Ds' Deficiency Conundrum
I cant decide on which deficiency this is, ive been treating her for magnesium and nitrogen but its not really making a difference.. Maybe shes just super hungry on the N right now during the start of the flowering phase? (is what im leaning towards, she is a big girl)(25inches tall to be exact :thumbs

been treating her for about a week now with epsom foliar feeding three times lightly. for the N has recieved about 3-4ml ofGrowBig within three to four waterings, 4tsp epsom in the soil in those waterings, and 3.5ml of Big bloom within those as well. Has also received about 6-8ml of Cal/Mag solution.

My diagnosis was MAg when i saw the yellowing between the veins
but then i thought maybe the light is too close and was experiencing some bleaching it wa at 17 inches

She is growing rapidly so also i was going back to an N deficiency, i noticed yellow tips on the fan leaves
My Solution: Making a organic tea for tomorrow rich with N and add some Cal/MAg to it as well as 1/2tsp of epsom in a 1.5L feed (enough for a runoff)
also i moved the light up it is currently at 20 inches (noticed the top cola slowed in upward growth and the next branch was protruding the side and tipping the top of the plant in one direction)
Whats your input? Thanks AFN
