Leaves turning purple please help

**Crunchyleaf93** · 05-09-17, 08:11 PM

Hi guys
Noticed these weird purple/brown spots on my leaves a few days back, i put it down as nute burn and flushed them and trimmed off the damaged leaves. It has gotten worse since though and started appearing on more leaves im kinda lost now not sure what to do. Please help

Im growing in coco under a 600w vipar LED light, Ph is 5.8 and ive been feeding them at 0.9-0.95 ec every few days using canna coco A+B. Temps are around 25c when lights on and 21-23c when off but i have had a few days when it dropped to 21c when lights where on but i corrected this as soon as i noticed. Pics are attached. If you need any more info just ask.
Thanks

You should be feeding/watering everyday in coco...

Okay i will do from now on, do you think this is why the leaves are doing what there doing?

Would you feed them everyday even when they are very young or do you wait until they are a couple weeks old before you start watering/feeding everyday?
