bombs wont stop them, soaking them in the tub will only help further the lockup thats coming, the afids affect the plants water and food uptake.
You cant go into flower infested, the problems get worse from here. this is a large grow with a large problems. Seriously what is 5 bombs going to do. there are thousands of those in the roots. there are new life cycles every week.
From here the nitrogen uptake will start to lockout, first at the lower portion, then a even yellowing over the plant. further treatments usually only serve to hinder this population. however the damage is done, in this period of flower nitrogen level are low making it hard for the plant to repair the root system.
As a result your plant production color and vigor turn off.
the plants yellow and become more weak, mites and other pests come in.
Afids are one of the most distructive pests for the indoor gardner.
if he doesnt kill the bugs in the dirt, and get the dead tissue out or nitrozyme or like product into the root mass there will be no repair.
If the plants get weak it will be a very sad ending to a high profile grow.
6 pounds from sick plants will be a tough mark.
its a hard battle,
Now with root problems, fungus, high humidity, its becoming a recipe for disaster.
