I think this is problem with coco buffer. Try to use more cal-mag and change your nutrient solution. Lower potassium, raise cal-mag. Problems with coco pH - always about wrong watering and wrong composition of the nutrient solution. p.s 5.8 pH its not bad for vegetation.

You are spot on. Coco range 5.5 to 6.5. You couldn't be any better. Your run off is smack bang in the sweat spot at 5.8 and 5.9

Starting to yellow So I had good growth up until 2 days ago when the one plant started to yellow. I had them going 24 hours a day and I got grow dots mixed in the bottom two thirds of the pots. Could this be light stress? or could it be hungry?

Nitrogen deficiency or could it be nothing In the pictures you see some yellowing and small spots. I don't know if it's Nitrogen deficiency or not because it stays with those two leafs.

Leaf Issues Hey all, my almost 5 week old Moby dick auto flower is starting to show some issues in the first week of flower. She got a dose of Veggie nutes 5 days ago, and a little bit of Bloom yesterday trying to fix it. Temps have been high and humidity low, would that cause this?

Yellow on leaves Day 13 leaves started to look yellow / dull on tips hasn't seemed to improve 2 days later, it is the auto soil premix I'm guessing the roots are getting close the soil and nutes kicking in or does this look like another issue?

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?
