowerin stage...below are pics of the vegitation budbox and my set up, its a bit difrent from wat i usually see, i managed 2 make it after watchin a perticular vid on youtube lol
pic1 - thats the budbox lights resorvoir and trays with RW (9 in total, 1 died)
pic2 - close up with the dripers i took em out 2 giv u a clear picture
pic3 - the 2 trays have holes with hose going down back into the resorvoir
pic4 - same again with close up

Nice set-up guru...very clean. Remember to keep it that way and you'll help avoid problems. I burnt my first seedlings too. The book I read said to fertilize once 2 or 3 leaf sets appeared, which I did...but I still burnt them. Now let me tell you about the rep. system. When you get good advice and want to thank someone....anyone....lol (I want to see what happens after I get one more.) you can give them a reputation point. Do it by clicking on the little scale symbol at the top right of the members post you wish to rep. I'll show you

Ok go to your My Rollitup buton...scroll all the way to the bottom and you'll see it

yh iv done it, so wat happend, hey by the way were are you from, im from west london...

Crap it didn't raise the point...I guess it takes 2 per point or something.....I'm still trying to figure it out myself if you couldn't allready tell. Did you see yours on your "homepage"? It just shows these little icons.
I'm in the states....I figured you were from the UK or somewhere in EU because of the meteric measurements. Where did you get your seeds from?

i forgot to ask you 1 more thing...how high from the top leaf should i have the lights.

should i keep it at 1 foot or 4-5inches?

thnx mate

Sorry it took a while I some things to take care of. Ok...I'll just answer in order. 3 Ltrs for all of them should be fine...just once...then continue with your normal watering regimen minus nutes and see how they respond.
Yup thats where the points come from....man I would love to go to amsterdam...sounds like you did it up right. And yeah diesel is some great stuff I hear...I've only had sour diesel, which was awesome.
When my plants are your's size I have my t5 flouros about 4 inches or so I guess and as they get bigger I let them grow closer to the lights...just make sure its not too hot for them.

by the way...this one still looks a little the same, i dont think it will make it...oh well...from 10 now down to 8, but i might just give it another week to see how she does.

Alright! glad they're recovering...yeah I'd give those 2 some more time. You'd be surprised what they can bounce back from.

Not to hijack your thread, but I bought my seeds from Nirvana and my AK-48s are curling once in a while as well. I can't figure out what straightens them out when they are acting right. My other seeds I bought from Nirvana, both the Pure Power Plants and the freebies aren't curling. That's what brought me here-- hope we get the right answer we're looking for. Sorry for hijacking-just having same problem with same seeds. Are all yours AK-48?) Dang I just saw this thread is 7 years old. Well, I may get some newer answers because I know it's not the nutes, I haven't given my any yet, they are only 3 weeks old, in good soil and ph'd water.
