First soil grow, under lights.

You are feeding every day? I'm surprised you haven't had any nute burn yet, but in my experience, vegetative plants are super durable and can absorb more nutes than when in flower. You are not in flower yet, so that may be why. I have no experience in plastic pots, but is that frequency because your higher temps are drying out soil faster?) If not, it may mean you will eventually water log those plants. I use fabric pots, but the 2 knuckle approach with your finger in the soil, should tell you when to water. Should be cool, but not damp.

"cant hurt i use 2 1200w and 1 600w in a 3x3 with no problems and i get nice tight buds.".. Technically speaking this should be way overkill and should be burning plants. But most likely underpowered and cheap leds so that's why he gets away with three lights. I'd never recommend putting 3000w of "rated" power in a tent that small. As for your situation it's always worth an attempt.. they will tell you pretty quickly if it's too much light. Only a day or so is all it takes and you will see burning where the two lights meet and it's most intense.

Not sure about sprays but them sticky pads work well, just stick them on top of your soil or hang em in your tent

Yes I'd say 30-80 is a Fair assessment. But like 3 plants between 90-240 is a huge variance but there are just too many variables to really "accurately gauge" what your gonna yield.

Hey fluffy, Great growth in the last week. I'd definitely get in there with another clean up of the bottoms. All 3 plants have such nice full canopies that I'm sure they'll block a fair amount of light from the bottom. It's hard to cut away all those bud sites but you're at the best time in the grow to redirect that energy into those topmost buds. I usually go through my first lollipop and always end up realizing I should take away a bit more. Happy flowering.✌️
