Looks like a phosphorus deficiency. I would start by checking your substrate ph first. I just has same issue this last weekend. My ph was crossing to a unsuitable range. Good luck and happy growing 🌱

Necrotic Leaves caused by Calclium defficiencies. Should they be removed or should they be left on. I removed them from my plant. It appears to have been caused by a PH spike while I was away for 2 days. Plant seems to be recovering, but I removed the leaves yesterday. Thanks.

Yellow in the leaves, I've been feeding until runoff on a Sun - Tues - Thurs and just letting it sit in-between. Feeding with a 1.8 EC solution and my runoff starts at 800ppm and then drops down to 500 by the time it's finished. Increase nutes? nutes every day? do nothing?or???

Week 1 Day 5 picture-I'm concerned about the leaves praying to the sun gods and slight yellowing. What's happening here? Is it due to low humidity and possibly light burn. Humidifier has been added to the tent and light distance increase to 20 inches as a precaution 😉

Curious if anyone else has experienced leaves like this on Durban’s. I know I’ve seen leaves like this when temps get cool outdoors but all flower sugar leaves are turning. Watered regularity and fed well in my opinion, so I’m not sure what else it could be. Thanks in advance!

So... the brown spots in the last 2 photos. Are they Ca deficiency? Will I do extra damage if I add Ca/mG supplement? What is the upper concentration of Ca/Mg concentration for cannabis in DWC grow? How can I tell if I add too much Ca/Mg? Help please!
