Was gifted with the whole lineup & it's getting to be time to buy . Wow !!!! At 75 on a fixed income aint no way . Pretty much from what I've seen Dynagro Foliage Pro , Jacks 3-1-4 & Maxibloom are possible solutions . Nails down the base . Calmag or calnit with epsom as its Coco . Alternatives to Rhizo ? PK13/14 ? Boost ? Just wanna grow a little medicine & simple is best . What is working or has worked for you ?
Jack's or MegaCrop will be the best bang for your buck. Get away from the bottled stuff, mixing salts isn't too difficult and is way more cost effective.
