hi peeps i know what your thinking more of the same

but i have been reading up before i posted and just wanted some confarmation. i got a few of the bottom leaves starting to yellow and the rest of the plant is healthy. they are 23 days into flower and ive only been feeding them bloom ferts entill i read that it could be that i need to add some grow fert with the bloom, which i did and this was 4 days ago but when i checked them today these yellowing leaves had falling off is this right?
strain-Gigabud
23 days into flower
grown in soil (not sure what will take a gander in morning)
under 250w hps
been feeding her 5ml per ltr of hesi bloom for a couple of weeks but this week also added 1ml per ltr of hesi grow and reduced the bloom to 3ml per ltr



any input would be great thanks
peace
