Recently bought some Jack Herer autoflower from Robert Bergman, so I figured Id join the forum and post my grow. Its my first grow in about 8 years, however my first grow 8 years ago was in a closet with no ventilation, I used the wrong soil from the start and let the temps get way to high so it wasnt very successful… Then I got an electrical bill for around 500 dollars from using a 400watt HPS/MH Light so decided to just give up.
Fast forward now i have my own place and recently built a stealth grow box that looks like a dresser that has a 30" x 36" Vivosun Grow Tent Inside and is fully ventilated to the outside with fresh air-conditioned air being pumped in by two inline duct fans and out by a Carbon Filter. Temperatures never get higher than 82 degrees when lights are on and stay around 74 with lights off… Humidity ranges between 40% and 60%. Lighting is a 450 Watt Viparspectra Full Spectrum LED Light with Veg and Bloom Switches which are on for 18hrs a day.
Im using a soilless mix from a local plant store I added extra perlite for extra drainage in 2 gallon containers. I planted the sprouts directly into their medium as read autos do not like transplanting… They popped out of the ground the next day: DAY ONE
I made the mistake of overwatering from the beginning because I thought it was a good thing to completely soak the medium at first. However i think now i should have done smaller lighter waterings when the plant is so young because it took about 2 weeks for the soil to dry out enough for me to water them again. It kind of threw off my nutrient schedule because they flowered so quickly I never really gave them any veg nutes. Ive read that this is a normal thing but i was a bit unsure because my soil had no added nutrients to start, would that later on lead to signs of nitrogen deficiencies, (Hopefully Not)
(DAY 21) Shorter one starts showing Pistils
(Day 28) Taller One Showing preflowers Shorter One flowering further develops.
(DAY 34) Taller One got too tall and needed to be tied down a little (LST) style… First time Ive ever had to do this, and I like the way it promotes growth from the lower flowers. Shorter plant is thriving and looking beautiful and is at the perfect height.
So at this point my waterings have been:
1st: PH Balanced water (No Nutrients) 8/6
2nd: PH Balanced water (1/4 tsp Big Bloom) 8/20
3rd: PH Balanced Water (1/4 tsp Tiger Bloom & Pinch of Grow Big) 9/04
4th: PH Balanced Water -Tall Plant (No Nutes) Shorter Plant (1/8tsp Open Sesame 1/2tsp Tiger Bloom) 9/09
Run Off PH levels are: Taller Plant- 6.7 Shorter Pant - 6.3
Im really happy with the grow so far and am having fun experimenting with the nutes but any advice from the gurus would be appreciated.
Only signs of deficiencies so far is that the tips are curling up just a tiny bit which is usually a sign of over nutes but I find it hard to believe thats the case here because I’ve used them so sparingly, so I’m thinking that it could have been a little heat stress from earlier in the grow before I had the ventilation system complete.
Also the very bottom level leaves are yellowing but i know that this is normal as most energy is being focused on the upper part of the plant.
So again any advice on nutrient feeding is highly appreciated. I have Grow Big, Tiger Bloom, Big Bloom, Cha Ching, Open Sesame, and Beastie Budz. Im basically following the schedules that are out there but some recommend plain waterings in-between feedings. However Im using a soilless mix so maybe I need continuous feedings throughout the whole flowering process. I just looking for signs from them but always welcome advice from the pros!. I will keep this updated as I can.
