Day 14 browning on edge of one leave and yellow spots

[ibz]

When I talk about salt it's surprising how quick it can build up. In the following photo all the white under the right leave is salty on the coco fiber from my nutes.

Once a seedling is tall enough I like to add clay pebbles to keep the coco from drying out and add air.

Now you mention that I have been wondering what the white stuff is on the surface of my coco! So that means there was definitely a salt build up!

Don't know if you can see the traces of white bits in this picture from today may need to zoom in

IBZ- this pic might be the answer to those funky leaves and white 'fuzzy" stuff-->

---> See the blackened tissue with the white fuzz? That's a fungus, likely botrytis that's infected her,... hence the funky symptoms! I see no Ca defc. here, though the advise given about it is solid,... coco has odd CEC characteristics, and a particular penchant for Ca, and to a lesser degree, Mg,... it will hog free ions until sated, then it'll release and bind more freely,... Are you new to coco? there's a lot to learn about this medium, veru different from other soilless mediums and nothing like soil at all!...easily the [HASHTAG]#1[/HASHTAG] issue with new coco growers coming here,..stemming back to treating coco like soil! .... I can't see the white bits you refer to, but I have doubts that you're getting heavy nute salt deposits this early, which looks exactly like frost on the surface, not fuzzy or micro-fiberous (fungal hyphae)....
Pure Neem oil is great for this, and will help boost the plants immue system,... also, start using a SI supplement regularly, for best effect,... several key benefits to it, and it can help raise pH a bit as well, if that's of an advantage to you,...

Well growth is great after watering to run off the girls have been loving it
My strain is HBSS usually a tall strain but I'm on day 24 and she's short and bushy so I don't know what I can do about that I have been LSTing aswell

What do you think guys?

Looking real good now, I wouldn't worry too much about her not being tall when she starts to spread she may take off on you.
