Nutrients will keep your plant healthy, but are not the sole reason for dense nuggets.
Thick dense nuggets are primarily a function of genetics.
By keeping your plant in optimal health will allow the plant to express its genetic potential to the fullest. Part of this formula is GREAT lighting.
You can't just use any old light, feed a plant bulk foods and expect dense nuggets. The plant must have dense nuggets in its DNA.
A 400 Watt HID light for veg and a 600 Watt HID for flowering will certainly give you optimum flowers, however, most LEDs fall far short of their claimed wattage and one rated at 1000 Watts may only be the equivalent of a 150 Watt HID, so you need to check the light you have is really as powerful as advertised, otherwise your plant growth may not be as good as hoped for. The lighting is the biggest factor in producing dense nuggets on plants able to grow dense nuggets. It is then a matter of providing healthy and sustained growth, with favourable temps, pH, air exchange and correct hydration and your plant will grow the flowers it has evolved to grow. There are no magic foods that will change a plant with fluffy buds DNA into one producing solid and dense nuggets you could hammer nails with.
Plant nutrition is relatively simple, but having the right strain with dense nugget DNA and GREAT lighting will give you what you are seeking. Most "Grow" and "Bloom" complete fertilizers have everything required for healthy growth, and then it is up to you and your growing techniques and your set up to then "guide" the plant into growing her best flowers possible.
There are a few extras that may help with plant health and flower production, but a plant can not grow flowers any denser than its genetics have programmed it to do. Things like humic and/or fulvic acids, amino acids, trace element supplements, calcium and magnesium supplements, "P/K" bloom boosters for use during flowering, compost teas, worm "juice", seaweed tonics and myccorrhizae inoculants all help with plant health, but do not cause dense nuggets per se, however they will help the plant to grow her best examples of flowers that she is genetically programmed to do.
Go with well established brands that specialize in cannabis cultivation and all their products will do the job of ensuring great health for your plants - brands like Canna/Bio-Canna, B.A.C., GHE, Hesi, Top Crop, Atami and your own Ionic are all well respected and well proven.
Forget about things like "bud Swell", "Liquid Lead", "P/K 50/30" "Mega Bud" and other dubious products claiming to "turbo charge your buds", these type of products are bordering on steroids with questionable health safety for humans and tend to produce exaggerated buds with little substance and that are also generally inferior to "normally" grown flowers. Like most things in life, there are no free lunches and pumping up flowers with artificial and questionable products which give you "fake" flowers that look like they are wonderful, but then smoke up as D grade muck with shitty highs that give you a headache. Avoid! Avoid! Avoid!
Try and grow your plants with kindness and sympathy and your plants will repay you with kind and delicious flowers. Treat your plant like a machine and she will give you "product" that is for all intents and purposes, cannabis flowers, but bland and without a soul and not something to be proud of.
If you want to WOW your friends, go gently and "tune" into your plants, grow them with love and empathy and everything will be "just right".
Do not get impatient for results, let your plants "do their own thing" they know how to grow, our job as cultivators is to guide the plant to perform to the best of its ability and not to push, push, push. Keep pushing and something will give and the last thing you want is to spend 3-4 months and end up with crap.
Remember too, 18/6 light/dark is optimum for all cannabis, autos or photoperiod plants in veg. This will give you the healthiest and most balanced plants.
Remember three, every healthy green leaf is making energy for your plant to grow. Removing healthy green leaves (defoliation) only results in plants with a reduced capacity to produce energy, causing slower and potentially smaller growth.
Try to only remove yellow leaves, for by the time they are yellow, they have served their purpose.
Remember four - maximum amount of healthy green leaves = maximum energy production = maximum growth and maximum health.
So, good luck and happy growing, love your plants and they will reward you with lovely flowers!
Hope this helps,..........
