Looks like possibly some wind burned tips from being close to that fan. Or from rubbing on your tent sides? Or just some nutrient burn. I'd not worry about it much unless it's happening to new growth. 🤘😤

K deficiency? Hard to believe that can happen in 65-gallon pots.Are getting big though.New growth tips looked yellow,hit them with water-soluble K and the new growth edges seemed get green.Some toco-ing, humidity is kinda high. Too intense light(800 ppfd), not enough C02 maybe?

Nute Burn Plan. Lower light to 24 inches and turn on bloom switch. Flush soil with 8 litres of water (PH 6.5) per pot. Questions: will increasing the intensity of light increase plants ability to absorb nutrients, or simply stress them more? Is 8L water/ 10L pot enough to flush?

Leaf damage and flower analysis
Asking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower

First, the lower leaves started turning yellow much quicker than usual during flower. I didn't change any Nute levels in my water because I wanted to see how things went. Then we had a few really hot days then this started happening to the leaves. more detail in week 17

Problem with front middle purple punch. Info provided(See description for more); Temp: 71-79.5F, RH: 46.1, DLI: 40-50(decreased today due to tacoing)
This is an organic grow using Coast of Maine Organic plant food, and lobster meal. It appears to me that the plant has deficiencies for all the three major nutrients, or lockout, but today it is also showing what appears to be Calcium or Magnesium. I've been using castings too.

Biological Cal/Mag alternative? It appears the cal/mag from BAC is mineral feeding, is that correct?
Starting to see what looks like a deficiency of Cal/Mag. I'm trying completely biological and I can see the Cal/Mag under the mineral nutrients tab from B.A.C. Is there a biological alternative?
