Welcome back to day 6.
Now that you have vegetated your plants for a month and they are now 18-24 inches tall and have several tops, are bent over, and the bottoms are cleaned up, you are going to send them into the flowering phase. Be sure to test the temperature in your grow tent by making sure that it will be at about 75 degrees or below with the lights on. In veg it was not as important to keep the temperature down, but with bud creation it is much more of a necessity to keep the temperatures down as this will aid in trichome production, prevention of bugs, mold, heat stress to the plants, etc… Change the time on the timer you had previously set from 3pm-9am to be on from 9pm to 9am, an off from 9am to 9pm.. (on 12 hours a day and off 12 hours a day.) If you are confused on how to set the timer up, ask a hydroponics shop.
The reason for flowering during the night hours is that it will be substantially cooler at that time. The fresh air you bring in from the outside and suck through your 1000 watt hood will be cooler, and it will be less work for your A/C to cool your grow tent.
Raise your nutrient solution of your BioThrive Bloom to about 1000ppm’s in your reservoir with the tap water before you add the Golden Tree.) Raise your dosage of Golden Tree to 5ml/gallon. Steer clear of reverse osmosis water for now as it is unnecessary. During the next 9 weeks or so gradually raise your BioThrive Bloom ppm’s from 1000 to 1300 in your 5 gallon buckets which carry your mixed nutrient solution. If the leaves start to burn a little bit, edge back a little bit on the BioThrive Bloom, but do not edge back on the 5ml/gallon of the Golden Tree. It is possible you may or may not also need Calcium/Magnesium supplementing, but considering you are using tap water, you probably should not. Google “Calcium/Magnesium deficiency marijuana” for more information on this. Also, it may be possible that your plants can take even more base than 1300ppm’s, so if they are not burning and look good, keep raising it until they begin to burn and then edge back.
Some additional info:
Also, read up on EC and PPM. You will need to understand the difference between the two to understand the pen you are using.
Adding 5ml/gallon of Golden Tree increases the ppm’s by about 200.
I would suggest not buying a dehumidifier, as your A/C already acts as one. Dehumidifiers are a pain as they generate heat and you have to dump out the collected water often. You need to pay attention to simply feeding your plants every day and making sure they look healthy. Make sure air circulating through the tent with a small fan present in the tent faced towards one of the walls, and keep the temperature in between 65-75 degrees.
Every week continually clean up the bottoms of the plants so that the only growth that is present where buds can occur is in the top 1 1/2 feet. You want all the energy of the buds to be sent to the top of the plants.
During this 8-10 week process of flowering there are some things you need to watch out for. Watch out for Powdery mildew spots of appearing. If you find a powdery mildew spot on any of the leaves, which is quite common, you will need to buy a sulphur burner at the hydroponic store along with some sulfur. You will need to hang this sulfur burner at the top of the tent, and when the lights are off between 9am-9pm, you will need to turn it on and let the tent fill with sulfur smoke for a few hours, and then suck out the air after by removing one of the ducting connections on the light (this fan is already on sucking air outside, and by removing the ducting form the light, it will suck out the air from the tent. You will need to do this once every week or so to be sure that no powdery mildew will form again.
If you experience bugs, which is also common, you will need to set off a bug bomb, letting the tent fill with smoke for a few hours, and then remove the smoke by again removing one of the ducting connections on the light.
The later you go into flowering the heavier the top colas are going to get. You will need to tie the branches to a stake to keep them upright, or else they will fall over. This can be tedious, but quite fun when you start to feel all of the weight that is being added!
Flowering can take 8 weeks, and it can also take 13 weeks, so watch your plants and know the tell tale signs of when your plant is ready to be harvested. You must be very patient and not cut the plants early or else you will jeopardize the quality of your crop. You probably are andy to cut it down, harvest it, and get the money for it, but you must be patient. We will go over that in Day 7.
