Help please, possible humidity or nute deficiency

Was able to take the plants out into better light. Unfortunately my camera sucks, hopefully it's enough to identify the problem.

Info:
Trinity Superponics, not top feeding yet
Day 29 from seed, day 4 in veg
2 Vanilla Kush, my other 2 plants are not having a problem (Critical + & Cali Hash)
600 hps 18/6
79.9'
20%
5.9 ph
280 ppm
82.1' h20

I started misting the plants today with RO water. I'm working on raising the humidity. Got a humidifier this morning, did nothing except leak all over the chamber. Have glass dishes and bottles filled with water plus wet towels, hasn't raised it a tiny point since earlier. Went up 7% for a bit, then dropped down to 20% again. I'll be getting a better unit tomorrow.

The tips on the lower leaves just started to turn today. They went quick. The spots have been there for about 6 days. Only on the VK, only on the bottom 3 leaves for each VK.

For about 1.5 weeks before veg, the plants had brown slime and the rez was changed and treated with aquashield, senizym, and rapid start. I accidentally gave them 1.5 strength rapid start for about 1 week. When they switched to veg 4 days ago, I did less than 1/4 strength Technaflora Vegetative State formula, consisting of the below.

When I moved the plants to the veg chamber, I increased the amount to just under 1/4 strength (290 ppm). I prepped three 5 gallon bottle as if each were 1 gallon (making it less than 1/4 strength). The veg chamber rez holds about 17 gallons just under the net pots. My RO water is 18 ppm at start. After adding the 15 gallons mixed below, I filled an additional 2 gallons of the same mix, but about half strength of below, the ppm was 145. Basically, my nutes are at about 1/6th, or less, of the Technaflora Veg State formula (Technaflora came with the Supercloset Trinity)

For each 5 gallon bottle:

BC Boost - 3 tsp

BC Grow - 1.5 tsp

Thrive Alive
B-1 Red - 1/2 tsp

MagiCal - 1/2 tsp

SugarDaddy- 2 tsp

Aqua Shield - 1 Tblsn

Sensizym - 2 tsp

Rapid Start - 1/2 tsp


The spots were on the leaves before moving to veg. They have not gotten worse. The leaves yellowing in between the veins was barely visible upon switching to veg, wasn't sure if I was seeing it at all, looked more like a very slightly mottled appearance on 1 leaf . The tips on the sides of the leaves just happened today. The very tip of 2 leaves was slightly brown for a while. I'm talking the size of a dot of a fine tipped marker. They have worsened and curled today.

For 3 weeks my ph was higher than I thought. I had hoped that the nute deficiency that was beginning to show before moving to veg would be addressed with the nutes being added. I don't think it is nute burn. Was hoping that it had something to do with the lack of humidity.

Think I covered everything.

Thank you for any help or guidance.

honestly, it looks like you may have sprinkled some nutes, or water, or beer.... something wet is all I mean, and your light burnt holes in your leaves.

Are you saying your water (h2o) is 82.1 degrees????

You sure give your little bitty plant a lot of different stuff. I am a strong believer in KISS. I have done the Advanced Nutrient regime with 15 different bottles and a few other brands. I have found that a simple A & B Nutrient with neptunes seaweed plant food gives me good growth and large plump buds. If I was you I will chill out on throwing everything under the sun at you plants. I swear bye Cyco Brand Nutrients. At least with my water, it is mix and feed. Everytime. None of these huge PH adjustments. And it keeps my PH within my medium on a nice even keel.

Just my opinion though.

Thanks for all the input. Yeah, I'll admit, it's more than I thought I would have to give them, but the last 3 things on the list were a must because of the brown slime, I was told to continue them to keep the slime away. It's off my roots, but it is still through my rockwool, so I thought it best to listen to that advice. The other stuff is what I was told was the "complete" nutes for veg. It's Technaflora's Veg mix. First grow, what the hell do I know, lol. I follow directions. Live and learn, right? I wanted to do organic, but I'm glad to be using what they sent me for now. I have a feeling organic won't be until I get a hang of this way.

Yes, my water in the veg rez is 82.1, it went up about 6-8' when I switched from cloner (6 gallons) to the veg chamber (17). I thought it would cool down given that there was more water, but the circulation pump throws off a shitload of heat. I'm hoping that when I begin to top feed that will cool the water. Odd thing is that my temp in the cloner rez also increased a couple of degrees. Nothing else has changed at all. The ambient temp has actually been a degree or two cooler.

The humidity in the cloner was usually around 30ish, that hasn't been above 27% since the change. The humidity in the veg only went up to 27% for a short period of time today. I've got shitloads of water in there under the lights. I don't get it, unless all my meters are suddenly off. I'll probably reset everything tomorrow just to check.

Not sure how nutes could have gotten on them, I just began misting them today. Other than that, I can't remember an opportunity when that would have happened.

So, no shot of it being lack of humidity?

yea this happens if you foliar feed, causes the bleaching of the leaves. white spots usually isnt a deficiency. its a burn.

Make sure when you do foliar feed, you turn the lights off til they dry, or do it right as the lights come on. Dont do it right as the lights go off, as that leaves them susceptible to rot/mold/fungus
Another way to boost humidity is a container/bucket/cooking pan/something preferably large and shallow filled with water under the lights.
if the temp of the grow area is 82 degrees, the h2o will evaporate easily... perhaps your losing it all, thru a AC vent, or under the door, or something, you got an exhaust fan or something removing the air? its good to have air circulation, but in the room, not in and out of the room... get what im saying?

when i did hydro back in DC my humidity was high, now im in a tropical climate and im fighting to keep it down lol.

Rez temps of 82.1 degrees is way to high. You are starveing your plant for oxygen. You need to have that temp down around 68 degrees. And following the direction of some of these corperations is just crazy to me. These Corps. are all about profits, and if they can talk people into useing a more broad range of nutrients at a larger amount means more money in their coffers.

How the hell do I get my water temps down? Good thing is that the roots aren't down yet in the veg chamber, so the water that bubbles up is much cooler.

What's the humidity supposed to be in the cloner chamber? 27% out of the dome, imagine the dome is higher.

Damn, every day it's some new expense, and I will eventually have 3 rez's going at the same time. Yikes. So now I need a humidifier and something to cool 2 rezs.

Have 1 VK that is looking pretty wilty on those bottom leaves today. Hydro store first stop.

I haven't foliar fed yet. Just started spraying with distilled water yesterday to keep the humidity up. When I mist with plain water I need to turn the lights off? Well that might explain today's wilting of the lower leaves.

Knew this would be challenging, but it's harder than I thought. I am leaving in a week for 4 days, hope I get it worked out by then.

You can cool you rez by putting a 2 liter bottle of frozen water in there. Get three of them, so you can always have two of them in the freezer.

i am throwing something up in the air here ??? what about bags of ice in your res on all 4 corners ?? would this work in cooling your res ??? i am a soil grower so not sure if it would

I often get spots like that when I am careless and leave water droplets on the leaves. But, that's not the only problem that can cause these symptoms. One pic shows the whole end of the leaf turning crispy. Not sure what that is.

The thing to watch is, is it spreading?

well the reservoir your using for the plant water, and the reservoir your using to up the humidity should be different. the plant reservoir (where the roots are chilling) should get 0 light, or youll promote algae growth, and raise the temp.

Thanks all. Was told it was probably rust and to spray w/fungicide. Also given beneficial bacteria. I'm not convinced it's rust, the pics I've seen look a bit different. I don't want to add bennies until I return from vacay, just in case it gets out of control before or while I'm gone.

Now the older, lower leaves that had the spots have turned pale yellow and wilted. I sprayed fungicide while dark. Got another humidifier, so we'll see how that goes.

I'm convinced that I have a nute deficiency. On some of my newer growth, I can faintly make out from the tips to middle of the leaves getting paler, slightly yellow, but the veins are green. Possibilities as follows:

Potassium
Magnesium
Calcium
Zinc

The spots could indicate calcium. The yellowing and necrosis could be any of them. Reading up on more today. Was excited to hear Ed Rosenthal is releasing a new book, with pics, about MMJ diseases and pests. Comes out Dec 11, 2011

Been doing frozen bottles in my rez, dropped it to the 80ish. I didn't think it would be this difficult. Also started to top feed. Had originally been told not to until the roots and water level dropped. Hydro guy said that may be part of my problem. By the time I heard this, my roots had dropped anyway, so was changing to top feed.

I'll be posting new pics tomorrow.

These claims are preposterous.

Your problem is a micronute. I would say iron, possibly magnesium. Could be burn or deficiency.. similar symptoms. The problem is that your Ph is either too high or low, not allowing micronute access to your babies' roots. What is your ph at right now?? Take your PPM into acount as well.. I trust you have the tools necessary to monitor.

Suggestion:
1) Your babies look small still.. be gentle on them. Run at a ppm of about 500-600.
2)PH - Science says 5.8 - 6.8. I used to run at 6.2 - 6.4, and I have had no problems.

Possibles:
1) Nuke them with oxygen... perhaps 82 is a bit high.. long as you got enough stones in that bad boy, roots will be fine.
2) If you're using tapwater, check out the PH in it... if need be I would recommend throwing some of GH's micro in with it, just to nullify the effects of your chlorine and chloromine and all the other bad shit that your water company wont tell you about.

Good luck, Sir! I had the same problem my first hydro grow... ended up being nute burn. Experience has taught me, nature enjoys optimum conditions. Ups your chances of having girls.

Hi. Thanks for the input. I'm a bit confused by it as you are telling me vastly different numbers than what I've been hearing & reading.

I had been leaning more towards magnesium & calcium, and since I use magiCal I figured it would take care of my issue. Just not sure of how much to put in.

Today's stats:

Day 30 from seed
2 Vanilla Kush (no problems with my Cali Hash or Critical +)
RO (ppm 1
Superponics (hydro & aero combo)
300 hps 18/6

84'
30%
ph 5.9
Ppm 270
H2o 81'

I have been told to keep the ppm under 325.
Thought ph on hydro was 5.3-6.3?

When you say these claims a preposterous, could you please specify which ones? Thanks.

Yes, total newbie. First grow. I am always appreciative and thankful for input.

The yellow spots aren't spreading, but the yellow edges came and spread quick, now most of the yellow spotted leaves are fully pale yellow and wilted. They look like they should be cut off.

Can't take pics until kiddo bedtime. First thing Monday.
