label problems

hi folk's been lurkin for a few months, great site, lotsa help, i'm on my first grow and got a couple of questions, i just put my plants onto 1/2 strength feed (canna aqua), when i added the feed the ph dropped from 6 to 3.4, the label says the ph should not need adjusting after the feed has been added but i thought i would have to keep adjusting my ph :wtf:, also i have just moved my rockwool blocks into 11 ltr pots with clay pellets and i cant seem too get the watering times right could someone mabye give me a general starting point i can adjust from im just going to start using 15 mins every 4 hours thanks in advance for any help:thumbsup:

What hydro setup are you running?


Drip? Bucket? NFT?

sry about the delay got internet probs got the prob sorted with the watering thanks changed to a home made drip system and have a good recovery with all, still a little confused with the labeling though but i am adjusting my ph anyway and that seems to be working ok

i use nft tanks i run my pumps 15 min on 15 min off for the 12 hours the lights are on then 1 15 min feed when lights are off.:thumbsup::thumbsup::thumbsup:
