Indoor Second run, I think I over did it....

[Cyph3r]

Please fill in this form: (copy and paste part is below, this first one tells what specifically to include)

-Problem: Started with yellowing lower fan leaves, then progressed to what looks like nute burn (probably my fault)
-Medium/grow method: Soilless Rootfarm https://www.rootfarm.ca/products/hydro-garden-potting-mix/ in 3gal fabric pots
-Feed and supplements used: General Hydroponics Flora series: Micro, Veg, Bloom, watering every 2-3 days
-Water source: tap, sits in 2x 5 gallon buckets with airstones for 48hrs before nutes are added Water PH'd to 5.8-6.0 before watering (after nutes added obviously)
-Strain and age: 5 weeks - 3x bruce banner, 2x blueberry, 2x dwarf mystery strain
-Climate: temps between 75 and 80, usually around 77, RH between 50% and 70% averaging around 55%
- Light used: 2x 1800w LED 1x 1000w LED added at start of flowering, lights approximately 24" away from top of plants.
-Additional info: Lowering fan leaves started yellowing around 1 week ago, it looked like a nitrogen deficiency so I increased the dosage of nutes from 1/4 recommended dosage to 1/2, the yellowing spread to upper leaves and 1 bruce banner looks like it has nute burn. I'm not sure if I had PH lockout originally, or more likely I believe I was letting the medium dry out too much between waterings, it would be pushed off the side of the fabric pot so I think there was a nutrient deficiency but because the plant wasn't getting enough waterings, I flushed with 6.2 ph water, calibrated the ph meter in 7.0 solution before to be safe (it was off).

--Pictures I will include more when I get home, but here's some I took with my phone last night when I was panicking lol
MYSTERY DWARFS (2X)

BLUEBERRY (2X)

BRUCE BANNER (3X)

WORST OF THE BRUCE BANNERS

Now based on some research I'm leaning towards nute lockout, I was under the assumption this was coco based, but it is peat based, so I think my ph is way off!

I would say you are correct. Your pH needs to come up. I’d be looking at 6.4+ but I’m a coco grower so you might want to confirm with another on soilless medium pH. The nutrient lockout will likely be a few types so I wouldn’t focus on supplementing any particular one. For the age of the plants and stage of development you will probably want to increase your nute strength when they get back on track. Remember that the yellowed leaves won’t correct so you may want to cut them off. Look at how new growth progresses.

Usually, when running hydroponic, we track pH in, in pot, and run off. Ppm of the 3 as well. I'm usually looking for a ppm 3 to 800 in the medium, just prior to feeding. Under 300 and your close to underfed, over 800 and need to back off slightly. Medium pH in coco 5.8 to 6.2, soil, 6.4 to 6.6, I haven't used peat, but I have had it mixed into soils... as it breaks down, it tends to drag the mediums pH down, when it did, it happened about week 4 or 5 of flower.
