organics- fertilization

have 4 three week old white widow plants,2 weeks 24hr/ 1 week 18-6. they seem to b doing brilliant.i am using dr hornbys iguana juice-for veg growth.have only used it once so far and was wondering how often i should use it.its not exactly full of info on the side of the container any book ive read says to follow the instructions on the fertilizer.
also is there meant to be bigish sized lumps in it.i know it contains fish emulshion but the pipette i got wit it from your man in the shop, keeps getting blocked when measuring.not really a problem cos i can just use a spoon but i was concerned it might be gone off or something

 

Here's a link you may want to peruse:
http://www.advancednutrients.com/organic_nutrients.html
There's not much dosing info there either though.

In talking with a friend of mine who's the most knowledgable grower I know (and who owns a grow shop), he told me that Iguana Juice is THE BEST organic nutrient available.

 

sound.unfortunately dats more or less the same as whats on the side of the bottle.even more unfortunately it seems that theyre all fúckin males.cúnt.
thanks anyway
