08/10 - 10l nute water top up, then I noticed her leaves had some spotting which identified as nitrogen toxicity. Dumped the res, ran clean ph water for a couple hours, dumped that res and then refilled at 32% strength. 25ml Micro, 4ml Grow, 35ml Bloom. Will see how she does.
09/10 - PH bumped to 5.8.
10/10 - PH has been plummiting, but I think my pens busted. Ordered a new one next day. Topped off with 8l of water at 40%.
11/10 - PH pen was indeed busted. New one just arrived and PH was around 4.7. I've now bumped it back up to 5.8.
13/10 - Full Res Change. Ran ph water for 3h to try and flush some N before adding 25ml Micro, 5ml Grow, 40ml Bloom. PH at 5.75, EC at 1.15. Some leaves at the top of the canopy are dying off due to the Nitrogen tox causing Cal lockout which is unfortunate, but hopefully she gets back on track with the nutes dropped back somewhat. Shes still growing, now at 11" from the light, and the buds are fattening up decently.
14/10 - Ph and EC stable! Debating a W6 flower defol.
