Would first like to say thanks to everyone who has replied so far and giving me much needed advice.

Yeh the pictures are not the best but hopefully I can get a better camera soon to take more detailed and better pictures so should make everything easier. I read some posts also relating to problems with rockwool but this is my first grow so I will see what results are and if in future I try again I can improve with something more better.

I intended to stick with just PH 5.8 water untill the 5th set of leaves started to show. But like days before that happened the stems went a bit red & looked like an (N) def due to the distilled water I was using.

Compared to mine your beanlings look ok for 7 days.
Cool, ill go read up on your grow log now and hopefully can compare results and earn some tips. I read about the not feed till 5th set of leaves so ill see how it goes.

@ 7 days from seedling I would be adding a dilute rooting hormone like HygroZyme or Voodoo juice just to try and get a good root structure in time for when I'd apply a mild feed. Must have some form of well developed root structure developing before the application of nutes. The roots will then be ready to take up the food right away when feeding commences.

I would continue under 250W but at a distance of 24inches maybe; until i start feeding, then I'd lower the lamp to around 12-18inches.

I would expect to see some reddening on the stems until I start feeding; probably after 10-14 days.

My recent clones were quite red when they arrived. I know that the clone merchant only applies a root hormone to the clones. But after one day of a mild feed at 0.8-1.0EC the reddening has started to go away. (I always look at it as potassium deficiency and potassium silicate is what I use to fix it).
I have some root hormone about so ill try adding some in day or two in dilute form and see how it goes.

As for tip on lights i'm about to move the lights slightly further away and try get a distance of 24 inches are you recommend. I think the slightly yellow leave on one of the seedlings might be due to the lights being too close and rising temperatures now and again. So if i move the lights away it should solve the issue (hopefully)

Thanks for info on the red stems, I wont panic about them just yet then

Good work so far, keep going!!!
Its not sealed currently. I was wondering about it but I guess ill leave it alot right now and think about investing in an air pump/stone etc.


Thanks for everyones tips and advice, I feel slightly more easy about the plants now so ill try to take it easy, relax and let them grow.

I plan on updating this post often thou as want to keep a log of the grow for myself also so next time I know what mistakes I made
