Bubba Kush

This is my third run in the autopot XlL system and this is the first issue I've had. One of the Bubbas is unwell and hopefully I can get her back to church like her tentmates. I am thinking it was a result of a clogged valve. She looks quite sad at the moment and, of course, the hardest pot to get to in the tent. Pot fees full so not sure what to do. Nugs are still looking like they are forming well amd the healthy one is stacking up really nicely, especially for just hitting the end of week 3 of flower. Did a nice clearing of the larf under the canopy to keep airflow moving through. Might throw a few cuts into water to reveg as monstercrops. Ive tried this before and the plant structure gets CRAZY with all tje hormonal changes. Upping light a tick to 80% and following medium dosage of Canna A&B schedule. Light topspray of recharge water every few days just to keep topsoil moist. Happy growing!
