D27: [22.2° 77%am] [25.9° 71%pm] Today I am adding 50ml of water at 400ppm of NPK liquid nutrient solution to start this new week with some bump of nutrients and to wet the soil a little bit. The probe is still showing wet since last big watering so I am not adding that much more water. The weather is still cloudy and not that much sun. I miss those sun bathes she was having.
D28: [22.8° 78%am] [24.5° 75%pm] Even without the sun she is getting bigger everyday and the new leaves are coming out one after another. The mosquito traps and neem oil are still in transport and I am killing those insects manually everyday.
D29: [24.2° 76%am] [32.7° 59%pm] Today I added 150ml@450ppm water around the center to moist the soil. The probe only picks the deep soil values and I was worried that the top part was already too dry.
D30: [24.4° 75%am] [30° 57%pm] Finally the mosquito traps arrived yesterday during afternoon and I already set one up for overnight. I have added the close picture of the mosquitos getting caught in it. I am really loving it LOL. I have also made the solution with neem oil and sprayed around the soil during this morning to combat the early stages of the fungus gnats. Lets see how effective this will be during next couple of days. She is now passed 9cm tall and I am really proud of her. She is really beautiful and her leaves are nice colored and shaped.
D31: [23° 77%am] [23° 76%pm] The weather is really bad this week and almost all day cloudy with no sun. I am worried about her not getting enough light. Anyways, the fungus gnat is reducing abruptly. I wouldn't expect the neem oil to be that effective and I am really happy that I bought it. Today I added 300ml@450ppm around the center to moist the soil.
D32: [21.2° 75%am] [25.2° 67%pm] Today I could let her get some direct sun during afternoon and I feel she really liked it. The soil is drying out and I think tomorrow I will feed her some more water with nutrients.
D33: [20° 70%am] [25.3° 55%pm] Today I could let her get some morning sunbath and maybe during afternoon we will have more sun. [spoiler, it didnt =(]
I have fed her with 900ml@450ppm and the soil is now all wet. I think I will only need to fetch more by the end of next week based on previous weeks. Lets see how it goes. Today is the last day of her third week and I am really proud of her development. I have made a side by side picture to show her progress =)
Would you be alright with me offering you some generalized pointers & advice to help you out? So cannabis plants LOVE heat and humidity. It is the buds that hate it, Early in veg we want nice warm temps like 79-84 MAX with lights on and no more than 9 degrees less with lights off. If we allow for too much of a temperature swing between lights on and lights off this will encourage our plants to stretch more than we want them to. So we try to keep those gaps in temperature tight through veg and early flower. When our plants are small, So are their roots. When our plants first start out in seedling stage or young plant stage they generally grow fairly slow because of this. If we introduce some humidity into the environment for the leafs to supplement the roots with some foliar intake we can speed ourselves along through this stalled-out stage of growth. The humidity of 60-70% works great for the first few weeks. If you do not have a humidifier get one they are just as important as dehumidifiers for growing. In the meantime you can also use a bucket full of water with no lid on it will passively raise the humidity up fairly well.
as you are in flower now it is not important but for the next time something to think about for sure. When we are in flower how our buds develop is largely based off our temperature control of the room. If we grow our buds too high of temps we will get huge big buds but they will be very airy and prone to foxtail. You will also lose out on a lot of cake, If we grow them too cold we get extremely dense nugs and very caked but lose out on a lot of size. Density + size is what we want for our weight to be right. Temperature ranges of around 77-80 MAX with lights on and again no more than 9 degrees less with lights off.
Once our plants finish their vertical growth by weeks 4-6 of flower depending on strain and with autoflowers you watch for it by eye, Once this happens now we want to begin to widen our temperature gaps between lights on and off to beyond 10 degrees less and a bit more each week until harvest. This will now instead signal the plant to put extra energy into the budding and resin production. Using light deprevation in the last 2 weeks to simulate cloud cover works well & doing a really cold feed on your last flush before pull down works great too. These are all enviromental triggers to cause the plants to react genetically as to produce the desired traits we wish to draw out of them.
Check out something called Vapor pressure deficit & how it relates to growing cannabis. All new growers should familiarize themselves with it and learn to use a VPD chart and log their rooms numbers every day. If you do not have them yet get yourself a PAR meter and a thermal laser temp gun like the fluke 62 MAX to better read your plants needs and grow to them. If you should need any help please feel free to ask, Just follow my growdiaries profile & shoot me a message! I am currently producing a youtube tutorial series for all levels of growers to utilize.
