It's normal for some of the bottom leaves to yellow and die.Get rid of them and give them some cal mag and bloom nutes.

Ok thanks I was under the impression it's not good to remove them? I guess they gonna die anyway lol. I will continue on for the remaining couple of weeks nutes, see what happens! Lol

Ok so I continued feeding at 1/4 the nute strength along with some Epsom salts, I came in this morning ( about 12 hours or so after feeding ) and another plants main older fan leaves have turned pure yellow with a brown crust all over, bit like its been dried by the sun. Defo not a heat or light issue. Must be something to do with feeding? I still suspect a mag deficiency from what I have read... I am using Canna Boost and this is supposed to cause the plant to increase its processes and metabolism. I am wondering that maybe by adding this has caused it to want more mag and it's just not there as I have been using mainly filtered water. Never again lol. Any suggestions welcome please peeps!
Thanks

Ok Guys, an update. After all this time I now know the problem for definite. It's those little fungas gnat fuckers... I noticed some a week ago and put some extra traps up and thought there wasn't enough to do harm. Well...... Walked in my room today and my fly strips are literally covered and some yellow sticky pads on the tent sides are also covered enough to make some gnat pies :no:
I then read up what the larvae do to the plants.. Said yellowing of random leaves.. Necrosis patches etc... That is EXACTLY what is in those pics... Now.. I have been only watering once they are dry but these little shites dont seem bothered. So I went and got some sharp sand but am reluctant to put it on tbh.. I'm now trying to source some hydrogen peroxide as this kills them outright. But not so easy to find here in the UK and for 6 litres, at 1:4 water, im gonna need a bit.. If anyone knows the exact amount I should use then please let me know.. Please give me some suggestions guys.. Thanks.

Day 61... I think three of these are maturing?
So the necrosis in the leaves has stopped, I put sand on top of the soils in the end... but now the main fan leaves on 3 of the girls have all started to yellow but there is no necrosis going on now...just ya normally yellowing leaves although in one plant half a leaf has gone a redish colour lol.
I gave them one last feed of pk13/14 and am now going to flush them for the next couple of weeks. I think one of them was rdy a good week ago tbh, all her orange hairs have coiled back in on themselves and she seems to be 'losing' the smell she had before....but im sure it will still get me stoned lol. They all have to be Cut at the same time and 3 of them just aint quite done yet so going to leave them till the flush cycle is over in about week and half or so and hope for the best that the ones that seem 'ready' will be ok.... Wont have a massive harvest that's for sure but will look forward to what I do get
