2-27-04, Day #15 of Flowering:
Cab Temp 75f, RH 58%, Nute Temp 73f, PPM 1500, Ph 5.8.
The plants drank over a gallon of water each since yesterday so the ppm is now up to 1500 with a ph of 5.5.
The plants don’t seem to mind the higher ppm, so I’m going to leave it there. But I will get the ph back up.
I added 1 gal top up solution to each bubbler today.
This is what I added to the 2 gallons of top up solution.
5 ml per gal Micro
2.5 ml per gal Grow
10 ml per gal Bloom
2 ml per gal Silicone
After adding this to the bubblers the ph was 5.8 & the ppm was 1500.
The plants are still stretching & are now 31” tall.
That leaves me about 5 more inches to move the light up before I run out of room.
2-28-04, Day #16 of Flowering:
Cab Temp 75f, RH 58%, Nute Temp 72f, PPM 1500, Ph 5.7.
Not much going on today but stretching, 2 more inches since yesterday. They’re now 33” tall. I hope the stretch stops soon.
There’s no sign of nute burn from the higher ppm so I’m going to leave it at 1500 until the next res. change.
2-29-04, Day #17 of Flowering:
Cab Temp 75f, RH 58%, Nute Temp 72f, PPM 1500, Ph 5.8.
The plants drank about ½ gal of water last night, which brought the ppm up to 1600.
I added ½ gal of plain water ph’d to 5.8 to both bubblers bringing the ppm back down to 1500.
The plants grew another inch since yesterday. So it looks like I’m going to be doing some late training.
I tied the tallest tops down enough to get them even with the other tops, which gave me another 4” of space to move the light up.
Hopefully that’s enough because I’m not so sure I’ll be able to pull them any lower.
The two tallest branches folded in half while I was pulling them down leaving a crease where it folded.
I’ve got them supported with wires so I don’t think it will cause any lasting damage. It might even make the stems stronger.
Here are a few pics of before & after training & a couple of flowers starting to form.

3-1-04, Day #18 of Flowering:
Cab Temp 79f, RH 50%, Nute Temp 72f, PPM 1500, Ph 5.8.
Same drill as yesterday.
The plants drank about ½ gal of water, which brought the ppm up to 1600.
I added ½ gal of plain water ph’d to 5.8 to both bubblers bringing the ppm back down to 1500.
I had to tie several of the tops down again today to keep them even with the rest of the canopy.
The highest top in the canopy is now 30” tall. They were 34” yesterday & would have been 35” by today.
So basically I gained 5” by getting the canopy even again.
Here’s an interesting side note. The two branches that folded in half yesterday, were the two that grew the most. Go figure.
Now that the plants are getting a lot of pistils, I decided to lower the humidity.
I’ll keep it between 40% & 50% for the next 2 to 3 weeks. Once the buds start to get some density, I’ll let the humidity drop into the 30s.
Keeping the humidity lower towards the end of flowering should stop any mold from growing on the buds.
If the buds get mold on them, they aren’t healthy to smoke. And that would mean I just wasted 3 to 4 months worth of time & effort.
Keeping the humidity lower makes the temp in my cab go up. By the end of flowering it will probably be in the mid to high 80s.
From what I’ve read, the plants will produce more trichomes as a form of protection from the higher temp & lower humidity.
So bring on the trichomes baby.
3-2-04, Day #19 of Flowering:
Cab Temp 82f, RH 52%, Nute Temp 72f, PPM 1610, Ph 5.7.
I changed the solution in the bubblers today.
Here’s what I added to 10 gallons of water to make the new solution.
8 ml per gal Micro
3 ml per gal Grow
16 ml per gal Bloom
3 ml per gal Ph Down
This made the ppm of the new solution 1600 with a ph of 5.5.
After adding this to the bubblers, the ppm was 1610 with a ph of 5.7.
I’ll check the ph every couple of hours, as I’m sure the ph will drift up dramatically, like it always does after a solution change.
The plants grew less than an inch since yesterday, so hopefully the flowering stretch is about over. I sure hope so anyway. I’ve only got 5” left for the lights to move up. The canopy is staying nice & even too. So no retying was needed today.
Here are a few pics from Day #19 of Flowering:

3-3-04, Day #20 of Flowering:
Cab Temp 81f, RH 52%, Nute Temp 72f, PPM 1500, Ph 5.8.
To my surprise, the ph only went up to 5.8 & the ppm stayed the same.
The tips of the leaves are showing new signs of nutrient burn.
So I added ½ gal r/o water to each bubbler.
This brought the ppm down to 1500 & left the ph at 5.8.
I’m having a hard time keeping the humidity below 50%, even though I’ve got the humidifier on it’s lowest setting.
The lower I set it, the more the plants transpire, which keeps the humidity up.
When I turn the humidifier off, the temp goes up to 90f & the humidity drops into the 20s. Way to low. Hopefully I can find a way to remedy this problem.
3-4-04, Day #21 of Flowering:
Cab Temp 81f, RH 52%, Nute Temp 72f, PPM 1460, Ph 5.7.
The plants drank ¾ gal of solution since yesterday making the ppm go up to 1610 with a ph of 5.7.
I added ¾ gal of plain r/o water to each bubbler.
This brought the ppm down to 1460 with a ph of 5.7.
