To Control N

     Hi Folks, thanks for dropping in, please do leave comments, whatever?

So, The situation with growth is way grand for circumstances, The "mainlined" and topped plants were a slow start but now have thrived after 9 weeks to become tall and bushy.

Planted in Biobizz all-mix in 7 Gal fabric pots, plants get watered every 24-36hrs constantly, sometimes sit in 2 inches of runoff overnight, mostly well soaked for the next day ahead.

 Temps have been very high and pots cool to 22-24C at night but rise to 32C in the shade of noon despite covering pots with netting and reflective sheets to keep sunlight off most of the floor area.

Have been adding minimal G & B nutes (by BAC) all along due to understanding all-mix is full-on which seems a good idea, tried and tested formula, but, I have now become aware that I am a bit clueless in regard to it's (all-mix) true intended properties and may need to be very careful with what is added to the feeds, so far the level of G & B feed combined has been at a fluctuating level of between .15 up to .35 of EC (not much?) with .15 of Cal Mag and Silica added, all combined to measure an approximate EC of between .28 and.50, my water is currently filtered to an EC of .02 (yes it's that low with rinsed and new filter)... So...

So far no problem, the buds are starting to show their hairs for the last 5 days an all seems good... except, I am concerned about the future feeding, in particular to deliver the correct doses of Nitrogen!!:ermm:

I felt it's good to build up an outdoor plant that gets thrashed by cyclonic winds and needs to endure harsh Spanish sun, grow them well nourished and green, I thought no deficiency should exist, no struggle for the plant when trying to build up at night? (my fancy thinking again:innocent:)

Damn, must run upstairs and erect the darkening covers to block the street light reflections....it's all go:sweaty:

Here, a few quick photos, wondering about nodes space and stretching??

your just getting into flower, and they look pretty heavy on the sativa front I'd budget at least another third on the vertical height.

careful throttling back too far this early in flower. You will taste it either way. organic or synthetic the key is threading the needle of N uptake of whatever variety we are growing in late flower. the best way I can explain this is by asking you if you had to slaughter a cow to get a steak, and you wanted a good one. Would you kill the cow that was starved or the fat one?

 

 keep the feed stable, focused, and on schedule.

 

Over come the vertical issues with pinching, tying, and bending , I say go full on bdsm  with her if she'll take it, but don't top her now. if you cut anything take it off the bottom third you will be happier and better served on your result. 

 

e2a: correct a typo and say she looks healthy too

Thanks for your input @ygdop Yes there seems to be a surprise sativa element coming out of two plants and the concern was that N could be surging from 'Hot' compost which is watered 'everyday' liberating more nutes by giving double the normal daily waterings? Mind you the other plants are holding down better.

 So... Do some "full-on tying down"?? indeed it will turn the whole roof into a giant scrog:thumsup: Thanks for mention because there probably needs to be some pruning management. I'll get some better photos tomorrow and a bunch of bamboo and let's see what can be done.

Cheers.

don't really know what the growing situation is over there but if you could do some light dep's and pull some tarps at 11.5 hours of daylight, then go back out at bedtime and pull the tarps back, that would get her to tighten up a bit.

This is all wrong. 

Follow a wet dry cycle. Watering every day and letting them sit in it is a recipe for root rot. 

Try raising you pots off the floor so no heat can be transferred. Pop them on some wood or something that's a poor conductor of heat. 

 

 

I dont really get the issue here. There is no nitrogen  excess here. Just watch how much you give for the rest of the grow and you will be fine.

Thanks for dropping in @blackpoolbouncer yes you have generalised quite accurately,

There is wrong going on, It's like growing on a baking sheet however the tubs are batoned off the floor surface.

 Also am discovering that 7Gal is not sufficient in this environment to comfortably bed in for a proper wet/dry cycle, things go from the tub weight feeling heavy to light weight within a hot afternoon.

 Now for the Bloom feed spec. it's BAC organic bloom it's NPK is  6.2%-5.0%-6.2%  The N value seems quite high for Blooming?

May as well mention that the 'Organic PK Booster' specs are  4.2%-1.8%-7.8% :mellow: The N value seems quite high for the product.

 Of course I shall use the local recommendations here for Nutes on the next grow or should using another product with lesser N values be considered now?

 Certainly have stopped using a drop of 'Grow' bottle since yesterday.

 Cheers and Good day to you too.

In fact... comparing the Bloom bottle specs. to the Booster bottle specs. seems to add a touch of (further) uncertainty, referring the 'P' values in both?

 Not much Boost in the "Booster"?

Yes, times like this it would be better to use what everybody else uses and understands how to tweak.
