Thanks WH:jointsmile:

I reckon I will need to add more light but will wait untill I get an idea of how many confirmed females there is.

Do you know what could be causing the yellowing of the leaf tips as it seems to also be happening to the main plants on a couple of fan leaves, there is also a redish purple vaining thas appearing on some of the branches & main stems. There was a PH fluctuation the other day. The nutes PPM dropped quite rapidly from the 679 & is now between 200 -300. If its a deficiency what additives would you recommend.

Since putting them on 12/12 they have been racing each other to the light generally I adjust the chains to a 4" distance during the day & by the next morning the middle plant has grown till the leaves just touch the bulb. This has resulted in some burning on the leaves closest. The tallest plants are 20 " now thats a growth of 8 inches since wednesday.
JackHerer Reviewed by JackHerer on . First time grow KC Brains Skunk #1 & White KC Hi All This is my first grow seems to be going alright. I did also have some NL during germination & propogation but they all failled to make it to seedlings. WIll have to do a dedicated NL grow with the rest of my seeds as I reckon I know where I made mistakes. These seedlings are about two weeks old and as I say it seems to be going ok but a couple have started to droop a bit since being put in the larger rockwool cubes & te NFT tank. They are under a 250W MH bulb by Solarburst Rating: 5
