Soil or hydro or coco: Coco hempy,perlite only in the res

Strain:OG Kush/AK420

Photo or Auto:Auto

plant age:6weeks ish

pot size:11ltr

has it been repotted? and when?:Nope

soil type:N/A

nutes or additives used and how often for soil:N/A

Air temps (max min):77-80

Res temps (max min):N/A

humidity:45-55

lighting type and wattage (hps, led, cfl):2x240w QB's 3500k

Light schedule:24hours

ph level:5.8-6 tried 6.2 as well

EC (hydro and coco only)?

Background EC.?

feed schedule and nutes (for hydro and coco)2.5ml micro,2.5ml bloom,.75ml grow,5ml koolbloom,5ml terpinator per gallon per day

I'm getting this shit again lol,I was feeding 2.5ml calmag/gallon but stopped incase it is causing my problem here,the plants otherwise look healthy and it only seems to be affecting my largest AK420 auto,and my OG kush auto but I do see some signs on my banana blaze auto as well.
Lights are running at 220w each,about 18" from the plant tops,I have been using the feed chart below just like I did with my coco/fabric pot grows,always feed each day with plenty of runoff,I have considered running the lights 20/4 but I am highly doubtful that this would help.
Every 2nd day I give the girls a light spray with optic foliar overgrow.

You think that I should increase the liquid koolbloom per gallon to 7.5ml bud?

Hi Scootb,

I had to print screen to show you this chart so it's a bit fuzzy but you might be able to google to see it properly (no links)

This chart differs from ratios in the one you are using and says you should be feeding more of the grow rather than the micro.

Maybe this is reason?

Also says 18/6 light schedule throughout the grow.

This might be a little clearer

Doesn't seem much of a difference to be an issue though,I will give a try though as you never know.

Someone here said increase the pk so that could be an option too?
Good luck mate
