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!
