Here's a pic of the bigger plant without too much of a problem, sorry about the pic but the lights have just come on. Another unrelated question, do any of you think an ec of 0.5 is too low for this size plant? I seem to remember that I used to run my white rose at around 800ppm at this...

My tap water comes out at over 0.4 ec, so you can see why I can't use it, it's also full of chlorine and some other chlor something hide chemical. Where did you get cal/mag in europe, none of the local grow shops stock it. would love a link I'll buy it tomorrow. I just ordered a batch of...

But the nutrients I use have all that in them I thought?

I have epsom salts do you mean 1 t spoon per dwc bucket (1 bucket is 12 litres of solution), also any ideas on how long before I see an improvement? It's wierd because the biggest plant doesn't seem to be effected that much, although like I say I've just in the last couple of hours noticed very...

Hi, no cal/mag is not available here, I think you can only get it in the US

something I forgot to mention, it started with the smallest plants first, not sure if this is relevant but worth mentioning. I say smallest but they are all around 5-6 inches high and vary from 7 inches round to 12. oh and I'm powering 8 buckets with 2 60l/min air pumps, each bucket has 2 2"...

Hi All, Someone please help me, I've grown in dwc before with no problems albeit many years ago. My current grow is Matanuska tundra, these are about 4 weeks into veg and have started in the last day or so to die off (see pics) I've hunted around the forums to find the problm but am...

Just checked the ppm of the tap water I'm using, ph comes in at 7 to 7.2 and ppm 250 ( a little high ppm but ph neutral).

should mention that the yellowing is most prolific in the grow tips, on the larger older fan leaves it spreads from where the stem attaches and then outward, best view of this is in pic #6 above (the larger leaf toward the bottom of the pic).

ok checked the ph meter, well didn't check it went and got another for comparison, both are reading 5.8ph and both calibrated with ph7 buffer. So hopefully that rules out a ph imbalance. What do you think could this be a sulphur deficiency? Maybe need a bit of epsom salts.....any thoughts people?

At the minute I'm foilar feeding with a half strength solution, bit of a plaster over it but all i can do until i nail the cause down.

I'll try another meter, the one i have is new and calibrated, but ya never know could be faulty. will do it tomorrow and post back then. cheers.

I've checked the roots they are fine, sry should have said been using h2o every couple of days. You think that cold could cause a problem, this strain is from an alaska vallay it rarely gets above 21deg even during the warmest summer. I'd expect it in a sub tropic strain but not this one. I've...

hi all, hope you peeps can help, I know it's a deficiency of some sort, but not sure if iron,mag,calc etc. I'm using ionic bloom fert with ionic boost. room temps are (dark) 16deg (lights on) 21deg humid between 50 and 70. ph at 5.7 ec at 2.0 plants are 2 weeks into flower. using dwc...
