Looks like these plants need more vegetation than I thought. Bit more light and bit more fertilizers. EC from 0,96 to 1,11 and lights DLI was 27, now DLI 32.(for 18h) There is one led with 3500 Kelvin and other one 5500 K, which is better for vegetation. Scrogging net can also wait more.
Thu, 30.1. Roots have been grown and leaves are getting bigger so fast. I adjusted the lights better and DLI has been set 34.
Fri 31.1. I’m gonna flip the lights to 12/12 tomorrow.
Lights have been flipped to 12/12. Nutrients are still for vegetation. Going to change them in couple of days.
3.2. I started giving flowering fertilizers. EC1.02, Ph5.9, DLI32
4.2. EC 0.98, Ph 6.1, Rh60%, Reso24C, Tent23C, DLI 30. Growth is huuge
6.2. EC 0.97, Ph 6.0, Rh62%, Reso23C. Tent22C, DLI 30,
8.2. The growth is tremendous. I hope my 6000 K supplemental lights will keep the growth in check. EC 1.01, Ph6.0, DLI 30, Reso 23C, Tent 23 C, Rh60%. Emerald Harvest's first week of flowering fertilizers are still in use.
10.2. The lowest leaves need to be thinned out. The plants are evapotranspiring so much moisture now. Ph 5.7 is on the decline and I don't understand why. Plants absorb so much nutrients that EC drops by 0.05-0.1 units in 12 hours. The plants are growing so fast now that I have to be careful with the lights. The DLI was 35, so I raised the lights a little. DLI is 31 now. Using Emerald Harvests 2 week bloom nutrients now. I diluted the mixture so that the EC is around 1.0
13.2. The pH is on the decline. It was pH5.6 (!) I raised it to pH6.1. EC 0.98, Reso24C, Tent25C
17.2. All the girls have started to bloom. The pH was dropping. I changed the fluids and now the pH is rising. 🤷♂️ Emerald Harvest is a buffering fertilizer and you probably shouldn't measure it. However, I can't help but measure and worry. EC 0,98 and pH6,6.
19.2. The lights had to be reinstalled. Now the tops get more even light. DLI31-35. DLI measured with the Photone app on a mobile phone and a selfie stick. I'm not very skilled, but the tops of the plants are pretty even. So far.
22.2. Emerald Harvest flowering week 4 fertilizers according to the instructions. Diluted so that EC 1.11. The main growth phase is over. PH 6.1, Reso22C, DLI34, Day 25-26 C, night 19-20C. All seems to be fine. I added a Hailea water chiller a couple of days ago. The plants seem much more stable.
25.2. EC1.08 pH5.8. All good. The most problem-free growing so far. Still time for problems here.
26.2. EC1.08 pH5.9 Added couple of pics. All good
1.3. Bloomday 28, all good. Liquid temperature reduced to 20 C. Small flies appeared. The temperature in the tent gets too high.
2.3. Bloomday 29. I changed the water. 2 pumps for NFT and 1 for the water cooler. The Netatmo thermometer says the same as the IR thermometer: 26 degrees Celsius. EC1.01
7.3. Bloomday 34. Spring is coming too soon so I have some problems with temperature. Keeping it 26-27C but lights DLI is only about 35. DLI could be 45 without temperature problems. I have to add water about 3-4 l per day. EC1.05
15.3. Blooming week 7 started. I reduced the light to DLI 35. 40 would have been too much. Growth is slow but the girls look healthy. I have never grown anything this sticky. 😀
17.3. Something is going on because the smell has increased massively
22.3. Blooming week 8 has started. As before, the fertilizer mixture was made according to the instructions for week 8, and then diluted to EC1.15. I tried EC1.3 before but the tips of the leaves started to dry out immediately. I switched back to EC1.1. It's quite mild but this is a sativa strain. Everything has been going strangely well. I guess the water cooler is much more useful than you might think. About a month more…
I added one 6000 K light for one plant that looks like it’s gonna grow 3m high. 😅 6000 k reduces the plant's desire to grow. Other led 3500 K is better for blooming.
DLI 33, EC 1.04, Ph 6.0, Rh 62%, tent 21.5C, solution 23C. I’m not sure when I should start blooming. It’s day 8 when plants are in NFT. Maybe couple of days, I think?
Looks like they are starting to grow pretty good. They were couple of weeks in the closet, and I was worried how they will survive. Now some LST and maybe week growing before switching to blooming-mode.
