Hi guys i dont know whats happened but the lower leaves av started turning yellow on tips but only on the one side of plant n at bottom. Any ideas ??? I was thinking is it because of the feed being raised too high. Im really baffled tbh

Looks like the start of nutrient burn. 

From what I've learnt in soil, you'll need to flush (making sure the water is balanced)  and reduce the nutrient dosage when you restart feeding again...

When you upped her nute dose recently did you jump up quite quickly? as in if you were at 150ec and then jumped to 490-500ec without stepping the increase it could just be the shock of going from a lower to higher dose. I usually gradually increase the dose over a week, it helps them adjust to the stronger nutrient dose, but a little bit of tip burn isn't that concerning, only if it starts to really creep or you see it on majority of those leaves. For instance and this is my way of doing it I'm not saying its the right way but it works for me, I will gradually bring the dose up until it hits my target or I start seeing tip burn occurring, if I don't get burn she stays at that dose, if I'm getting a bit of burn I will dial it back a bit and slowly increase as she gets bigger.
