Hey Guys,

Started noticing new problems with my plant, little purple/brown spots on older lower leaves that are starting to curl up a little, unfortunately i couldn't get a good pic of that due to light but i did get some of the top which shows the upper yellowing.

Also i have not flushed yet when i replace the solution every week, i water it every 6 hours for 5mins. Do i flush by replacing this water with newer diluted stuff for awhile or do i just take a bucket to the pot and let it all drain out? (maybe its a toxic buildup?).

Any help would be great, im still pretty new at this.

PS: i also noticed the leaves that are the most sick are its original leaves it had from cloning with no buds or anything, do they just die off after awhile maybe?
