Hey guys/girls
I got a problem with 1 of my plants & i could really do with some outside diagnosis.
First off they are all BD x bubblious clones 3 weeks old today. They are in a biobucket system being fed dutchmaster nutes. the PPM is at 1030 & PH is 5.8, water temp 23c. Room peak temp 33c, 'night time' temps drop to round 19c. They are growing under 4 x 600W HPS mounted in cooltubes fitted into adjusta shades. Each bucket has its own air stones as well as a water fall effect into the res that is supposed to supply all the needed air without the extra air stones but i just can't bring myself to trust the waterfall effect on its own. lol.
The root system on the sick lookin plant looks healthy, its nice n white, no brown or disclour & is only slightly less advanced than the others. The first 2 pics are of a couple of healthy plants. the last 2 are of the sick 1. I'm sure u can see how much stunted it is compared to the others as well as the really droopy leaves. Its been this way for the last week & a bit, just seemed to stall for no reason i can find. They were rooted in small rockwool cubes, at first i thought that maybe the cubes were sitting too close to the water & so were too wet - they did feel pretty damn wet, all of them tho. So i raised all the net post by about 1.5cm about 5 days ago with no effect. They are all in the same system & in the same medium - lava rocks.
Today i am supposed to increase the PPM level to round 1400 (DM nute recomendations) but i'm holding off for now till i get this plant sorted.
I'm sure someone is gonna suggest lack of air - that was my thought too so i turned the air pump off for 48 hrs to see if i could make it worse but to no effect at all. the pump is back on now.
A little bit more info. The sick plant is VERY wobbly in the net pot. I was thinking it might be stem rot from the rockwool being too wet. As i mentioned before i had raised all the net pots by the height of some 13mm polly pipe. I just replaced the polly on the sick plant with some of my 32mm drain hose so now its much higher out of the water. I've also removed all the RW i can get to without disturbing the lava rocks too much, prob at least half of the cube - the top half that is.
