Setup...

Room size 3mx3m

lights: 4x 1000w papillon (dimmed to 600w due to heat and weather) might be changing to 6x aircooled lights

Extractor: 900m3/hr air force & 750m3/hr box fan

Intake: 600m3/hr

Nutrients:
Biobizz fish mix
Biobizz grow
Biobizz bloom
Biobizz topmax
Epsom salts

Tempature: day 82f, night 72f, temps got up to 90f with lights on 1000w so turned down to 600w

Vegged for 4 weeks in biobizz soil, first week i used plain water, then 3 weeks 1ml/l fishmix
Flipped on 18th march stopped using fishmix and started using biobizz grow at 1ml/L. Started to add bloom at 2ml/L soon as i seen pistils, then added topmax. 3-4 weeks into flower i was feeding 1ml grow, 4ml bloom, 4ml topmax, added the odd table spoon of epsom salts.

so if they go 8 weeks theyll be down on 18th may? But i think they could go longer not sure, smell is amazing, nice and fruity,

What should i be feeding them now? Should i cut out the grow nutes and carry on adding the bloom/topmax? Lower the dosage of bloom and topmax? Plants have some yellowing but not alot.

When do you recommend harvesting?

Best way to tell is to get an x60 jewelers loupe and check the trichomes. If they are all cloudy and around 25% amber you're good to go.

Always get a jewelers people.

Checking the Trichs works nice. However, you also want to give a few of them a squeeze and make sure they have reached there full density. You should also look for the pistils to almost seem as if they are retracting back into the calyxes.

I would take that from just looks to 9 weeks imo. Hope it works it.

I'd give em a bit of the fish mix, they look hungry for a bit of nitrogen.

I've been using Biobizz nutes recently. I believe they recommend for flower:
2ml Bloom to 1ltr of water (then try moving that up to 3 or even 4ml per ltr). I generally stick to 2ml per Ltr ..maybe 3 at a push.
To this you also add 1ml of BioGrow. Their Rep (a few years ago now) said this was better for flavour in flower then their fishmix ..but a lot of people seem to be using fishmix with great results in flower.
I use BigBud instead of Topmax (or use blackstrap molasses), there seems to be those who think Topmax spoils the flavour (and doesn't do much). I can't state that as 'truth' however.

I'd recommend adding blackstrap molasses to your feeding (look in a health food shop for unsulphured version - it'll be a couple of $ / £). I think it does magical things to the flavour, smell and density of the buds :bigjoint:

When to harvest:
Looking at the buds from here it could be 3+ weeks out :)
As others stated; use a x60 magnifier and go with all/mostly cloudy with 20-40% amber (you'll probably have 5 or less percent clear still, overall). It's a preference thing.
fyi - the more amber, the more couch lock type effects, generally.

The pistils will probably be starting to retract as well (all red with maybe a few white pistils overall). And a little squeeze to check bud density is always good. Or, shaking the branch below the bud to 'feel' the bud weight/density (if you do this through flower you really will 'feel' when the buds become dense).
Though, it all differs strain to strain ..so these are all things to look for generally.

Happy Harvest! bongsmilie

You've easy a week or two more, I use bio bizz, I'd recommend using heaven, forget top max , find a better booster like Big bud etc,if in all mix change to light mix, you have better control over nutes. You don't need to use both fish mix and grow , one will do, feed grow always when you feed( or fish mix) acts as a tonic. Look great well done. As above poster said

Using fishmix in flower leaves a horrible taste, i use fishmix inveg and for the first week or 2 in flower then use biobizz grow, used bioheaven before just seemed very expensive and didnt really gain much from it. Ill give bigbud a try :)

Its near the end of flower, so bit of yellowing is normal?

I could prob ko someone if i thrown one if these nuggets at someomes head theyre solid, ‘tis why i keep thinking to chop, but think they’ve got more growth to go

Iv never used fish mix thanks for that info, teach you a trick with heaven now , only use it once a week, does exactly the same and will save bucks. Holds back deficiencies, probably your fish mix is doing the same job in some way. Big bud is excellent, overdrive probably not so great but I use it anyway as I always have and you get stuck in your ways when everything is good lol

I have not experimented with fish mix, I am waiting on my local supplier to get the whole range in first. They only carry certified stuff, and so far only the 3 base products have been certified.
In medium, I don't increase feeding throughout flowering. I follow the chart until the plant shows burns the first time. At that point, I follow the chart in reverse from the place I'm at. So feeding less and less each week.... Inside the medium, the concentrations are still getting hotter. In hydro you can control the ramp up precisely.
