Sir,
It appears the plant is overloaded with water, due more to newt lock-up,
flush feed with 300 ppm @ a 1/3 of regular feeding program with drainage of one gallon.
no water till it drys out and ppm ph temp check your solution. Remember less is better....
molasass is good i use 1/2 cup per 40gal benifits 401k
light equals mass so upgrade in lighting would benefit,
plant needs to perspire add air quality to environment,

but all in all not to bad can bounce back quickly if you put all elements in order,
air light temp newts.....


0-0-0 soil sunshine#4 best to control feeding elements,
with amendments of perilite and vermiculite.
hope it helps.
