Pepe Ramon Posted March 13, 2010 Share Posted March 13, 2010 Have you checked for spider mite underneath the leaves with white spots on? Link to comment Share on other sites More sharing options...
T187 Posted March 13, 2010 Share Posted March 13, 2010 looks like a they been fed slightly to much??? might be wrong wait for a few more responses , they leafs dont look that bad in the picture ive seen far worse on mine i dont tend to worry to much as leafs tend to change colour anyway due to the nutes and the PK levels can also change them yellow to purple colour which i got at moment on my afghan kush anyway good luck hope some1 gives u answers u need T187!!!

Scouser Posted March 13, 2010 Share Posted March 13, 2010 Isn't an EC of 1-3 a bit vague? i.e, shouldn't you be aiming for like 1.6 1.8 2.0, depending on the strain of course? Link to comment Share on other sites More sharing options...

Scouser Posted March 13, 2010 Share Posted March 13, 2010 If the bluelab pen uses the decimal scale, a safe final EC level would be around 1.4 - 1.6, using the CF scale (just the EC * 10) that's 14 to 16. Do you have a filter or something on your water pipes somewhere? Link to comment Share on other sites More sharing options...

naahsty Posted March 13, 2010 Share Posted March 13, 2010 (edited) If I had plants 5 weeks into veg I would be feeding them an EC between 1.4 to 1.6 and PH 5.8. I reckon yours may need some food. edited - spelling Edited March 13, 2010 by naahsty Link to comment Share on other sites More sharing options...
Peppi Posted March 13, 2010 Author Share Posted March 13, 2010 (edited) cheers bud i will up the ec to 1-4 next feed ph of 6 and do a flea bomb just in case there are mites on them cant see any but my eyesight isnt great tbh see what happens then peppi Edited March 13, 2010 by Peppi Link to comment Share on other sites More sharing options...
T1 Posted March 13, 2010 Share Posted March 13, 2010 I cant help with your problem peppi but watch out for those flea bombs, they always say move any plants, fish tanks and animals from the room they are to be set off in, so i dont think its safe to do that in your grow room.

Guest Tutu Posted March 13, 2010 Share Posted March 13, 2010 got the flea bomb info from here bud !!!http://www.uk420.com/boards/index.php?auto...showarticle=493 ill take the plants out while i do this of course ,but then if there are mites on the plants they will be untouched ,so ill still need to do something else to rid the plants of them any suggestions ??????? peppi Spray the plants with alcohol, toxic to spidermites (In fact all life) and evaporates to nothing leaving little or no residue. I'd use iso as it's cheaper and available in 99.9% also any spare can always be used for oil. Link to comment Share on other sites More sharing options...

I've no experience of how flammable that stuff is/isn't. Link to comment Share on other sites More sharing options...
