bigfatbuds Posted November 16, 2006 Share Posted November 16, 2006 (edited) Hi folks, This is my first post on uk420 so first off would like to say hi to everyone. I have read a lot of posts over the last two weeks which has really helped me with my first grow. I am growing 2 femaleseeds grapefruits which have been under 24hr blue enviro for the last week. The first 2 jaggy leaves that have formed are turning a very light green/yellow colour and the secondary leaves which are very small at the moment are also very light and have a brown tip. Also the growth rate has really slowed over the past few days. I was wondering if anyone knows the cause of this and what I can do to fix it. forgive the picture, the macro on my camera is a bit shit.

adddw Posted November 16, 2006 Share Posted November 16, 2006 repot em upto bottom node and use some perlite this time Link to comment Share on other sites More sharing options...
steevo Posted November 16, 2006 Share Posted November 16, 2006 Don't go into Allmix either! it's already stressed enough without risking nute burn from too 'hot' a mix. Link to comment Share on other sites More sharing options...

Owderb Posted November 16, 2006 Share Posted November 16, 2006 (edited) looks like nitrogen deficiency to me. no sign nute burn or leaf curl. And what can cause any lock out.........Too much nutes thats what A seedling has enough stored nutes to keep itself going for the first 10-14 days Owd Edited November 16, 2006 by Owderb Link to comment Share on other sites More sharing options...
steevo Posted November 16, 2006 Share Posted November 16, 2006 I'm guessing cotyleydons compostverte but that's not such a good idea at that stage of it's life imo. Link to comment Share on other sites More sharing options...
compostverte Posted November 16, 2006 Share Posted November 16, 2006 (edited) not such a good idea at that stage of it's life imo. I agree. And it's actually amazingly short anyway. A bit too much to hope it would have enough strength to make new roots. Edited November 16, 2006 by compostverte Link to comment Share on other sites More sharing options...
Arnold Layne Posted November 16, 2006 Share Posted November 16, 2006 Pot them up???? They're already in too big a pot IMHO. And, I suspect, in a compost not well suited to Cannabis growing by virtue of being either too rich or having a Ph outside of the range required.. More info is required, as Owderb has said, before anyone can venture a half-useful diagnosis. Link to comment Share on other sites More sharing options...
adddw Posted November 16, 2006 Share Posted November 16, 2006 sorri I did mean the cotyleydons but this was general advice for when he did pot up not like immediately...the plant will feed off the cotyleydons too at the beginning so no nutes needed and with good compost you need no nutes till flower imo Link to comment Share on other sites More sharing options...
Arnold Layne Posted November 16, 2006 Share Posted November 16, 2006 whats daft about that? i often start seedlings in 3 gallon or 5 gallon pots. No transplant stress then, duh! It is generally accepted as bad practice to start seeds in bigger pots. They will not form a decent and dense rootball, but rather a thin maze of lazy roots. It is far better to start them off in very small pots, and wait till the rootball is fully formed before potting them up in gentle (small) stages until they finally enter the size of pot required for flowering. Since rootball health and vigour is vital to yield and potential-realisation, this is an important part of growing and needs to be understood. This I have learned by experience and by listening to more seasoned growers. There is clearly a problem with the compost being used in this pot, and until we know what compost is being used all and any diagnoses can only be guesswork.

compostverte Posted November 16, 2006 Share Posted November 16, 2006 whats daft about that? Sorry if I jumped on you - it just seemed a bit of an odd suggestion to come from an experienced grower. Link to comment Share on other sites More sharing options...
