very good additive in coco.
dont go to hard on it follow directions actually half directions, bottle directions are on the stronger side for coco users.
but dont go to weak your best of using at half dose in all feeds maby increasing to max rate around mid flower then decreasing by harvest as it will stay in the plant and needs flushing to remove.
will make your plants greener and healthier making them grow faster, branch faster and product thicker stronger branches. i use BUdlink from day 1 at in coco 50% through to when i add PK giving 3 weeks to flush out.
Havnt got to full strenght in recent grows but still seeing the benifit.
directions are different from setup to setup coco needs max 3ml per litre, recycle setup needs more 5ml read instructions well

Mixing always mix budlink first into your water followed by the additive and nute allow 5 mins to mix and go clear before adding next product if done wrong it can make your nute mix milky.
very important never mix directly into res tank say you have a 100lt res mix the 100lts worth of BL into a 10lt bucket of water mix then pour into res..
a very good product and a good brand youve chosen
