Weed plants need help??????

i have 2 plants that are showing signs of something,
the problem is with my larger plants, I have flushed one of them and the got ionic nutes for them,
the one i did not flush the tips on the plants are turning brown as seen in pics
and the larger fan leaves at the bottom are 30percent yellow, both plants have this problem,
any idea's lads

my first guess would be potassium deficiency--thats just first impressions

but, you should post more information such as:
temps
humidity
nutes used
feeding schedule
and any other things that may be relevent

then maybe some people could help you out a bit easier

Could be tons of stuff..... like Zee Said give more info. Might even be over fertilizing.

I am giving it nutes that are called ionic, there is 3 bottles of nutes A,B, and one for the boost, 3.5ml of each a an b and 1ml of bottle 3 called boost per liter, only watering when pots are light, I have all so got a small bottle of super drive witch i give them 1ml each week to help with the yellowing in the leaves, The temp is 76/78 deg

either nute burn or a ph issue! try flushing them with water and check your ph.
