Bubbler Ph Doing My Head In..Pls. Help

hi all,
hope someone can help me before i evict these ladies lol. this isnt my first grow but is my virgin scrog and have run into some baaadass ph issues. i have a 40ltr bubbler running at ec-1.8 (just upped nutes from 1.6 to try and sort problem) 2weeks into flower.
the problem is the ph will drop from 5.8 right down to 4.5 some days. i correct with tap water but still falls rapidly. @tap ph-7.3, ec 0.4 .....canna aqua, riznotonic, canazym and nothing else. mix up all nutes and additives first then ph down.
they dont look unhealthy...far from it roots fluffy n white and no nasty smells from res but i know this problem will kill em if not sorted i am lovin the simplicity of the bubbler but am losing patience with the ph issue. will post pics once i know how to lol.....any advice would be gr8.....thanx guys

ahhaaa pics may help ,,,,ph still droppin ...ho hum

hey man, are you dechlorinating your tap water? tap water has added chemicals including chlorine that can hurt your plants. also could be water temps that keep fucking with the ph

tap water sat for 24 hrs bubbling before use but changed to ferro regional nutes and all ph probs gone and ma girls are lookin like las vegas show girls and are the best yet......temp in res is constant 21 and room temp is 24 droppin to 18/19 when lights off. hope all stays as it is ...thanx for input.

Hey JTO, glad to hear your PH prob is finally worked out.
I notice a few ppl having probs with Canna products in DWC.

not had these probs before so was a bit suprised when swapping nutes sorted it as i hadnt had a prob with canna until i started the bubblers, im amazed at the feedback my girls are givin me regards their new menu.....cant seem to upload pics any more right now but will do as soon as i figure it out, thanx

ha ha damn picture demon couldnt defeat meeeeeee ha ha.

Hell yeah man. nice dark healthy green all over.
Gonna have bud sites all over that mamajama!!

not bad for nearly 4 weeks me thinks

8 weeks exactly....could go another week dont u think???

yeah definitely looks like it can handle more time. The pistils still look white all over.
Lookin real good!

I like that cola..thats a nice cola lulz Looks prettyful! REP to you sir Happy growing and I'm def. wantin to hear some smoke reports after

yep thanx for feedback, decided to give them another week just to make sure lol. cant wait to take em for a spin. will post reports on smoke as im using new nutes as well so want to know the taste hasnt been affected too much. at last its all coming together, thanx

One thing I learned is that the breeders never give you the right flowering time they probably lessen it by 10 days or so to make it more appealing to the grower, also you never know how they grew their plants was it hydro, dirt, soiless ??? who knows. Best way is to do it yourself with a 100x's microscope from Radio Shack ( 15 bucks ) and check the trichomes your self.

got my boys national geographic microscope....was good enough to see most of the trichs were still clear but shouldnt be long now. lol

hi all.....had one ready before the others so she fell on my scissors....kindly enough my wife offered to hold her for me while i took her portrait ...was pleased on both counts...
