just wondering as I've done cuttings a few times now and never had this prob before, my cuts have all rooted, first time i've used peat pellets and the tips on all the leaves are yellow, what do you think it is? nute burn from the nutes in the pellets?
Here is a pic, they have only been given water once but been misted with water while in the prop

Full Version: Yellow Tips On Cuttings?
They'll be fine 
Looks like poor pH control to me, in which case it'll get worse.
Do you correct the pH?

thanks bish.
Never bother with ph, I grow in compost and didn't think ph control was needed ?

Only with loam based composts (like John Innes). These are peat based blocks, peat is loamless so therefore has virtually no buffering potential (same with Bio Bizz).
When you move them on (to a loam based soil) they will be OK, but in those peat based blocks they will get worse without some pH control. Try pH control on one as a test.
ok thanks mate. got a ph kit somewhere, there are ionly two left in the peat now the rest are potted on into John innes #1

Forget about ph when using compost

Why are you advising he use a loam-based compost?
I've always used JI and never had any probs with under/over feeding but the last 2 bags of JI#3 I've found they have gone nitrogen deficient within a week of potting on.
I now use JI#1 for seed and cutting then straight into Humax and I've had no probs this grow and it's much easier to water.
I know that John innes is a loam based compost but not sure what it means, never bothered with ph as i've never had this prob before

Must be a few weak sacks of JI then mate - carry on as normal, & forget about ph
cheers for the quick repsonse mate 
as soon as I posted you were replying
yeah i'll carry on as normal but think i'll stick to the humax as it's cut my watering time in half and the plants seem to like it.
Cheers for the advice i'll forget about the ph, they were only in the jiffys for 7 days and all had rooted, quicker than the last few times when i put them into seed trays with JI seed and cutting.

7 days to root is bang on mate - nice one
