Flush all your plants with a ph of around 5.5 nothing in it just water do this 3/4 times till water till water is running through soil.Looks like you have a potasium def lower feed for a while a week or so use harf strenth but don't start feeding till they have dried through good and propper.Not sure about the one with redish coulour in the leaves the 3rd set of pictures alon bottom left hand corner but givein the plants a flus about every 3 week stops all this shit happening i know its a pain but its well worth it.

thats about the stupidest shit ive read in some time other than the "human shit/piss for nutes" threads here....

A deficiency means that the plant isnt getting enough nutrients to it. Why would someone flush a plant that isnt locked out by too many nutes or ph to get rid of a defficency? That will only make them worse
Never flush a defficent plant unless your having nutrient lock out issues. Just feed it with more of the nutes its defficent in using a ph that is right for the uptake of that nute. Some work better @ different ph's so you should use that ph for a couple days till the plant starts to get better. Then go back to a ph of 6.5-7.0 for soil or 5.5-6.0 for hydro. Dude didnt even know what ph soil plants should be kept @ and your gonna listen to him....Blind leading the blind a lot nowadays I guess.

The last picture is for sure a mag or calcium deficiency IMO. the middle pic looks like a nitrogen Deff to me.

nutrient lock outs usually are caused by a deficiency to start with or a ph problem causing a Deff somehow. What that means is that one nute is so far outta whack that it starts messing with other nutes and the amounts of those that the plant uptakes too.
It can also be caused by high amounts of salts in your medium from too many nutes that the plant is not using as well, but I dont think this is the case here.

You would know because you would have much worse damage than you do actually have.
