pests late-ish in flower

Is your thought that nitrogen metabolism has slowed / stopped because of heat and lack of micronutrients and are you basing the statement predominantly on the presence of bugs? I will lower the temp, but won’t be able to get it down by much this round since the envelope room is prob 74. I can turn the light down and if feeling ambitious, can move the driver to outside the tent, which should be worth a few degrees. Regarding the nutes, the only thing I have been feeding with is Foop Canna, which is derived mostly from fish poo, kelp, sea water, so is very diverse. They don’t list all o the micros individually, but I would expect most of the above bases are covered. The sweetener def has 8 sugars. I have a copy other things I can add as well to better ensure diversity. My concern is I only have a couple of weeks until full maturity, so a plan like this, which is the kind I am drawn toward, likely takes more time to have any effect than I have. Good info nonetheless. Thanks!
