As the stress started short after the synt nutes.. is most likely where you got things started. I would never mix biological feeding with chemical. Is like you let Mana rain from the sky and then suddenly you flood the land with mustard gas. Sure you can let mana rain again but there is nothing left to eat it. You killed your soil micro organisms with that one feeding. You might want to stick to the Mega fertilizer set till the end of the grow, makes most sense as it requires pH to be in the right range, just use Up or Down. Also the silicon.. is a no go, that is most likely chemical.. one drop is one drop to much. If you want to go soil.. follow the right BioBizz table and things should get like you would expect. The main BB product is Bio Heaven... the other products are just build around it. Get a bottle of Kushy Amino Acids and stick to the feeding on the bottle.. is same same like Bio Heaven just 100 times cheaper. To make things easier.. I would just use BB Fish-Mix and BB Bloom, plus add molasses yourself. BB Grow = 75% Fish-Mix + 25% molasses. Using Grow is a start but not enough to get the BRIX number over 12%.. so you have to add molasses anyhow.. hence skip Grow and just add more Molasses.. stuff is cheap too ^^
If you use Freedom Farm Premium Classic (green bag), BioBizz Fish-Mix, Bloom, TopMax (or similar Humic and Fulvic acids), BB Bio Heaven or Kushy Amino Acids, Kushy or Freedom Farm Kelp Extract and de-sulphurated molasses with rain water. You have all to run a grow till the end, nothing else needed. And just stick to the BioBizz grow table.. they work, I ran over 1000 plants with it.
