Deficiency ?

[Mario]

Medium/grow method: Soil, BioBizz light mix, 7.5 liter pot

Feed: and supplements used: Bio bloom, Bio grow, DIY calmag

Water source: Tap water

Strain/age: Northern Light, 40 days old

Light used: 300w Meizhi LED, 40 cm from plant, 20/4 light schedule
Climate: 23-27C

Yesterday watered with 3ml/l bloom, 3ml/l grow, 2.5ml/l calmag. Also a few days ago had to put her in a garage of 17C for like 10 hours, could temps that low have triggered some def ? What is wrong with my plant ?

It's normal for older bottom leaves to yellow so not to worry.I would just use bloom nutes at this point and skip the veg nutes Are you following the dosage given by Bio Biz?Are you PH'ing your water? I would raise your light up slightly to 18 to 20 inches

I am following this BioBizz Light Mix schedule - http://greenbookpages.com/wp-content/uploads/2014/07/BioBizzfeedchart1.jpg
PH my water to 6.3, I know I dont have to bcz its organic soil but I still do it.
I dont really care about the old leaves yellowing, what worries me are the newer top leaves that have this kind of yellowing going on in between the veins. They just look a bit sick to me, like they have some kind of deficiency or something. Idk maybe I am just overthinking

I would still raise your light up slightly led lights can cause problems if there to close.Other than that she looks good.

--- the cool spell may have triggered some of this,. uptake and transport really bog down when that cool,... not bad, might be partly a plain lack-of too, as Biobizz is pretty mild stuff,...
symptoms look like a little P and Mg defc.; keep the temps warmer if you can, and if so, increase your feeds another ml or 2,.... Light should be about 20" from tops,....
