As advised by others in another thread, i have decided to start my own thread in an attemp to try to fix my problem. **Posts taken from my other posts** It's been a week since i transplanted to larger pots and my problem still exists If someone could take a look at the pics, that would be very much appreciated. Is it magnesium or manganese? Or neither? And... This one was potted using a $12 bag of "re-potting" soil and from my previous experience with cheap(read bunnings special) mixes, this one does not appear to have a lot of bark. Not sure of the brand of potting mix but it did mention have 3 months worth of food in it. This plant is actually 12 weeks old now …

Im using a recirc. Ive been flushing the rootmass during the night cycle so as to use all the light cycle for growing. Is this enough, or should a flush include some time under the lights? And if so how long. H&G only reccomend 3 days at the end of a grow; ive been more inclined to stop nutes at week 7.0 (depending on maturinty) then flush for another week. OR is it better to grow for the entire 8 weeks and add a week of flushing?

Hi all, Just started to feed my plants. Not too sure how much to feed them. i put .5ml of a and .5ml of b gold dutchmaster in 250ml of water, and that was evenlu spreed between 7 plants, with 40ml of water each too. plants are about 4weeks from piping out soil. The slightly bigger ones were showing signs of yellowing so that's why i fed them last night. Any pointers would be appreciated. 600w mh, Good ventilation, 12-1 system, potting mix soil.

I have a Ph tester for my aquarium but i don't trust its accuracy. I'm new to hydroponics and needing to buy some tools of the trade if you could buy anything what would you suggest ? I was looking on ebay and i noticed this Ph Tester but i'm not sure if the applications right ? I'm thinking of setting up a bottle co2 injection system later on which this looks like it might integrate in nicely, but besides ph is there anything else i should be testing for and keeping my eye on ? Cheers !

Hi guys, im Van. Used to be a member but havent been on for ages and forgot my p/word so had to come back as a newby. Got a problem with a few of my girls - leaf necrosis that started out as a suttle discolouration and has become bad necrosis. Neglected my ph in the way that I would bring it down to 5.7 one night and then not attend to it the next night and then the night after that it would hover around 6.7. Am on top of it now but symptoms seem to be worse. Thought it was a Calcium deficiency because of its original look and my high ph but since have added Calcium and monitored ph closely and has gotten worse. Im stumped. I run Coco and perlite - mostly coco, run to…
