3-19-04, Day #36 of Flowering:
Cab Temp 81f, RH 41%, Nute Temp 73f, PPM 1450, Ph 6.0.
The plants drank a gallon of water since the nute change yesterday.
The ppm only went up to 1450, but the ph dropped to 5.5.
I still haven’t figured out why the ph is dropping this late in flowering.
But I guess it’s no big deal since the plants look awesome.
Anyway, I added 1 gal of top up solution to each bubbler.
Here’s what I added to 2 gallons of water.
5 ml per gal Bloom
½ tsp per gal Kool Bloom
10 ml per gal ph up
After adding this to the bubblers, the ppm was 1450 with a ph of 6.0.
3-20-04, Day #37 of Flowering:
Cab Temp 80f, RH 43%, Nute Temp 73f, PPM 1550, Ph 5.8.
The plants drank ½ gal of solution & the ph dropped to 5.8.
The ppm went up to 1550, meaning the plants drank mostly water since yesterday.
3-21-04, Day #38 of Flowering:
Cab Temp 78f, RH 43%, Nute Temp 73f, PPM 1510, Ph 6.1.
The plants have drunk another gallon of water, leaving the ppm at 1640 & the ph at 5.7.
So I added a gallon of top up solution to each bubbler.
The only thing I added was 5 ml per gal Ph Up.
After adding this to the bubblers, the ppm was 1510 with a ph of 6.1.
3-22-04, Day #39 of Flowering:
Cab Temp 78f, RH 43%, Nute Temp 73f, PPM 1550, Ph 6.1.
Not much change since yesterday.
But I took a few pics & here they are.
3-23-04, Day #40 of Flowering:
Cab Temp 80f, RH 43%, Nute Temp 73f, PPM 1570, Ph 6.0.
The plants have drunk another gallon of water.
This ppm was 1570 & the ph had only dropped to 6.0.
So I added a gallon of top up solution to each bubbler.
Here’s what I added to the top up water.
10 ml per gal Bloom
After adding this to the bubblers, the ppm was 1550 with a ph of 6.0.
3-24-04, Day #41 of Flowering:
Cab Temp 80f, RH 43%, Nute Temp 73f, PPM 1500, Ph 5.7.
The plants drank a gallon of solution since yesterday.
The ppm went up to 1640 & the ph was at 6.1.
I’m going to lower the ph down a bit, I’ve had it pretty high for a while now & I want the plants to get the nutes they need at the lower ph for a few days.
I added 1 gallon of top up solution to each bubbler.
Here’s what I added to the top up water.
10 ml per gal Ph Down
After adding this to the bubblers, the ppm was 1500 with a ph of 5.7.
3-25-04, Day #42 of Flowering:
Cab Temp 80f, RH 43%, Nute Temp 73f, PPM 1470, Ph 5.7.
The plants drank about ½ gallon of water since yesterday.
The ppm dropped a little & the ph went up to 5.9.
Since the plants drank slightly more nutes than water, they must have needed the nutes they were able to absorb at the lower ph.
To get the ph back to 5.7, I added 1 ml per gal Ph Down to each bubbler.
This brought the ph down to 5.7.
