IMO u need hormones or some wieght additive like silica.....
OR shit you can get from hydro shop.....
Cell dividers
Some additves help the plants grow quicker by making their cells divide quicker.
Organic additives such as monsta bud, psychobud and megabud cause plants to grow faster in this way
Monstabud and Psychobud are the same except Psychobud is more concentrated.
Both are available in an additive to nutrient in separate formulas for grow, flower and harvest/final stages.
Megabud is used only in the fist and third week of flowering and is very high performance.
Bio Earth Sea Acids are a unique product that can be used alongside the other products for very fast plant metabolism, meaning faster growth and flowering
Weight Adders
Silica...is always my first !
Potassium is stored in the flower/fruit during the flowering process.
To add weight, products like weight plus use potassium to add weight
Weight plus 1ltr is $20 and is added at 1ml per liter
Other potassium products are Potash plus and Canna PK1314 but are not as pH stable as weight plus which is fully balanced and should not affect your pH
& PGR`s
ROCK JUICE -
CHLORMEQUAT CHLORIDE
Acetyl Thiozolidine 4 Carboxylic Acid
Amino Acids – Protein Hyderolysate
ETC ETC ETC
Also what are you feeding (sry if missed that) at what PPM, any additives other than reg nutes ?? Whats your range on ph... Jack likes 5.5-5.6
Looks to me as if there is alot of nitrogen (steam is long skinny or inter-node length)
and NOT ENOUGH phos and pottasium ...not saying deficency but plants require alot to fill out and reach max yield... During flower MJ`s: Nitrogen and phosphorus uptake increase up to 250%, and potassium requirements increase 400%.
The uptake of calcium and magnesium increases 150%.
It will only show deficency as you go below min requirment to live (not grow)
AND IT COULD JUST GENE`S....... LOL & more light the better.....but you got her that far and big (though stretched) so I dont see why you dont have bigger buds ? except the above !
hope that helped!?
