thanks allot mate, I have been thinking, trying, thinking, trying, you get the hang of it, for a few weeks now, hopefully it now gets sorted.
Only other question though aqua if you can be bothered,
My last reservoir change my water climbed and stopped at 7.6, after four or so days it was 7.9, EC started at 1.3 and lowered with the ph rise (a good thing right?) at 1.1EC I topped up the res with some nutrients which lowered the ph to 7.6 and raised the EC to 1.3. the next day I raised EC to 1.4, day after 1.5. Plants have responded well to increased nutrients, growth and colour, I am a bit behind the feeding schedule as I was afraid of overdoing it with nutrients initially, as I am getting a little bit of confidence and getting used to NFT I decided to higher it closer to where they should be.
why? why am I having plants with no curled leaves, no yellowing tips, poor colouring, no growth? how can I have a ph of up to 8.0 and have flat happy leaves, growth, green, no leaf discolouration?
maybe this is an easy answer, but its got me stuffed!
