So, I'm wondering if I should have named this thread "Profgrow makes big mistakes so you don't have too"
I once again get to admit to a failure I have made and how it has effected my grow.
I will preface with this; The last 2 weeks have been rough to say the least, between car problems keeping me away from home longer (taking buses etc) and weddings/holidays taking up exorbitant amounts of my time (my lights running while I'm at work doesn't really give me a lot of time to check up on things either).
The nutrient burn wasn't nutrient burn.... it was ph lock... Yes, I know "hey prof, how do you get ph lock in hydro?" by being a baddy is how, person I just made up....
I had taken Ph readings from both my reses, leaving my meter under the drip ring for a few min to get a solid reading, the drip rings are way under there so its hard to see whats going on. Long story short I was getting false readings because I was effectively sticking my meter in ph down concentrate while my res water flowed over it making it fluctuate as if it was under water only.
On a hunch I took a direct reading... 7.6... now, I have no idea how long this has been going on, I assume a few weeks. It explains the tip burn as if I had been over nuting, most of the damage is on the left bush and that was the res with the higher numbers (right res is holding around 5.9).
The damage isn't severe but it will hurt my yield slightly. I did a full exchange and wiped the residue from the drip rings, running lower nutes and 5.8 ph, hopefully this sticks, there was some algae in the res but very little, I would use a bit of peroxide but I want to see if she mellows out.
Really hoping I can get this under control, this is the one downfall of hydro; mistakes cost a lot.
