Plant deficiency or something else

[BigB6]

Problem: deficiencies or something else?

Medium/grow method: plagron terra soil hand watering

Feed: and supplements used: advanced nutrients sensi bloom a&b 1mil/litre, b52 1mil/l, voodoo juice 1 mil/l

water source: tap/drinkable

Strain/age: fastbuds orange sherbet day 21

light used: lumatek attis 300w

Climate: 26 degrees Celsius 70-80% humidity

Additional info: This started around day 16. I was only feeding water up to then until I saw this and thought it was k deficient. Which is why I started feeding. It doesn't seem to be getting any better. It's been 4 days since it began should it take longer. Any idea, it's only happening to the orange sherbet plants. Whatever it is it doesn't seem to be slowing growth except for a couple.

I cant say much but the 2nd pic looks like potassium deficiency and the first looks like it has nitrogen toxicity. It could be something completely different. Humidity might be getting closer to the high end too, too much humidity will really slow a plants ability to uptake water.

when did u start feeding? Your soil is pre-fertilized, so I doubt a def. Especially if you were adding Nutes to a charged soil this early. Possible lockout?

Looks like too much N-P&K to me. Well too much everything.
