hey Peek,
No sweat man, first off let me say it's ok you did the flush, it doesn't hurt to wash your roots every month as it cleans the soil from salt accumulation. But then you need to replenish the soil with nutes you washed away with the salts, in a proper quantity for your current life cycle phase. It looks like vertical growth as stoped and your in full flowering phase, yeah? so I supose you already replenished or are about to replenish the soil according with the feeding chart.
some plants have bigger needs and others lower. that's why this charts are aiming for the average plants. You should try to increase your dosage on your "micro" and on your veg aswell, try this if you still have at least 3 weeks ahead: 1 week for results, 1 week for possible changes if needed, and the last one for flush.
You need to remove the dried leafs because they're doing nothing but stoping air flow and making your grow look dirty and generally not clean
epsom salts and cal/mag are a growers usefull tool
Hope it helps,
Initially I was removing all the dead leaves but every time I would remove one, another would die immediately. Eventually I let it be because I needed the plant to show its sickness for the pictures. As far as nutrients go, I've tried to give them as much as they can handle. Almost all my plants have a little nutrient burn. Once I notice it I back off. After reading the comments I'm thinking it has to be calcium deficiency. I was using molasses and that has magnesium but I spaced the calcium. I will make sure to use it more often and see if that works. I appreciate your help.
