It’s hard to tell from the pictures. But I’d start by checking (and double checking) your PH. I’d check the PH of the runoff and go from there. If it’s not a PH issue you’ll know it’s a deficiency and can make a better diagnosis.

My plant has got some Problems. The top leaves are getting black tips and fingers start to get thin and wrinkly. My thoughts were it could be too much humidity, phosphorus deficiency or some kind of pests Does anybody know what the problem could be? I'm thankful for any advice!

Crispy leaves?Crispy leaves developing as it flowers. Seems to just be those that had some spots from what appeared to be a magnesium deficiency. I hit it with cal-mag and the spots stopped but recently the most affected leaves are shrivelled. Only maybe 4-6 leaves right now.Cheese Auto Fem Canuk Seed Outdoor Grow

To remove or not to removeSooo, 10wks she is looking strong. Do I remove some of the bigger leaves that are almost 6-7 inches long or do i wait. Should I switch to other nutrients now or I have tiger bloom, open sesame, beastie bloomz and cha ching. I don't understand the feeding cycle it confuses me.Blueberry feminized.

Overfeeding protocols lolOverfed a couple hundred mls last feeding 2 days ago and the soil is still saturated. The plants leaves are wider and almost a neon green...it's not wilting or drooping. But for further reference on what to do in this situation. Thought I took a pic but I'm at work right now.
