I am so grateful for my SEA-90! I have been using it as a foliar spray and adding it as you suggested to my main nutrients. 2 of 4 of my late teen mother plants that I raised from cuttings we’re getting yellow leaves and looking rather sad. Amazingly a high percentage of the yellowing leaves are turning green again. I used 1 teaspoon magnesium/ Epsom salts plus a half teaspoon of the SEA-90 per 1 gallon of RO water. I believe the SEA-90 is the secret ingredient! This morning I decided to be bold and used a full teaspoon of see 90 for one gallon of RO water plus the one teaspoon of magnesium. Approximately one hour later I could see a noticeable increase of branch/ leaf Vibrance.
It’s so impressive how potent it is. I mixed a 30 gallon batch in my NFT reservoir with Emerald Harvest nutrients as directed yielding a PPM Of 770. Then I added approximately half the recommended amount of see 90 and my PPM shot up to approximately 1500! And the transplants are thriving beautifully.
Anyhow, I just wanted to thank you once again 4 your kind responses and to give you my good news. I am a customer for life.
