so I'm running 8 plants all on an auto pot system and 100ltr tank, 2 sun system 1850 720w led fixtures, using the canna nutrient line and the canna boost, I'm currently on day 19 of flower and I am noticing a lot of the lower growth seems to be dying very very early and quickly the edges of the leaves are turning brown and then it spreads inwards until basically the leaf is dead and it'd also effecting some small lower bud sights, I've a good reason to believe this isn't being caused from light stress as the canopy isn't showing any light/heat stress, my room is at a constant 23° celsius as of the climate controller that is running my intake,exaust and also 2 large floor fans, and then there is 2 large wall fans constantly on with a c02 bucket under each fan being distributed from the fan as the lines are attached into the blowing direction of the fans, the 2 floor fans only come with the exaust and the a/c which keep the room at a constant temp humidity is currently at 55% RH and is also being controlled with a humidity controller that is attached to a humidifier and dehumidifier to keep that perfect, so I have tried to cover all I can think of in regards to info about my grow, only thing I forgot is I grow in canna professional plus soil with added 30% perlite I use 2 inches of clay pebbles at the bottom of each of my 25ltr 5(gallon) pots to help with drainage and uptake recommended by auto-pot themselves and my pH is always bang on in-between 5.8-6.2 like to have it at 6 mostly, on the start of week 2 I started adding rock resinator to my other nutrients at a dosage of 1ml per ltr which is the low dosage recommended for average level feeding, if you need any other info gimme a comment, thanks very much for your time, I just wanna get this sorted before it can't be sorted, thanks
