low pH problems
I discovered that I had irrigated with water at pH 3.5 for at least 5 days. yesterday I used water at pH 5.7 and today I think it will increase to 6, but I noticed that burns are already starting to appear so should I continue like this and hope for the best or do a root wash?

Dry and Liquid Organic Fertilizers
Hello fellow growers I have been curious if anyone has used both liquid and dry fertilizer in their grow? I am growing in Coco and using a super coco mix with top dress and tea with dry fertilizer. If I add liquid fertilizer would this kill the living microbes in the coco?

When to start flushing
Should I stop adding nutrients and just give the plants plain water now? I'm in Week 8 and many of the FastBuds Pineapple Express Auto grows I've seen harvest around week 10. Would switching to just water be a sufficient flush?

Nutrient lockout? [first grow]
My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before. Is it nutrient lockout? Or just deficient? Appreciate every feedback!

Water
Is it bad to make my water ahead of time ? I mixed my nutrients (big bud, formulex, bud candy & molasses) in with the water & have let it sit out for over a day. I heard letting it sit out gets the chlorine out (I put a towel over it though so my cat/other stuff would get in it)

How long left?
Hey all, first grow seems to be going ok, despite me being clueless! Now at 8 weeks and 2 days and wondering how long I’ve got left? RQS say 9-10 weeks total. Still a bit to go - only a few hairs turning brown but would really value input on when to stop nutes? Thanks
