Need some help, I'm really lost
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?

Dark tips
it seems to me that the tips of the leaves have a very dark color, it looks like an excess of nitrogen but in three weeks I have never fertilized and the only additions to my biobizz light mix are a sprinkling of guano kalong and 10% of worm humus biobizz.

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.
Is this a deficiency or some other kind of issue? Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.

I’ve never seen this before?!
Weird spots on leaf’s I’ve never seen before. Growing in coco with dry amendments and worm castings. Ph 6.7/6.5. Just gave some compost tea earlier today. And earlier this week some GH calmag because some of them are showing deficiencies for that. But what are these weird spots?

Brown/Grey spots on the leaves
Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

Yellowing to slight grey leaves
What's the cause of the older yellowing leaves with some grey and the slow spread to the newer growth? I'm between pH problems and or deficiency but not too sure.

My seedling doesn't look so good.
This is my first coco grow so could be possible that I made a mistake. The other three seedlings are super healthy but this one has this weird thing with it's leaves. Somebody seen this before? I gave them some root juice and fertilizer before transplanting with ph between 5,5-6.
