yo, your lady looks beautiful! +rep. you have a classic case of nitrogen deficiency. just give it a little more N than usual and she should green right up! the buds are small because i believe your light is not used efficienctly. your plant is very tall and you should have thinned out the bottom before flowering. 250W doesnt have enough par to penetrate that deep into your canopy

oh thanks for the super quick reply urgod, im a little calm now... though the issues are much bigger...
so this is classic case of N def ?
i have all BioBizz line, Algamic has some N in it but i think very little, should i boost with Algamic next watering ?

agree about light, i definitely will upgrade to 600 next growth.

yeah i am 99% positive its nitrogen deficiency. uhh idk whats in the biobizz line, but you should just multiply all your NPK ratio out. for example i use 8ml of 5-0-1 and 16ml of 0-5-4 per gallon... so my NPK is 40-80-72... try to keep it as close to 1-2-2 npk ratio as possible during flowering.

ok!
looks like BioGrow has the most N in it (8.0%) .... but also many other stuff NH4, NO3, P205 etc ...
Bloom has 2.0%, Algamic 0.1%, Heaven 0.91%

should i boost Grow on next fedding.. (in week 5 flower) ????

Are you following a chart that suggests cutting out N?

i'd just use a tiny bit of biogrow just to green up the leaves. you can also foilar spray the leaves as well, just nothing too concentrated. you dont want the plant focusing its energy back on growing leaves hahaha :P if ur in week 5, you should boost bloom. hit it with a high PK ratio

Or a nice balance of NPK to keep her looking healthy. I never foliar spray my plants when they have flowers, just not a good idea IMO.

Just pulled the chart are you doing all mix or light mix? I like the light mix at week 5. I'd like to know what ppm it puts you at though.

i know Biobizz are aimed to their soil but i dont use em.
im having someone who makes my soil mix.. which is actualy similar to their All-Mix, then im adding perlite. i dont have ppm meter so i cant answer that question, my water here are known to very very good in general...

this is the chart im using, have a look, Soil on top, coco below http://media.shopy.co.il/shops/795/24977.jpg

i was told to always spray during flwering until the last few weeks when the bud starts to proper close up. i reckon spraying also gives crystalier buds dont u think ?

no. do NOT spray during flower process, it can cause mold and damage the flower, its also not recommended to have high humidity during flower process from the same reasons.

basically now on u should be feeding in every watering , keep using all the line and just add 1ml per litre of water of the biogrow bottle , its an overall deficiency of npk if it had no p deficiency it wouldnt go crispy yeloow/orange/brown
