AN works but its definetely not Worth the price.theres a lot of cheaper alternative on the market if you only want something that works. In general , i'd say , more additive the company add to their schedule, more shitty it is. Why would u need 35678 bottle if plant needs 17 elements?
for info,potassium is involved in transpiration and metabolism. in general , plants consume more potassium if the environnement isnt ideal or the light is low.Usually plant that lack of potassium can grow well but the plant is ''weak'' , flexible and fragile.It can affect the taste. most plant can grow well with 1:1 N:K ratio.
theres 3 types of nute; standalone,2-parts and 3 parts. standalone are simple to use and cheaper but they lack of flexibility. 2parts are usually more complete and provide overall the best deal.combine performance and simplicity.3parts provide more flexibility and are used from start to finish.
If you look at the back of bottle you can see what the ingrédients...if theres no info on ingrédients, i suggest to check for another alternate. Avoid product that contain carbonates, it can lead to problem.Carbonates are insoluble and will build up.
If the ammonium content is higher than 20% of the total nitrogen, u may experience some nutes burn and/or calcium deficiency and/or other disorder like ph instability and soft growth. Nitrate are often described as the best nitrogen source for plant production because plants requires less energy to proceed nitrate and promote uptake of P,Ca and K but nitrate only fertlizer are also known to constantly rise ph so low ammonium content is recommanded to balance the alkalinity. I would recommand 10-20% of ammonium.
check how much magnesium it contain.is the source nitrate magnesium or sulfate magnesium? sulfate magnesium is the prefered source because its provide sulfur and more magnesium.If theres no sulfate magnesium in the mix,then theres a great chance you will need sulfate magnesium(aka epsom salt)
In resume, a good fertlizer contain nitrate calcium , phosphate and magnesium sulfate along with micronutrient. nothing else is needed. some company add more potassium than others... That's ok but not needed.
the source of micro is crucial.Edta is know to have bad stability above ph 6.0 and have high affinity for calcium.Theres some study that conclude edta and dtpa increase metal solubility in alkaline ph but reduce uptake of these same metal by plants.Take note that synthetic chelate are not utake by plants. when the metal chelate comes in contact with roots,the chelate release the metal and the chelate go back in solutiion.So theres a risk that edta build-up to a toxic level and edta is well known to be toxic to plants at low concentration.theres a lot of debate and study on synthetic chelate , I invite you to use Google if your looking for more info.
for all these reason i wouldnt recommend edta chelated micronutrient.Iron dtpa is acceptable since its more stable than edta and doesnt share the affinity for calcium but eddha is the prefered source of iron chelate . micronutrient in sulfate form combined with humâtes and organic acids is the way to go IMO.
company who are well known to use edta micro; AN, GH , BOTANICARE, JR PETER.
sorry for my english, i'm too high to correct : (
