Couchlock you could burn your plants, just over feeding. Open Seaseme is high in nitrogen to supply the plant during stretch so you don't get yellowing on the bottom leaves; Beastie Bloomz is high in phosphate and potash to build buds with no nitrogen.
Look at the leaves, if you see browning on the tips (fertilizer burn) flush with two or three gallons of ph adjusted water and you should be fine. If you're concerned it may be a good idea to flush now before the burn starts to show. You can recover from a burn, it'll just cost you time and a bit of yield and potency.
By "full strength" do you mean 1 tsp of Beastie Blooomz and 1 teaspoon of Open Seaseme? If so then flushing would be a good idea.
