Hi mate, believe this is caused by PH issues. Makes it look like a calcium deficiency but its a slight lock out... Just keep an eye on your PH and do a slurry test of your soil to see if she is too acidic or not...Good luck and happy growing

Discolouration of some leavesIs the colouration of these leaves someone to worry about? She’s a young, 2 week old Wedding Cheesecake auto and I’m new to growing and just want to make sure she’s ok! She’s growing in a 70/30 split of coco and soil and has only been fed water so far! Is it nute time?Leaves. Color - Yellow

I think I have nut issues?OK here's today's update, 3/9/22. They are all doing great, they're all standing proud now! I think they needed to dry out a little, more light and needed the extra nuts. What do any of you guys think could've caused these symptoms that my girls are/have shown?4y ago

Leaf damage/discolourationThe yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?4y ago
