Looks like a cal/mag issue starting up or PH is imbalanced causing a lock up.

Hi people, need some serious help here. The new leaves look like sh¡T. They are kinda yellowish and the tops are necrosed. Some spots on the leaves too! I added some silica in the last water but I don't know if was the cause. Soil pH varies between 6.5 and 7.0. Any ideas?

CalMag or something else?
Discolored leaves at the bottom of a 3 week young auto flower, full feeding schedule in diary. Was thinking Cal-mag deficiency, but after 4 days of running 2mL/L Cal-mag supplements it's still getting worse. Could it be lack of phosphor, and will BioBizz FishMix/Grow be enough?

YELLOWING IN DWC!
Recently a friend transplanted his Northern lights auto into a DWC set up, since then the plant has suffered severe yellowing and stunted growth. His nute feeds are optimal just as they were in his coco format and his PPM keeps decreasing. Any ideas?

Leaves curl, become crispy and have weird colors
I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

Seedling advice
Hi, my light was at 60cm with an average humidity of 70 degrees Celsius. There’s slight dryness around the tips, yellowing, crispness. Remedy thus far: I moved the light up to about 75 cm, it’s a 100W led. Humidity also dropped to about 60 degrees. Any advice to remedy?

Problem with plants in the 3rd week of vegetation.
I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.
