SOIL Need advice on bloom fertilizing

[hawg1944]

I have several photoperiod plants that are about 7.5 feet tall and very bushy. I have been feeding Super thrive GROW and they are beginning to show signs of flowering. For the past week I have been feeding them Superthrive BLOOM with their waterings to encourage flowering. I was curious how often I should add the BLOOM to their water 1/2t per gallon It is 3-12-6. They are in 15 gallon containers with good drainage and we have had an exceptionally long drought here in S. Ohio so they go thru water 3-4 times per day on these 90 deg. days. I also have Miracle Grow Bloom Booster which is 10-52-10 that recommends feeding weekly or bi-weekly but have not used it yet. I was asking for any advice on how much, how often and which strength I should use to encourage and boost the flowers. Any advice is appreciated as I am a first
time grower. To stay in compliance with Ohio's new law they are in an unused dog kennel that I can lock and keep from public view.
Thank you

Sun, genetics, airflow and temps & humidity & stress will dictate the size of your buds, not your bloom booster. That has just about zero to do with it unless you stuff it up.

Just give them what they need by reading your plants. They will tell you what they want. Half strength nutes every second day is an often good starting point.

They are looking great too.

Thanks that is a help. I was using the Super Thrive based on the newsletters from this site and from the size of them it seems to have done a great job. The Bloom was also recommended but not amounts. This gives me a benchmark to start with.

In a soil grow Don't let the water pour out the bottom of your pot as this washes away all the goodies the plant needs.

When you see it starting to flower slowly start your flower nutes at a low dose and increase it to about a half dose over a two week period or thereabouts.

Keep a close eye on your plants to see what they need. A plant that size in that size pot is going to need watering every three or four days and more frequent in hot/windy weather. Maybe more often if they are air pots. Over or under watering is probably the most difficult thing to get right in a soil grow.

They are in fabric pots that have worked well. I have never had water run out of them but they do go through a lot of water in this heat. There is a layer of super soil and then filled up with Fox Farm coco soil.
