.....just wait. They arent gonna die over night. If tomorrow is your reg schedule then they will take up the fresh nutes better if you wait till tomorrow.
Exactly.
Along with giving them the fresh nutes i like to foliar feed with a very weak strength nitrogen rich fertilizer if i need to correct a nitro deficiency,foliar feeding gives results very fast & if you didnt wait too long & let the foliage get past the point of no return the foliar spray will green them up much faster than root feeding alone.
If you do foliar feed them just make sure its a weak mixture,this double dosing of fertilizer will not hurt the plants if you dont go nuts on the strength in the foliar spray.
You didnt specify if your plants are in heavy bud or not,if they are in heavy bud you can still foliar feed them,after the plants dry for a few hours put an extr fan blowing directly on the heavy buds to make sure no moisture collects deep in the buds,you do this to guard against bud rott,ive done this many times durring heavy bud with great success.
