RQS Critical Feminized

Hi, i'm having a problem with my plant.
It's been more than two months and she never looked healthy.
She's inside a tent 60x60
Led 130w real, but i cant put full output or she'll burn.
3 lil fans inside with an enstractor on the top.
soil biobiz light mix
i'v given her different nuts to try to keep her up, now i'm giving only water.
What's her problem? i'm very tempted to trash her and plant a simple autoflowering seed that i have.
since a couple of days i switched to 12\12 to try and see if she flowers.

a bit over-fertilized, but not sure if n or p or k
add some epsom salt for mg
but mainly thrips
chose your weapon

i have epsom salt, i'll give some tonight
thrips the insects? i didnt see any movement around and inside the growbox. it seems wierd.

 

[handwerker]

they are kinda small hoppers and you will not really see them flying around

Thrips - Wikipedia

en.wikipedia.org

they eat leafes, shit on them and are laying eggs
i can see a lot of leaf damage and some of these fuckers on your pictures
i like stuff based on Pyrethrum against them but they can get resistant so often nematodes is the way

 

[stizzo]

Epsom on the plant or in the soil?
Plus the Pyrethrum i bought has to be diluted in water. Should i use aways ph correction in it or just tap water is fine ?

The plant is starting to exhibit magnesium deficiency.

The problem is the Biobizz Light Mix.

Light Mix is great to use as a base for supersoil. However if you want to grow in it, you have to at least add a tablespoon of Magnesium Lime or Maerl, just to get the pH higher. Light Mix on it's own doesn't have enough nutrients and a pH that is too low.

Personally I'm only using compost, or supersoil, or biocanna bio terra which is mainly composted treebark.

A start is to feed them with a higher pH, starting with 7.5 and over the next grows get down to 7.0. They also need more nitrogen, N and Mg are synergistic and help in eachother's uptake, which will also prevent this magnesium deficiency.

Low pH locks out mobile nutrients - N, P, K and Mg.

Bio biz light mix needs a steady supply of nutrients. If you use this soil mix you need to start your low ppm feedings with every watering.
