Hi Stinky,

Ok, here's the story.

The plants are being fed the range of bio bizz products - bio grow, bio bloom & top max. Soil is bio bizz all mix. I can't remember what the NPK is on the front of the bottles, grow and bloom do say, top max has nothing but I do not have them to hand at present.

PH of the the tap water is 6.8-6.9, ran 600ml through the plant last night and it came out at 6.5, acceptable levels.

Have been adding the following amounts of nutes per litre of water:

bio grow - 2.5ml
bio bloom - 3.5ml
top max - 1ml

Been feeding them all with about 500ml each. The bottles say on them to add this with every watering, so I have.

Have also been following the bio bizz feeding schedule (attached below) a bit, but obviously not to the letter, on when to start it with nutes etc.

This particular plant is one from an earlier question which I believe had nute burn (yellow tips on fan leaves) and yourself confirmed. Fed it only plain water for two feeds after that (500ml each time) and then started it back on the nutes (as per feeding above)

Being a newbie to this, I haven't transplanted them once. I now realise that transplanting as they grow up is better for them, so leason learned. I grew the seeds in peat pellets, then when the roots were showing through the bottom, put them straight in to the pots they are in now (10L - 2.2 gallon). Been in these pots for probably just over 2 month now - 4 weeks veg, coming to end of week 5 flower this Friday

The other two plants seem to be getting on alright, bit of yellowing but nothing as serious as this one.

Any more info you need to help with diagnosis, let me know.

Cheers.
