Looks, great man. You are doing a lot right for your first time out the gate. Very impressive. Your temps right now are perfect. Through all my experience we find that buds formed over 80 degrees will be big yes, But very airy and prone to fox tailing. They will also never cake up as much as buds formed at lower temps. We find that lights on mid 70's to high 70's for the first 4 to 6 weeks depending on the strain & no more than 9 degrees less with lights off. Once the plants have finished growing vertically we like to open up that temp gap to beyond 10 degrees between lights on and lights off. Usually, this has occurred by weeks 4 to 6 of flower depending on the strain, Obviously sooner with autoflowers. Once this has happened allowing for a larger temp swing between lights on and off will send a signal to the plant to put extra energy into its budding process and resin production. Doing this prematurely while the plant is still growing will cause it to instead stretch, That is why timing is key.
This is a good rule of thumb but with more intricate manipulation you can take advantage of both size and density. As the buds are forming we can run temps of up to 82 and then as soon as cake begins to show and the buds are now swelling we drop that temp down to the mid 70s and begin slowly walking it down each week as we finish the crop off. This will give you nice big buds but also will carry with them good density. Size is great but the weight comes from dense buds which form more at lower temps. Enviromental manipulation plays a huge key in how we develop our buds and how they will form.
If you do not have them already get yourself a thermal temp gun and a PAR meter to read the tops of your plants and dial everything in as optimally as you can. These pieces of equipment will really help you get the most potential out of your lights. Keep up the great work man and if you have any questions please do not hesitate to ask me.
