Overwater or nutrients?
HeavyHead
started grow question 5y ago
Was away for a week so left my plants on a drip system with fresh water, came back to this. In foxfarm blend of OF/HF. Repotted a couple days before I left on the worst one so possible nutes burn? About to flush and do runoff test.

K deficiency almost wiped out this plant. What do I do now?
I’m somewhere between 2-3 weeks until harvest time should be. It’s day 80 from seed on this autoflower. Had a bad potassium deficiency that I didn’t figure out quite in time and I’m not sure if too much damage has been done. What should I do?

Deficiency or screw up?
What is this? At first I thought it was a phosphorus deficiency so I flushed with extra bloom nutes & overnight the damage doubled. Is it a pest or did I just fuck up bad? She also has seemed to have stopped growing. No noticeable diff in size recently

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 .

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?
Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

N issues
This girl suffered from N deficiency very early. So I gave it nutes. Nutes gave it N toxicity. So I flushed the soil with ph’ed water. You guessed it, it’s lacking N now. The problem is the pot is still very yet and heavy so I don’t know if I should water with nutrients

What does she need?
Without much info except that EC, RH, PH is in a good range: What kind of deficiency would you say is this? Could it be root rot? Could it be PH flux?

PH measuring for Organic Growers
If I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.
