Homemade inputs???
What do yall think of my diary? All homemade inputs, I invest literally less than 20 bucks in my inputs in the entire grow. I want to prove to you all that you do not need to drop money on bottled nutes, remember bottles are for babies. Challenge me? Just look at my diary

Rust-colored margins and dots. I would like to go back to fertilizing but I am afraid that it is an excess of potassium
Outdoor in the vegetative phase, southern climate. Soil is Biobizz light mix. So far I have only fertilized 2 times with the tripack ph perfect Advanced Nutrients. These rust-colored burns are present on almost all older leaves. Enlighten me please 🙏

Strange spots appearing on dying leaves
What the heck is going on here? Can't tell if this is some kind of deficiency or a fungal problem, it has been very humid as of late where I live and sits around 70% RH and 80°f

Possible pH issue.
(15th photo) I've a few leaves which are not looking the best. Does this look like a pH problem or does anybody have other info? I have dropped a bit of lemon into this plant which is the only one with this issue which has not touched the other 2 plants under the same regime. Tx

Nute burn or pH Flux
Ive noticed the tips are the faintest of yellow. Maybe ive mistaken Nute Burn for pH Fluctuations? Diagnosing: pHing both tank and run off showed different ranges. My CYCO Coco pre-mix was ph buffered. The De-Gnat agent that goes over the coco for mite protection maybe causing.

Whats going on?
So.. 6th week into it. My leaves have various brown spots and yellowing spots in no particular spot. There is some browning on leaf edges. Also tips are up. I am thinking cal mag and to much heat. But not sure. I lifted light up and so far nothing. Also started adding cal mag .

Should I use a pH up -product?
After mixing nutrients with my tap water, the pH of the mix is around 5.5. Should I use a pH -up product? Plant is showing a slight nitrogen deficiency. My tap water base pH is almost 8.0, but the Biobizz nutrients bring it way down. I am using 50% of the recommended dosage.

Ec rising in hydro (6th week flowering - closed circuit tank and drip)
At the end of every day, EC rises by 0.2 at least. Starts at 1.60 and then in their evening it goes up to 1.83 ! So I have to add water (2L) in order to go down. Does it have to do with the fact they had overfeeding, toxicities and deficiency so they don't feed well ?
