Thanks, these are the last two ILGM Master Kush Ultra in their line. Had a vent fan for exhaust come off in my Durban Poison tent and cook it, that’s why no pic’s of it. 1 or 2 more weeks it will be normal.


I have a hard time "Because I don’t log PPM/PH :see_no_evil: :hear_no_evil: :speak_no_evil: " on keeping the PPM down this late in flower so it doesn’t get PH drops. Plants shouldn’t be yellowing that much, PH lockout

I have never done Deepwater culture so I cannot speak from experience but from what I have seen looking around bigger is better with those 5 gallon buckets you need to constantly pay attention to Ppm a little and pH a lot because you don’t have a very large volume of nutrient solution so when it evaporates you have huge swings in a short time because you’re small volume of water changes concentration
 To put it simply if you have a 5 gallon bucket and it evaporate 10% of the water a day if you switched to a 20 gallon tote you would only be losing 2.5% volume a day so you can go longer without having big swings in your numbers
 I’m growing in Rockwool on a flood table doing top water I’m just finishing 
up my next run I’m switching from a 20 to a 38 gallon tote so I don’t have to check it but every four days.

Those plant would drink the bucket dry everyday. One res per tent with @12gal±


That’s those same two clones when they were put there

My PPM to keep the plants in the last week of flower before flush is PPM 200-250 and only PPM 300-400 in full flower. Having a stable PH tells you where your PPM Should be. PH drifts down meaning plant taking-up more water than nutes. PH drifts up PPM is to low and plant is taking-up more nutes than water.
PPM right PH will be right too.

That’s interesting
 The rep from the nutrient company that I’m using was trying to explain that to me with how to use these nutrients towards the end of flowering but there’s a big difference in numbers most of my flower Time I am running my numbers about 1020 PPM and then dropping to half that last week before flush

I normally start off with 2 gal full strength then add it to about 10 gals of water on the reservoir until I get the PPM I want keep about 1/4 gal just incase the plant wants the PPM higher so I can add the next day.
PPM 600 would burn the tips on my plants

Looks like ten more day until I flower them, wonder if the lights will be far enough away from plants.

If you put a net in there about 6 or 8 inches below where the tops are now and bend them over underneath they will grow through the net and keep going meanwhile you just gained 6 or 8 inches
 You could also just flip the flower now if you’re worried about height
 How much more room do you have to go up?

I think I’m a little confused here I see pictures of a tent with short plants in a net and I see A tent with a blurpul lite and no net
 Do you have two tents one veg and one flower?..

2 flower tents(4x4 one plant, two plant’s 4x8) and a 32"x32" with no vent " doors always open" that sits behind my desk for clones and seedlings. Clones are about 7+_ weeks old , they look bigger than the ILMG Master Kush Ultra I’ve been cloning for the last year.

Just like a hard defoliation only with heat not shears


Doesn’t look that bad for a plant I wasn’t sure would make it

ILGM Master Kush hard like an apple.

I was going to ask you about the water chiller is that the white thing that’s by your tanks with the hose thats going in and out of it?..

Wasn’t so hot when there was only one tent in the room. I lucked out and got the 1/10hp chiller for $100 new. I only use it 3-4 months a year, most of the time its to cold.

Does the chiller produce a lot of heat while it’s cooling the water?

I feel if the root’s are 68F the top of the plant can handle the 90’s, just like outside.
