What is causing my leaves to turn dark and dry?
I'm growing 3 Gelato #33 plants in a DWC 5 G bucket setup. Same conditions for all 3 plants, but one of them is experiencing dark spots on the leaves and now they are beginning to shrivel up and dry out. The newer growth looks okay, but might not last long. What can I do ?

Brown spots on bud site leaves?!
halfway through flower and now in week 6 flower one of my plants is showing some large brown spots on only the upper leaves. I’m not sure if it’s a light or ph issue as the light is close. I stopped cal mag and some nitrogen this week but spots were showing up before.

Leaves keep turning brown and yellow
It all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it. My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead. What do you recon, why could it keep getting worse?

When should I put the pellet in the 5 gal pot??
I am currently growing a tangie'matic with "a pot for pot" grow kit. At first the seed germinates in a pellet. Then it says "put pellet in 5 gal soil mix after 10 days or when the third set of leaves matches the second." I did it after 10 days and this happened.

Brown spot on leaves
I'm experincing a bad situation. Leaves are becoming brown in the margins and I can't understant exactly the cause. Probably there are more causes, some phosphorus deficiency caused by low temperature but I'm not sure that's the only diagnosis. Someone could help me?

I transplanted these girls 2 days ago and have started them on a new nutrition. I’ve noticed some discoloration on one of the leaves today almost sure it’s the nutrients. Can someone help me figure the best thing to feed my plants? Thank you (nutrition diagram on my first diary)

Guess on what this is?
Unsure what this issue might be. PH seems in check going in and out. Getting mainly Fox Farms nutrients - got very weak doses of B-52 and CalMag a week or two ago. The other two plants are fine.
