have a question... it looks like I am getting signs of phosphorus deficiency... veins collapsing... turning brown.. and really soft leavesthat are dying... only on 2 leaves... could it either be the lights I'm using or ph lockout again? I have been using same water... I have been using fox farms fertilizer at just about half strength according to their "soil schedule" as ive red on other posts... I'm thinking I should stop using fertilizer all together as it messes up the plan every time I use with this soil.or even a weak amount... I haven't phd the water with nutes in it until today, but I have only used twice and only happened after... water was coming out REALLY ACIDIC at first... almost orange... 50% orange.. 50% yellow before it was more toward yellow or yellow green (5.5?) soil has been tested before this problem and was at 6.5 to 7.0 ph it seems it has lowered it a lot (water ph)... I'm going to test it again.. I'm thinking a flush and maybe use 1/4 or less fertilizer if any at all..
