Setting up dtw coco 2.5x5 tent

Happening again but on another plant. I at a loss. Wont know till I unwrap at harvest but I doubt Il see anything. What could be happening this early. Thing is I dont look at it from planting til harvest so roots or salt build up or mold growth idk. Somethings clogging it. I dont think its the pumps either.

Its the drippers inside the sealed pots. They have splitters on each. Two lines per plant.

Again… Its the pump I think though. Its pumping slow then spits out again as should. Plant suffered. This pissin me off greatly. Never happened before. I blew into the tubing it was somewhat restricted which is another sign of whats going on. Like it was too restricted so the pump just went into limbo.

like if the pump cant pump freely it just goes to limbo and the port manifold is barely flowing. I blow tubing clear and it spits again but I dont think thats why though its not helping. WTF

Anyone feel free to chime in. Why are my punps not working.. When the pump works it creates way more pressure than I can blow. Sometimes its fine, sometimes I feel it somewhat clogged and then it gurggles clear like bubbly this time vs something hard clogging it. Last time it felt more hard like pearlite or coco but this time gurgly bubbly.
