Honestly I think magnesium is the issue here. If your using calmag increase the dose slightly. Try to go by what the manufacture recommends. If your not using calmag get some and use it 👍 Remos magnifical is brilliant, good luck bro 💪

Crispy Yellow Leaves
Inflow EC=1333 w/ PH=5.8 vs Runoff EC=658 w/ PH=6.0. Insufficient nutes due to light intensity? Perhaps my PH meter is inaccurate? Light is 42 inches from canopy or ~600 PPFD. RH 65%, Temp 80 F.

Yellow leaves
Started seeing new leaves turning yellow at the edges on this BCN Critical Auto. I think it's a calcium deficiency based on my research. Would love to get a second opinion and some tips, if possible. Many thanks.

Is this sight yellowing normal or cause for light concern? No nutrients
Does it look like the new leaves on my 7 day pictures are slightly yellow? Or is that relatively normal with new growth? 20% perlite, 30% coco, 50% organic potting mix. Been really light handed on the water. waiting until soil is completely dry before watering more (1-2 days)

Deficiency?
I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔) The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

Bottom leaves yellowing at beginning of flower
So my plants have been flowering for about a week now and the lower fan leaves are yellowing with brown spots. Should I be feeding them more of the flower girl I’m using or is this a deficiency of a specific nutrient? (following dr earth feeding schedule designed for cannabis)
