Hi all. One of my plants have yellow tips at new grow. Problem start with yellow tips after that two rusty dots at the end of the tips and then tips burn. I grow in coco hempy with perlite on rez. Coco is canna coco. I feed with coco a&b 2 ml/ltr. Also add sensi cal mag extra 2 ml/ltr. Tap water 150 ppm. Feed with 1.4 e.c 700 ppm.

Tip burn is typically a sign I am too hot on the nutes and more specifically Nitrogen. Rust spots make me think Ca defeciency but I would like to see a photo. I need to know a lot more before I can really be helpful though.

Switch your calmag to epsom salts. Do a fush 3× gl size. Administer enzymes and bennies.
