Hello it seems you have calmag deficience. How do you try to correct it. You can use epsom salt which is the best for this. You can mix it in water and mist your plant for a quicker effect. Good luck. Bye

Help diagnose hydroponic plants! Too much light/heat? Nutrient issue?
The plant's leaves on the right are wilting and drying out, while the leaves on the left are spiking. Just did a nutrient/water change but it didn't help, and it looks like growth is being stunted on the right plant. Humidity has been around 45-55 rh and temp 70-80F

Leaf discoloration. 5 weeks old
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)

Nitrogen Deficiency or Nutrient Lockout?
My plants are showing red / purple stems as well as some rust spots in some of the older leaves. Nitrogen deficiency? Or lockout due to too much fertilizer?

Brown spots, serrated edges curling up - calcium deficiency?
This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up. Is this just a straight calcium deficiency?

Leaf spots!
Leaf septoria or nute deficiency? Don't have ability to monitor pH or ppm. Do I cut the affected leaves off or any other home brew solution? 3 different plants in the photos.

It looks like my plant is dieing! Plants turning brown after intense watering period
Did I drown my plant? Stress it? I gave a lot of water in a short duration of time, and now 7 days later she is looking terrible! Read my diary on week 17 for more info!
