B-52 in the first week

B-52 is spose to help with nutrient absorption... So if your using it on its own- what exactly is it going to help the plant uptake? if its in soil then no, just water for now is fine or a very very weak Veg nute. Like 1/8 strength and then only once and go back to water for the next time, then the 1/8th strength mix then water again. That should get you to week 2.5-3 and then you go to 1/4 or 1/2 strength nutes. You can add a few drops up to a ML per liter of that 1/8th strength nute solution to use on the seedlings and that will be fine but on its own it wont really do much...it wont hurt in weak doses but too strong anything at this stage will hurt it more than it helps. Personally id wait 3 or 4 more days THEN use that 1/8th nute solution with a few drops of the B-52 and then water then the Nutes then water ect. Look at it like this- if you dont feed her the worst case is she grows a bit slower for a few days- no big deal right? But if you feed her now the worst thing that can happen is she dies. Hope that helps my friend.
