Need help ASAP plants yellowing and not sure!

[skunkyuk]

They are 2ft tall.

5 weeks old.

Just been outside 1 week.

Under 52w compact fluros until they went out, now in direct sunlight.

Symtoms happened over 2 days and are getting worse.

Feeding Magi-grow NPK 4:4:4. (thought it would be OK for now)

New developing shoots are normal green colour, its mainly on the old large fan le aves.

Symtoms are on upper and lower leaves but more on the upper ones.


Need help asap i dont think they will last long. If anyone can offer an opinion on this id appreciate it.

PH problems id say, add some garden lime around the base of stem about a good handful.

and water in.

Only thing is aswel, iv got another 3 which are 1ft tall and they look spot on, non of that yellowing at all!?

it'l just be that patch of soil is a bit acidy man. and the plants dont like it.

peace.

Ok fella cheers!

 

[skunkyuk]

Yep you were spot on buddy cheers for that. I wouldnt mind i normally check the ph on every new plot 'duhh'!

WOW, well i went back tonight and to my shock the plant was just about dead. looks really bad. I added lime and water it in last night, after finding the ph to be very acidic, i ch ecked tonight and its ph 6 so pretty good.
Any idea what i can do to help the plants survive? I flushed them last night when i added lime, should i feed them some sort of mild feed?

Thanks for any opinions.http://www.icmag.com/ic/picture.php?albumid=4030&pictureid=58681

too cold at night m8. just make sure you cover them if theres a threat of frost.

and good few handfuls of garden lime too ballense the PH.

the heavy wilting is cold nights water every day and they should pick up.
