Guest mrk Posted February 12, 2011 Share Posted February 12, 2011 (edited) I'm far from being experienced enough to give a definite answer to your problem, however, I had a similar issue when in veg. On your plant some of the leafs look just fine while others appear to be burning at the tips and edges. How far is your lamp from the plant? It could be that your plants are perspiring faster than they would like and the lamp is acting as a magnifying glass therefore burning the leafs. http://www.uk420.com/boards/index.php?showtopic=245051&st=0&p=2558656&fromsearch=1entry2558656 Mrk Edited February 12, 2011 by mrk Link to comment Share on other sites More sharing options...
Justanotherbloke Posted February 12, 2011 Share Posted February 12, 2011 Hiya, I am no expert but have you checked underneath the affected leaves for spider mite? The speckling on the lower leaves in the pic looks very similar to how mites leave them. If you use a jewellers loupe or a magnifying glass or something, you should be able to see any mites or lavae. Hope that helps Bloke Link to comment Share on other sites More sharing options...

Guest Jibbajabba Posted February 12, 2011 Share Posted February 12, 2011 You don't need to ph in soil, im not familiar with the nutes either but for 4 week in veg that ec seems a bit low, but dont quote me on it! Link to comment Share on other sites More sharing options...
sikovdeelas Posted February 12, 2011 Share Posted February 12, 2011 Looks underfed to me, an EC of 1.2 in the 4th week of veg is lower than i usually have it at that stage, try raising your EC to 1.4-1.5 good luck. Link to comment Share on other sites More sharing options...
skunkmc69 Posted February 12, 2011 Author Share Posted February 12, 2011 Benn inspecting the leaves and looks like i might have some sort of bug, but the closest i can find on the site is thrips?? any information would help Link to comment Share on other sites More sharing options...
Justanotherbloke Posted February 12, 2011 Share Posted February 12, 2011 Try sticking "Thrips" into the search bar at the top right hand corned of the page. Thrips leave a silvery trail on the tops of the leaves, can you see this? Hope that helps Bloke Link to comment Share on other sites More sharing options...
skunkmc69 Posted February 12, 2011 Author Share Posted February 12, 2011 (edited) well basically yeah im pretty sure its thrips there are little bugs on the underside of the leafs, kinda orangey in colour and damn small, slight silvery look to the leaves tops whats the best treatment to get rid of em quickly?

madgiz Posted February 12, 2011 Share Posted February 12, 2011 (edited) personally I don't fuck about when it comes to thrips and I hit 'em hard only in the veg stage with two lots of different chemical insecticides..first Scotts bug clear and 3 days later with westlands bug attack.. that'll get the adults,juveniles and recently hatched eggs, it impregnates into the leaf and stem through systemic action to get any stragglers..As long as this is only done in veg that leaves at least 8 weeks for any nasty chemicals to leave the plant.. It is a bit OTT but IME if you don't hit them hard first time then the survivors of the first round of treatment will breed and you inadvertently breed a hardy super thrip that is immune to your treatment.

skunkmc69 Posted February 12, 2011 Author Share Posted February 12, 2011 (edited) Thanks, sounds like a plan, i take it you've done this before and had no bad effects? Ill get on this straight away Edited February 12, 2011 by Owderb Link to comment Share on other sites More sharing options...
madgiz Posted February 12, 2011 Share Posted February 12, 2011 (edited) It's worked for me in the past mate yes.. Edited February 12, 2011 by Owderb Link to comment Share on other sites More sharing options...
erbivore9 Posted February 12, 2011 Share Posted February 12, 2011 Westlands bug attack+ defence really does wipe everything out, not sure whether 8 weeks is quite long enough to get rid of the systemic part though. Link to comment Share on other sites More sharing options...
