Hi every one,
Dont know whats goin on this time round and its doin my nut in! So here goes........
plants are 3/4 weeks old from clone.Pre ph`d rockwool cubes
600wtt HPS-18/6.
NFT,and they`ve been in the system 11 or 12 days. The pump is just a light trickle running only when lights on.
Temps are 81 lights on,not too sure lights off temp,but its in family home....
125mm intake and exhaust rvk`s. On constant.Humidity 40%
On the second day of them being in the system I changed the res and put CANNA Aqua vega in at 280 PPM,everything seemed fine for a few days, just the usual bit of shock or so I thought.Then the smaller clone stared to look sick-drooping leaves,small brown spots then yellowing and dieing. Noticed green slime on the top of the cube,assuming it was just algae,I put a bit of card over it to block light.I then done a 48hr flush,just ph`d water. then I took the PPM up to 420 as I thought they may now be hungry...... And now it looks like this one is gonna peg it too. Emptied res today and now doing another flush,dont know else to do really??? So if someone could have an educated guess I`d be well happy,Thanks in advance,RM. Appologies for the bad pics.[attachment=o208912]
