Be careful of ph fluctuations if you have any, it might be causing droopy leaves (or not, still researching to find out what's been happening in mine)
the exact same thing is happening in mine
Mine is still fluctuating up to 7.0 from around 5.8-6.0 ish. When I see that it is up I adjust it back down is this a bad idea? Changed the reservoir out 2 days ago and set the Ph'd water to around 6.0. I checked it last night and it was back to 7.0 again so I adjusted it back down. Is this much fluctuation detrimental?

no it is completely normal for it to fluctuate like that. every waterfarm i have seen does it. i just lower the ph of my add back and that usually stabilizes it for a day then it climbs back up. i think the droopy leaves are from a different problem. dont quote me on any of that though as im still a massive noob

Actually a bit of fluctuation is something good; different nutrients are available at different pH levels so having your pH fluctuate "a bit" makes more nutrients available all together hence a more healthy and nutrient rich plant. Of course this is only a bit of fluctuations, not from 4 to 7 in one day.

About the droopy leaves; usually a sign of over-watering although with a Waterfarm the only way that would happen is if you turned your pumps off. The WF pumps must always be running 24/7. Another thing could be that your looking at them right before they go to their night cycle. Plants tend to get accustomed to their schedule and after a while they know when the lights will be going off and sort of calm down and drop their leaves just how someone get's tired after a certain time of night they start to get drowsy and sleepy. The opposite happens when they are just about to enter their light cycle; it's leaves shoot up into the air and spread getting ready to receive the light.

Anyway hope it helps friend. Keep us posted. :)

Sounds good I'm a total newb too so I'm learning a little bit every day haha.

Sounds good, my plant has started its first day of the 13/11 light cycle and so far the leaves have been very perky. I will continue to adjust the PH as I see it rise and I will change out the water every week or more to ensure that it stays fairly fresh. I'm also going to use the add back technique to keep things simple. Thanks as always for the input! I might post some fresh pictures tonight to show the progress of the secondary leaves.

Cheers

Sounds like you have a good handle on things friend. Yeah I also changed the reservoir about once or twice a week during veg and topping it off with pH'ed water only in between to keep the nutrients level. You don't want to add back water that has nutrients because (IMO) it creates a disbalance in the nutrients; let's say your plant is uptaking more N (nitrogen) than P or K (normal during veg) and you keep adding P and K while your topping off with nutrient water, this will cause the P and K to progressively accumulate and eventually cause nutrient burn because the plant is primarily uptaking N. What I do is if my ppm reading is at or below the initial measurement of the last reservoir change then I top with nutrient water (at the same ppm as the last reservoir change), if the reading is above the initial measurement of the last reservoir change then I top off with only pH'ed water (with no nutrients). Hope it helps friend, hope to see some pics soon. :)

Good thing that I know your ph is not causing you problems. I think mine's due to overwatering then. I made me a new ring with smaller holes and not so close to each other like the other one, I'll see how that goes.

That makes perfect sense I totally agree. I'm glad the ph is only fluctuating 1.0 or so. I can't wait to start introducing nutes to this girl.

I'm curious if this new ring will work better for you. I noticed the other day that the waterfarm drip ring doesn't have very many holes. I don't know if that's a good or bad thing, but I'm curious to see if you notice any beneficial results from your new drip ring.

And also, here is a small photo update to track progress:

I had some issues with both my timers and my lighting setup yesterday. There were random periods of light and dark at all the wrong times and my airpump even went off for at least an hour.... I don't know if it's a problem because it's so young or what. It still looks good and I now have it running on 250watts of metal halide at about 3.25 ft. I think I will start to introduce a low nutrient dose later this week. Let me know what you think?

I don't think that a minor setback like that will damage the plant. Obviously not good to happen but if it's a one off it's quite ok (I think) :)
You can lower the light, I'm running a 400 and it's at about 1 foot away from the plant, temperature's not an issue (at max is at 27C about 80F). About nutes... I can't make a call there. Maybe a slight dose and see how she'll react?

My new ring btw worked like a charm ;)

depends on if your running a cool tube etc. im running a 600w with a air cooled hood and i got that bad boy sitting at about 9" from the top of my plant and she is loving it

Okay time for an update. I have turned the MH up to 400w's now. Still keeping it up high for now because I want to ease into it. I've noticed lots of salts building up on my hydroton and also it keeps getting very dry up to 1" deep or more. So I went ahead and covered it with some aluminum foil as you can see. My plant seems to be growing slowly, but surely. I have noticed that my leaves are a bit pale and yellowish. I really want to focus on having a healthy plant so I'm wondering if this means that it is looking for nutrients? Last night I changed out half of the res water with fresh ph'd tap water and added a small amount of micro and bloom nutes. My stats as of right now are:

Temp: 72-80 degrees.
Humidity: 50-60%
PH: about 6.2
PPM: 188

Any input would be great.

I also forgot to mention that there are small brown spots appearing on the tips of the cotyledon leaves. You might notice them in the first picture if you look closely. What do you think?

Cheers

Your plant looks great. Don't worry about the cotyledons, the spot could be from the shell, might have taken a bit longer to discard it, but anyway we're not talking about real leaves ;)

i agree with bluez. your plants look good at this stage the important thing is to not freak out over every little spot on them.

Sounds good. Does it look safe enough to start adding nutes in at say 1/4 strength or should I wait a little bit longer?

hey mdhas u said u want to focus on keeping a healthy plant then the last thing you want to do is burn them with nutes. i would suggest following scottyballs system, if the ppms in your res are going down between changes then its time to up them if they are staying the same then your sweet and if they go up they are too high. so i see your already running 188ppm so if you check your res and its still at about 188ppm roughly then stay where you are but if they have dropped to like 100ppm maybe its time to go a little higher. your plant will tell u what she wants. im just learning this myself but its working. if your worried about her looking a little pale i found when i was using flora nova bloom mine were a little pale, as soon as i switched to grow they greened right up. i reckon if shes a little pale she probably wants more nitrogen so adding a little flora gro would probably help. if it was me i would still not go over 200ppm and just see how she likes it.

Checked the reservoir tonight and PPM dropped from 188 - 181 not very significant. I'm going to leave it for now. Do you keep your water level at the base of the upper chamber or at the marked white line on the tube?
 

forgetiwashere

i usually aim for the white line which i believe would be pretty close to the bottom of the top pot anyway then let it drop a little below. your pump will work better if you keep it full but u will get better aeration if its a little low as all the drops falling from the top pot into the bottom pot will help aerate the water.

White line, don't go above it, I think maybe 1/2" above is the grow chamber. In early veg I don't add back until it's time to change out water, I feel as if it's a waste to continue to add that much water to the res when a little veg plant won't drink anything close to 2 gallons in a week. For flowering especially deep into flower I let it drink a gallon then add back a gallon. I do that for 3-7 days depending then change out res with fresh nutes. So many waterfarm scrogs! I don't think I can sub them all.. lol

Subbed for this one too.

p.s. Never forget, less is more with nutes. Don't go nute crazy.
