Fast Forward Day 2 GDP

This is a reconstructed thread with all my photos moved here to GC. So this is a GDP grow, with some BF Blue Cheese, and DS Cotton Candy mixed in. And and....one bag seed.

 

My 4x8x8 tent.

 

Now a problem.....

 

The silly bag seed is the big one at the back left. It is 30 days old now and still this small.

 

The best I can figure is this is day 17 from sprouting.

 

So for Speed....

Nutes:

AN Sensi Grow A&B pH Perfect
AN Voodoo Juice
AN B52
AN Organic B1

I am mixing these 75% of recommended levels. pH is 5.4 after mix and then about 6.1 the next day I have been following advice from AN.

My system is RDWC, with reservoir outside the tent, chilled to a temp of 68F.

My inside the tent temps range from 70 to 78 F. My humidity is 45-60%, but mostly around 55%.

My lights are 2x 600W Lumatek with HPS bulbs. Was using metal halide until I moved into the tent.

I have mucho negative pressure on the tent, those are both CAN fans, one is HO and one on carbon filter is regular 8". I have lots of air conditioned air being sucked into the tent. I exhaust everything outside in attic.

The chiller sits outside the tent by reservoir.

I check pH and PPM with HM handheld meters and a continuous wall mount unit.

PPM is currently 910 or so.

Nutes changed every 7 days.

RO water used for nute mix.

Anything else you can think of to help solve the problem?

 

I am using BudSlingers Recirculating bubble bucket system that I built from his excellent tutorial. Just modified a little.

 

Maybe I nute burned them during the days before move to the tent.... And now I am seeing the results of that burn. I am not sure. See the last picture in post #2.

 

I selected "Sensi Grow" in the drop down box...that is the vegetative Sensi two part chart. Is that the wrong one? The GDP is 17 days old now, I am calling this week two of veg.

The chart I selected only has the products I am using. I actually have the entire Grand Master line, but most of it is for flowering as I understand.

The tent is 4x8x8 and i have two 600's , I don't see how I can fit more lights in.

I have the vent open on the tent, that is where my negative pressure sucks from. The lights are sucking outside air from the room. The carbon filter is sucking from inside tent.

Thanks. I will stay on top of the pH and keep it 5.8.

 

Speed...

Here is my exhaust to the attic



The carbon scrubber and light cooling exhausts through this Tee



This is air condition air sucked in across the lights only



This is my fresh air intake, being sucked by carbon scrubber and providing negative pressure to room.

 

Here are my ballasts wired to a 240V dryer outlet and heavy duty 240V timer. My waste disposal and water source are just behind the edge of the tent. And the RO system.



And here is the chiller and reservoir for 4 bubble buckets.

 

Ok then next week I am going to full strength since that will be the third week of Veg. I did adjust pH just earlier to 5.8. Hope that is ok with you.

The schedule for flowering with grand master has about 15 ingredients. Going to be fun...

 

Jake,

Thanks for posting. The tubing I have came from McMasterCarr. But they advertise it as PVC tubing. I don't know if PVC is reactive at these pHs or not. But damn, what an idea. I wonder if I could duplicate the issue in a small test.
