Hello everyone, this is my second grow. First one was in a make shift single door wardrobe; using a 150w HPS and growing in coco. Got a decent result of just over 4oz.
Slightly improved from my first grow; i am now using a 250w MH bulb, in a dr60 tent and using a single plant DWC bucket.
Here are some picks of previous grow and current.

As you can see my cutting didn't arrive in the best of conditions but it does seem to have picked up some what. The plant seems to have a little shoot coming off from the bottom; shown in the 5th and 67th pictures; don't really know what to do with that. Also there seems to be moss growing on the top of the rock wool; either that or its one very green.
I have been recording my pH, ppm, temp of reservoir and ambient each day. When the solution was recently changed on the 9th the pH was 5.8 and ppm at 520. Now checking it today, the pH had risen to 6.2 and the ppm had also risen to 555. Doesn't this mean the plant is drinking more water than nutrients? Is this because the pH has risen?
I have a small tube heater turned on when the lights go out for the 4 hours. Reservoir is ranging between 17/20C (66F) lights on and dropping sometimes to 15/16C(60). The ambient temperature ranges alot, lights off it has dropped down to 14C (57F) and lights on upto 27C (80F). The plant has been topped a couple of days ago, i do feel it is growing slowly.

Thanks for the read, any help is greatly appreciated. Cheers

Cheers pal, aye was a nice smoke too, very pleased for a first grow. Just cut a circular piece of mylar with a slit in it which has now stopped all light hitting the rockwool.
Any other input would be greatly appreciated.
