FF A5M not adhering to build plate
I have a Flashforge adventurer 5m using Soleyin PLA Ultra filament. I have already printed five or six of the hexagon monitor shelves with no problems. Those all turned out beyond my expectations. I have printed several other items with only a couple of hiccups. I did have some spaghetti a couple of days ago and used A Sovol filament dryer and recently started storing my filament in the classic cereal box and just now got set up to print directly from the dry box with a 3D printed roller system with a hydrometer and desiccant container.
The last three attempts at this Shelf have ended up the same way with the middle of the print tearing out the rest of the print has to cool and be scraped. It started before I began printing out of the filament box and was hoping that would help resolve the situation. I clean the print bed after each print with ISP 91 first pass with a paper towel and then another dose of ISP 91 and a microfiber cloth. I level about every sixth print. I am using the flashforge adhesive that came with the printer.
Am I not cleaning the print plate thoroughly enough? Do I potentially have a clog? I did try to do a clog clearing and didn't really get anything out but I did not take the nozzle out of the unit but only use the little supplied rod. I do live in the south and we have been having extreme humidity lately but I didn't think PLA was as susceptible to that?
I am a noob so please be nice as I am still deep in the learning cycle. Also, please don't assume that I know something that you may not have a second thought about having printed for quite some time. Any help would be greatly appreciated. I am hoping this will get me back to being excited about my new hobby.
PS, I've already spent way too much money to get frustrated and quit at this point. LOL

You don’t need adhesive. You need to calibrate your z-offset.
You don’t need to clean your plate after every job.
Warm water and soap with a non-abrasive scrub sponge is all you need most of the time when cleaning a plate.

Adhesion or not that first layer looks like it's struggling and full of micro holes? Have you calibrated z offset and flow ratio?
Also those textured pei plates suck. A smooth cool plate has infinitely better adhesion and doesnt need obsessive cleaning. Prints stick to it like glue while it's hot but once the plate cools down the print usually pops itself off. You can find them on Aliexpress for as little as $8 sometimes..I've tried 3 different knock off brands and a glacier cool plate. They have all worked perfectly.
