Flowering n bottom leafs drooping???

Hi just wondering if this is ova watering or something more sinister?
Cheers guys :

Looks like nitrogen def IMO and not enough light...

Don't think its N diff I've been adding N to water last couple of weeks when I had a serious N problem ( reason bottom leafs look yellow)
Just seems strange just the bottom leafs I thought it might b ova watering or the fact its in flower, I heard lower leafs can die when in flower or a mag diff ????

you should not lose that many leaves. Could be a mag def also.

Cool I've got some Epsom salts but don't no how to mix it up too a litre water can only find to the gallon

the droopsies can be from under or overwatering...all tied to root suffocation...too much water = roots submerged too much and no oxygen getting to them...not enough water = root system drying out too much causing them to not get any oxygen either as its not pulled from "air" but pulled from the water, but too much is well...too much

Cheers massah I thought it more likly Ill leave the watering a couple of days n give it a go then with some added mag just to make sure
