Hi all
I’m 3.5 weeks in flower. Soil .
I feed once a week at 1/2 strength.
Some of leaves are going yellow around the edges? A very light almost neon yellow .
is it lack of N ? I’m feeding bio bizz bloom and heaven , 1ml per L of water .
I have some magic green foliar spray but not used yet. Can you use that ok flowering plants ?
Thx for the help !

How big is the pot they're in and how long has the plant been in it altogether ? Looks like nute burn. If it's a lack of N you'd see lower leaves very yellow and falling off. Too much and they go dark green and form claw shapes.

is that a sodium light there under? the lights making the leaves an orange colour and we need to see the plant under camera flash or daylight to be sure of the problem

Yes, it’s under HPS . Sorry, that’s all I got for now. It’s like a neon yellow .
I need to do my EC readings later etc

So yeah this where my girls last night checked on my tent and my GDP is looking like straight trash seeing what some of of y’all think this is and why no one else in the tent is having these issues. From about a month old I could tell is was off it simply in every aspect of the word not developed as the other sisters ,stalk of the plant is young and not hardened like the stalks and branches of my others ,even leaf size has never matured in my opinion. It’s like a premature thing unable to support itself .

Not under or over watered .

It looks like nute burn but doesnt sound like nute burn ...its one leaf wouldnt do anything about it. Probably under fed be on the look out for mag and K deficiency's

No you shouldnt foliar spray in week three of flower. Not saying you cant or you cant spray anything after week two but all that should be taken care of in veg through week 2 of flower. Foliar feeding is a skill and you should practice on one plant if you want to do that. You cant learn if you dont fail. You shouldn't folair feed a sick plant a hot mix ...that magic green should be about 500 ppm or so on a healthy plant 200 on one that is sick ...to be safe... and you have to do it for awhile to get good results it isnt a one time spray and done thing. imo. Ive had the same magic green bottle for ten years... part of learning about foliar feeding is that after you know how to grow a healthy plant is that you dont need to foliar feed anything.
