I have posted this in the organic it as well, but as am somewhere inbetween thought i would post it up here as well.
If anyone has any experiance of using bio nova nutes it would be great to share experiences. Unfortuntly not many people seem to use them and the company doesnt give much info on feeding shedules. dont want to go wrong!!
using bio nova BN SOIL supermix mineral organic fertiliser 3.5ml/litre + bio nova BN PK 13+14 complex mineral fertiliser at 0.8ml/litre.
The supermix is ratio npk 5-2-4
the pk is 0-13-14
Generaly water on one day (ph'd to about 6.2) and nutes on the second again ph 6.2
I am growing Jack flash (vegged for over 2month) and nebula (vegged for about 5weeks). grown in allmix. jack flash in approx 20liter pots and most nebulas in approx 10litre pots but some in 20 litre. 6 x 600 sodium aircooled reflectors fan in and fan out which take air from the room and runs through the reflectors venting into chimnley spelling???.
Just going into 5th week flower. They are looking bushy and the buds are forming nicely but they are much more pale than I would expect. Dont think it's a N deficiency as with bio nova you continue using the same grow nutrient all the way through with just the addition of pk in the flower. if fact i wonder if this gives them too much N. ratio 5-2-4 and i am giving the 3.5/ litre with addition of pk. was wondering if it could be a magnesium deficiency as we have hard water (ph above 7.5) and i have herd the calcium can lock magnesium out. The supermix does contain magnesium, however i dont know if it is enough 0.9%Mg. They have all had at least one feed of epson salts at 1tsp/7litres.
Lower down there is some yellow leaves and some leaves that are yellow but still with green veins. However I would kind of expect this. I am more worried about the general overall pale colour.
I flushed all the plants last week with 3 x the volume of the pots with water that i ph'd with phos acid to about 6.2 as the run of was suggesting the ph in the soil was somewhere towards 7. however i dont think it really brought the ph of the soil down as the runoff was not that different than before i flushed.
Since i have flushed there is also some browning around the edges of the leaves at the top of the colas.The effected leaves have curled upwards. It has only happened to the nebulas. jack flash uneffected. Happened to approx half of the nebulas. lower leaves unaffected.
thought there was a possibility it was heat burn so have moved lights futher away. now approx 2ft away and also are air coolled reflectors. the overall heat in the room is a bit high (approx 29-30 deg c) however it hasn't really ever seemed like much of a problem so far.
the curling and brown looked a bit like nute burn but seeing as hey have been flushed and i have not raised the feed levels i don't think it is.
hmm tra la la mystery!!
yeah really would appreciate any comments I am hoping to get enough smoke off them to last me a good while and make the electricity bill worthwhile! anything help to make sure ti goes okay is much appreciated.
loving growing them anyway. beautiful plant I garden a lot but this is now my favorite plant to grow. wish i could do it outdoors naturally though.
cheers
