Hi guys its my 1st grow so looking for a bit of advice if possible.
Iv got 2 autos in coco, that are in week 6-7 from seed. one was starting to show a little nute burn on leaf tips (so i thought) so i dropped feed a little. But now I'm seeing a couple brown spots on just a couple of leafs. and development seems to have slowed a bit. have been healthy up to now.
From what iv read it looks like Magnesium def? but would like opinions pls.
auto, in coco. 10l pots.
600w hps duel spec. 24/0
Temps - 25-26
R/H 45-55%
Background ec - 0.01
Current feed is: add calmat to get water up to 0.4 - then light dose of canna boost - then add canna A and canna B - final ec is 0.8 ( i was feeding 1.0 but dropped it back a little in last few days.
I water everyday to 20-30% runoff
PH 5.9-6.0
I started 2 seeds a few days apart, same seeds, the other one is looking perfect. they have been fed same feed all along.
Any ideas lads and laddettes?
Cheers
