answered grow question 6y ago
Hi Mate, It seems to me an initial K deficiency. Also I have noticed the edges of the serrated leaves begin to curl up as heat/overwater stress. I think that only little corrections are needed, she is quite healthy. IMO 🤞

Is she a write-off?
Hey guys, my GSC seedling is about a week old. She had some problems getting rid of her seed head, and I managed to fully remove the seed coating and membrane just over 24hrs ago. Is she a write-off? It’s not looking too good

Leaf discoloration
There is a purple/blue tint to the tips of my older leaves. New growth coming in lighter green. Slightly red and purples stems only at base of oldest leaves. Leaves also taco curling slightly. Thinking phosphorous deficiency at this point, maybe combination N toxicity and heat?

Hello fellow growers, I noticed some large brown spotting on several of the leaves toward the bottom 1/3rd of the plant. They could be a result of sloppy watering, but I'm not really sure. Any diagnosis would be appreciated. Thanks! 😅

Deficiency ? Chlorine from tape water ?
Spots appeared after last watering, 4 days ago. It doesn't seems to evolve to more spots. Using basic gardening soil. Chlorine in tape water X 4 those days, because of covid-19. So if not a deficiency, might be Chlorine ? Or Chlorine killing life on the soil? Suggestions ? Help!

Drooping leaves
Firstly I would like to thank those that helped with my last question, I'm unsure of how to reply but very grateful 😊 Throughout the grow these girls have been drooping at the end of each day, 3-4 hours each day, is this normal? Should I cut down how much light they get? Tia

VPD related leaf issue? Brown spots, don't think its Cal related. Pls, any help would be appreicated.
Brown spots on leaves, I thought it was Cal related, and tried different doses, with no success. Could it be VPD related? It can and does get very hot and very humid in the 1.5ftx2.5ft closet. Even when running no humidifier (Live in AZ). I've been struggling with this for months
