That sounds about perfect. Any root shots?

I apologize for not doing this yesterday but I broke a phone and lost some pics. I will have to take some for you a little bit later today for you guys. They started to get a little funky above the waterline but behind the dead roots started coming the thicker ones. The roots dying came about the same time the spots started and from what I understand it seemed to coincide perfectly with a cal mag def. I added some more calmag and it did not seem to help much after a few days so we did a res change yesterday with fresh nutes at 1/4 strength and "calimagic" at 1.5 ml per gallon. Does anyone have any experience with this because I was told to use 5ml per gallon and it brought it up to about 350 ppm or so of just calmag. This seemed really excessive from what I have been told about running light nutes in dwc, escpecially considering my total ppm has just reached 400. Am I just majorly underfeeding these guys? I have no idea what I am doing essentially. If the nut change doesnt help I dont really know what to do. Any input? I really just want to leave this thing the heck alone for a couple days but I know somethin isnt right.

I think you made the right choice by doing a rez change and reducing nutes. Personally while in veg, I do super light feeding even less than 1/4 strength (for the first week). When the plants look like they can handle more I do an increase. I veg a lot longer than most so I actually try to feed them less while I am waiting for the flower room to finish up. If they are green and happy I figure there is no reason to increase the nutes until they look like they are starting to starve, turning a little more pale, etc. Hope that makes sense and or helps.

Again I am in aero though so not sure if this translates over or not. Recirculating I don't think you need as high of a concentration since they are constantly being fed.

Maybe @DrFrankenstien can chime in. I think he has a little experience with DWC.

They look like they are coming back nicely. They have fish bones on the bottom. I wonder why the upper section doesn't look as good?

My thoughts exactly... After the res change I saw some new roots developing in some areas around the pots yesterday, so I added some tea to see if it helps or hurts it. I am just trying to pinpoint what is/was killing my roots because I think that is the root(intentional pun) of my problem with some of the spotting and cal def syptoms. After today I should be at about 1/4 strength nutes and additives, then I just want to leave it the hell alone. Know what I mean?!

nice start
carbon filter/fan looks a bit small though for when they flower .. ok for now

how much light are you going to flower them with?
you have enough plants there to fill all that rooms floor space and get a nice yield
i was wondering if it will be ok smell and heat wise with a few lights in there

peace

Good questions! You may be missing the other filter that comes off the T on the fan. It sits under the shelf, behind the chiller and the other hot stuff in order to get the heat out. The only reason I put the little filter on the top is because 1) I had it 2) the light needed to be ventilated and that room stinks. So basically there are 2 filters. I am setting up a room for Coco right now and that vent also goes through the 1000Watts in the other room. I will post some pics later the room is off limits because of preventive bug bombing. We should have some clones coming tonight. I will be putting up 2 1000W in the room you see as well, but I am still vegging them and then those lights you see will be put into the new veg room. In the end, there will be one veg and two flower rooms. What you see is the beginning of what I hope to be a 30-45 day perpetual harvest with 2 3000-4000w rooms. Ya dig?

PS
The temps with 2 1000w was 84 in the other room without a fan circulating air. I will be running some tests tonight to make sure I am hitting the numbers I want. Hoping to avoid having to hook up an AC right at the ass end of summer weather :( We do what we need to though.

I didn't mean to jump down your throat. It's like this. I'm the type of person who will talk from my experiences, not from talking about it. A lot of people on here only know people who have grown but never themselves. I've killed a lot of plants, even one 2 weeks out. Every environment is different and different strains can handle different environments. We live and we learn, hopefully.

I by no means think I know it all and I've read several things about light being bad for the stomata (under side of leaf) especially in the first month of life and voidobject belives this as well http://rollitup.org/t/how-to-dwc.468072/ its a sticky under dwc\bubbleponics

very true king every situation And grow is different and no problem I know there's alot of misinformation but I try to give advise on stuff I have at least put some time in researching or have first hand experience on

Who stole my avatar and started giving RDWC advice?!

Number one, lose the 'ppm' thing; there are several different ppm scales and unless you know which is which it will Fuck you up bad. The nute companies themselves don't even agree on which to use, so stick with EC, aka electrical conductivity. It isn't perfect either, but it is universal.

Second, I run about EC 1.2 in veg and ramp up through bloom to 1.7 at peak, then right back down to 1.2 at finish.

I like to let pH swing upwards slowly. If it swings up fast, the solution is weak. If it drops, too strong. For veg in RDWC 5.4 up to 5.8 works best. Bloom runs 5.5-5.8 early, then creeping up to 6.0 in peak and thereafter.

I like my temps anywhere between 62 and 68f. Seventy is okay for short periods but needs to drop to maintain the balance of microbial power in favor of the aerobic beneficials. Warmer IS better for metabolism, so allowing daytime temps to creep up and then cooling overnight to at least 68 or 66f works very well for me.

If it matters, I use hydroton and I like to keep my water just touching the netpot in late veg, until they drop roots. Then half to an inch clearance is the goal. Drop it low at harvest time to encourage a sweet finish!

Thank you soooo much for this. I have pretty much drawn this as my own conclusion but from taking parts of advice from a bunch of different sources. Its just nice to see it in one place :)

We seem to have contracted some sort of virus and as some plants are pushing through it much better than others, we still have a global issue in the system. We have taken some advice from a good source and have put some aspirin in there, along with some more silica. We are just gonna have to charge through this and see what we get. It could be from the seeds, who knows. Any experience with this kinda thing?

Forget putting silica in the water, all it does is screw up your pH. Use 15 ml/gal of liquid silica to foliar spray for powdery mildew and general health.

Aspirin didn't do anything for me. Brew up a batch of tea and crown feed, they love that. Keep your temps in the mid sixties.

To get the lines out, turn off the light. That's what I do. Only takes about 5 mins. to get all the shots I need. Then turn it back on.

lower the t5 a few inches. i have mine like 2 inches from tallest ones. t5s are great for veg. keep up good work

Here is an update! I just got the Coco room set up and I have no idea how to take pics under HPS without those lines. What am I not doin here? Took some clones to double check the sex.
