checkout my superlemon haze and 3 blueberry flowering, any advice plz

hi thats my lady, they have been in flowering for nearly 5 weeks, on the superlemon haze some of the oldest leaves seems to be turning yellow and the wains look yellow and the leafs looks as if they are rownded up, cant tell most of that from the pics though, i think its magnesium defincy so i gave them some extra nutes and ill check the ph tomorow, done some research and it points out to be a magnesium deficincy, but i think superlemon haze is more hungry plant so it might just be that it needed more food, ill wait n see, any advice plz

Overwatering should be your first suspicion, back off on the water for a day or two if the symptoms increase it is most likely a deficiency.

During flowering the fan leaves will yellow,

Bottom leaves will go first I would not worry about it. You are allready 5 weeks into flowering just let them finish. When I grew that strain she took allot of nutrients and was happy. Keep what you are doing just dont over water and start your flush 2 weeks befrore you harvest.

I water them when the top soil is dry to touch, every 3rd or 4th day and I give them about 6 litre, water until it starts driping out from the bottom of the containers, but when I water them the soil stays for about 4 days is that acceptable or do u think the rites need oxygen more often, do u think I should water less than I do or is that acceptable, thanks for ur advice
