Hello,
It looks like the beginning of the need for a calmag supplement...the striping on the leaves always makes me think of magnesium deficiency, it usually has that interveinal coloring.
I used to think i never needed a calmag supplement because I used tap water and it's already in there...but once i started using it in my lineup things were much better.
Good luck with the grow ✌️

This is definitely due lack of calcium or magnesium in the soil. You usually see this when people use R/O water since its stripped of all nutrients. Easy fix though you just need to add Cal-Mag to your feeding regiment before it gets out of hand. Good luck with the rest of your grow growmie and any time you need help or advice don't hesitate to contact me via PM, I'm always down to help

Yellowing on lower, older leaves. Starts with crispy tip, curling downwards then slowly progress to the whole leaf. The leaves haven't started falling off yet but I feel if it doesn't get resolved soon then this will be the next step. Thanks for the help.Week 6

Apricot Oreoz... the Unhealthy RuntDoes anyone have any experience with growing Anesia's Apricot Oreoz seeds? The plant seems to be experiencing a Cal-Mag related nutrient deficiency that the others are not. All plants are being grown under the same conditions. Any suggestions?

PH Fluctuations and/or Nutrient Issues?I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?

Yellow and skinny growth?Can anyone tell me whats going wrong here? I'm guessing the tips yellowing is nutrient burn from the MG soil. But the allover yellowing between the veins and skinny growth has me stumped. My first grow did something similar going into flower. I appreciate any tips or suggestions.Week 5
