Red/purple stripes/stems is a direct indication of too low a PH at the rootzone thus locking out Phosphorus.

Raise the PH and the purple stripes will grow out, Pompeygrow has just had the same problem and is on the back end of fixing it now.

Read back a few posts and you'll see.
ph is 6.5-6.7 going in
 
Mind you when I reveged the Psycho I didn't cut the root ball down.

I just let it use all the leftover moisture in the coco and then just give it a trickle of water round the trunk every 2 weeks or so.

what should i up it too or would it be better to test run off
 
Check the PH of the run off, it'll be coming out really low I'll bet.

If you have purple stems and the (soil) PH is 6.5 going in your rootzone and run off could be as low as 4.5 or so.

You need to know the run off PH before you can fix it.
only fed this morning so should i just go give it a couple litres of the same strenth i fed earlier to get run off or diluted mix ?
 
good advice given out there, the terra is buffered the biobizz needs pH ing, theres a sweet spot for pH which allows P uptake and calmag uptake....too low and u get pink lines from P lock out, too high u get calmag def
 
I got a sog with zlh and exo, the lem is more sensitive to pH and likes it a bit more acidic than the exo and considering I bottom feed them its proving to be a challenge to get em both looking right but I top feed the lems with 5.8 and the exo gets 5.9 most of the time...coco obv
 
ok @The Yorkshireman
6.7 going in and 6.5 run off mate was 6.8 earlier goin in when fed but i just recaliberated the penn before checking so not sure if pen was 0.1 off or its just 0.1 lower as was half strength nutes just floors an budxl

All my 4 pheno's of this Pink Lemon are different and it's starting to really grind away at my nerves.

The big purple one seems to be steady away but holds on to Nitrogen longer than the others.

The sherbet lemon one has a fine line between not enough Nitrogen and too much.

The runty one is very sensitive to low PH and doesn't like Nitrogen and claws up very easy.

The kushy one is a Magnesium whore getting worse with slight PH shift.

Well that seems fine, maybe it's just a touch out of the sweet spot.

You got some decent photo's of the stems to show so I can have a look at how bad they are/aren't?
