PPM and PH Rising

[Chubstrr]

I bet your light is pretty strong. It looks like you could raise it an inch or two.
Do you have enough fresh air coming in to the tent?

I am using a Spider-Farmer SF1000 and an SF2000 in a 4x2 tent. Consider them raised. I think I have enough fresh air coming in. I have a fan positioned at an opening to suck air into the tent and the exhaust fan blows clean air out. I have 4 fans inside blowing air around and I open the tent multiple times a day to allow fresh air to get into the room the tent is located in.

What strain is it?

I don’t run hydro fully. But I do run coco, and I push them pretty hard.

I haven’t run 3BOG, but I’m running a Mephisto strawberry nuggets right now. I had a similar issue. Only plant in my grow with an issue. I thought I was pushing it too hard, and was causing maybe a magnesium lockout. Then, I snapped and realized that when they were in my 4x2, they were way too close to the lights. They’ve been fine since I moved to my 4x4 and actually are doing very well. Healthy.

Dunno if that’s your issue. But @MikaelAndréasSöderberg may be onto something.

How far away are your lights now and are you using LED's? Hopefully it's as simple as raising the lights. Starting to wonder if having both the SF-1000 and SF-2000 in there is too much light. The total power draw between both is 300w. Not sure if that is too much for a 4x2 or not.

I’ve got my lights at around 12” NOW at around 1000 PPFD. But mine is 2-3 weeks away from being done. I always drop my lights a little lower towards the end to get more penetration to some of the lower buds.

But when it was in my 4x2 it got very close to my lights in veg. Around 10-12” I have a gorilla shorty for my veg tent, and lost track of how tall she was getting.

I run 320 watts in my 4x2 for veg. LED. It may not be the issue. But my Mephisto is fine below the top couple sets of leaves. Keep an eye and see if it progresses.

Okay I have pumped out around 8 gallons and pumped in 10 gallons of RO water that had 0 PPM going in.

Below are the following adjustments:

- Pumped out about 10 gallons of nutes from the res/mediums and filled with fresh 0 PPM RO Water.
- Added 2ml/Gallon of Hydroguard (40ml total)
- 1 Additional Airstone Installed in each medium bucket (not the res). Total of 2 stones per bucket now.
- Lights have been raised a few inches. Now sitting at about 16-17 inches above tallest cola's

New Readings:
PPM x700 scale: 710 PPM
EC: 1.0
PH: 5.8
Water Temp: 66 °F

Previous readings:
PPM x700 scale: 1260
EC: 1.8
PH: 5.8
Water Temp: 67 °F

These bitches are so damn spoiled I tell ya

9 hours later and PPM is now at 720 and PH has dropped to 5.5

PPM continues to rise and PH continues to fall. I didn't mark the water level after I removed some nute water and added fresh RO water but I did today. Today the water level appears to not have moved.
PPM: 770
PH: 5.4

So if PPM is rising and PH is falling and water level is staying the same does that mean I should add more fresh water to lower the PPM or add more nutrient water to increase the PPM?

Yes.

 

[Chubstrr]

Yes.

Which one? Sorry I may of been editing it when you replied.
