Does the new growth look good? Is the yellowing and screwed up leaves just the bottom ones? Judging from the pics that looks to be the case.

The yellow leaves of a nitrogen deficiency may show signs of brown, and they will usually become soft and sort of "fold" in, before possibly turning crispy but ultimately falling off on their own. If the yellowing leaves are at the top of your plant or the yellow leaves are mostly new growth, then you probably don't have a nitrogen deficiency. Nitrogen deficiencies always affect the oldest, lowest leaves first. If new leaves aren't getting enough nitrogen, the plant will start to "steal" nitrogen from the older, lower leaves, so that it can give it to newer leaves. This is what causes the yellowing and wilting of a nitrogen deficiency.
It's relatively normal for your cannabis plant's leaves to start turning yellow towards the end of your flowering cycle as the plant becomes nitrogen deficient while creating buds.
However, if your cannabis plant is losing lower leaves fast due to yellowing (if yellowing and dying leaves is "climbing" up the plant from the bottom), especially in the vegetative stage before plant is making buds, you have a problem that you will need to fix as soon as possible. Got this info from grow weed easy check it out. Also have you checked for pests ? What are your temps, and humidity looking like ? Whats the size of the pot the sickly ones are in?

Calcium deficiency look it up

I always use cal mag, meta-k, microblast together immediately if I see anything off like this. Those 3 will solve 90%( slightly exagerated) of your deficiency issues.

Yes, any hydro store and most garden centers carry them.
Well I don't think I'm going to use Coco anymore I might go with ffof least I don't have too feed for first few weeks I need dirt I can use the hole grow and just add water but that's not going to happen.Does or would Cal mag go bad I have 2 diff brands and they don't seem to be working been using it a long time just not sure it's working like it should

Your not really going good to "see" some huge difference running cal mag. You just won't have a calcium or magnesium deficiency. If your plant is still have issues then its likely a deficiency of something else. That would be best addressed by microblast or another micronutrient supplement. Coco is similar to running hydro. You have to supplement everything a good soil should have.
