Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved.

Need some help, I'm really lostHi 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?

LEAFS DYINGThe edges of the leaves are dry and black. Every single point of the leaf is burnt(black) or yellow...even some edges on the leafs of the coal are burnt. I guess it’s overfert...but I just flushed. Is it Ph? I haven’t checked in awhile. Is it they ready to be cut down?
