So I have a question about maybe a deficiency???
I'm at day 52 ak47 autos. Temps 70s humidity 55 RH. 3 gal pots ~650 PPFD (~ 16" above canopy) on average for lighting. Tap water 265 ppm pH ~6.5. promix peat mix.
I did get a bit of nute burn 2.5 weeks ago (Mega crop 1 part 4g/gal recommended strength which I had slowly built up to step wise) so 2.5 weeks ago I fed straight water no nutes. 3L 1x a week now wait till 3Gal grow bags are light but not dead dry.
Last Sunday I noticed this... Bottom leaves only.

Sunday I watered with Mega Crop 1 part (3/4 strength 3g/gal & MC sweet candy g/gal). Today I see this which is new since Sunday (again older bottom leaves)..
