Wedding cake was slow to start and is now taller than the Sour Diesel.
Light Intensity 40% and 18" away.
Keeping 72° ish and 70% rh results in VPD near 0.8.
Humidifier on low and exhaust set to 2. Off at night for both to maintain humidity.
Watering about 2 cups or less for each plant every other day.
Wedding cake is now bigger than Sour Desiel. Fed 1 Gal w nutes to each, based on the GH Photoperiod "Light Feeding" Schedule Week 1.
Increased light from 40% - 60%. I will raise the light next week as they are starting to get taller.
Update: Sour Desiel is looking really deformed now. It's had wings since the beginning but now growing completely sideways.
Increased light and lowered humidity.
Wedding Cake is looking really good. Sour Diesel is bouncing back and only slightly behind in size.
The wedding cake already has a nice smell in the morning. Sour diesel has no smell.
I'm using Armor Si as foliar spray (1.5mls per liter - spray bottle is 1 liter) the day before watering.
The WC is still growing a lot quicker than the SD, but there are some issues I've ran into. The WC new growth is light green, there are rusty spots on some of the leaves, the tips are burnt(white or yellow), the runoff last watering started in the high PPMs of 5k and pH of runoff started around 4 and went to about 2k ppms and pH 5. The last watering I did a couple days ago was 1/4 strength of what I gave previously at pH 6, to help rinse the salts out that could be causing the ph issue/ppm issue.
The wedding cake has started producing white pistils but the SD is still small and no sign of pistils yet. I plan
The exhaust on my tent was set to exhaust at a certain rh% but the probe went bad and the exhaust did not kick on. The plants were were in %80+ rh for the most part of a the day. Vivosun sent me a new probe but i wont be setting it up like that again. Dehu on the way to keep rh low.
WC still filling out and SD very dense and looking frosty. I'm slowing increasing bloom(PK) and going to dial back micro (N). Trying to catch up on my weekly posts
Slowly backed off the nutes until I just did plain water. When it was time for a drink the dechlorinated water I had was outside in the cold. So they got a nice chilled drink of 2 gallons each. About 4 days later they were pretty dry and gave them a flush of the substrate - 4 gallons of PHd water each (6.0). I would like to see the fade before harvesting and it has finally started on day 81. I plan to water once more in about 3 days and let them dry out and either pull them both or the SD first because WC doesn't look as far along. I will make that decision based on the trichomes. The finish line is in sight. Oh and I also started cooling the lung room so the day and night time temperature has dropped to simulate the end is near. About 60° at night and 68° during the day (numbers from inside the tent).
Hey wassup!
I’ve noticed, that you are feeding your plant very low amounts of nutriens.
In total you are giving them 144mg/Gallon nitrogen, 125mg/Gallon phosphorus and 180mg/Gallon potasium.
Convertet to Liters you are giving them an npk of 38,08mg/L N, 33,3 mg/L P and 47,6 mg/L K.
An Ideal amount of NPK during Veg for cannabis according to credible studies is 160-190mg/L N, 30-90mg/L P and 200mg/L K.
Alot of these Nutirens are necessary for the development of your plant so i would suggest the following formula:
7,5 ml/Gallon Tripack Grow
7,5 ml/Gallon Tripack Micro
You would then be feeding:
160mg/L N, 40mg/L P and, 140mg/L K
You could use 3,5 ml/Gallon of Flora Bloom if you want to push the potasium a bit higher during Veg for more root developement. but make sure it‘s in that range because otherwise the phosphorus gets so high that it hinders secondary metabolism during flower. Same with potasium.
Sorry for the long comment but i noticed some discoloration so maybe this would help 🌱💪🏻
@SimpleGrow, suprisingly this is making sense! Haha. Once I calculate each fertilizer (NPK percentages, as well Cal and Mg) those numbers stay the same per each bottle of fertilizer. Then calculate the weight of the nutes in mgs per ml?
@djclean808, great 🙌🏼, it‘s very intuitive when you get the gist of it. :)
I always start with the total weight of the substance in my fertelizer and multiply it by the percentage I’m using (4ml of 1000 would be 0,4% so times 0,004) you will get grams so you‘ll have to convert to mg wich is 1/1000.
@SimpleGrow, wow just did a little research on it and understand what you mean about mg's. Which is also ppm/l. So definitely going to dive into fertilizer calculations now 🤯 but I actually like doing math!
