tony2wheelsgood Posted December 7, 2004 Share Posted December 7, 2004 i've had similar symptoms on a plant which i attributed to powdery mildew. there was a very faint white "dust" on the shade leaves which looked like developing crystals (except too early and wrong leaves) and even after treatment the affected leaves went very pale and crisp. the petioles were still damp though when i tried to remove the affected leaves. if nothing else has changed i'd always expect disease. this one sounds like a mould rather than a pest and it it will continue to spread through your stock. i was recommended high ph water but i found it was stripping nutrients from the leaves so i've switched to Leavington Natures Answer bug and fungus killer. It's soap based and having spoken to the boys in the lab at Leavington, i'm convinced that it is safe for us. it's also killing the spider mites that have taken advantage of a sick plant to move in.

Guest nigfis Posted December 7, 2004 Share Posted December 7, 2004 Arnold, Here's another 'just a thought'...... You haven't been getting a little lax at measuring out the Biobizz nutes by any chance? It seems, from my little experience, that the bloom and grow, if over-fed, doesn't produce the classic nute-burn symptoms of yellowing leaf-tips but may well show the kind of symptoms you describe.... Any help? Link to comment Share on other sites More sharing options...
HopefullySoon Posted December 7, 2004 Share Posted December 7, 2004 (edited) Hi Arnie I have exactly the same problem going on with my grow . Its on the GD plants , they are vegg'd up on (weekly Mg+Fe mistings) allmix/grow , and bang on 3 weeks into flower (mg feed at day 10) get the same problem you have . (I did with the last grow as well) The leaves begin to go green - illuminous yellow , with serious reddening of stems . it starts with the lower fan leaves on the plant gradually spreading its way upwards . (only seems to affect fan leaves) new growth is fine . I have tried upping the grow (thinking N def) no good , tried mg thinking it was a hungry plant , no good , tried Fe on the last grow as well no good . Whatever its def in , its got me beat . :headscratch: (followed the ot1 grow shedual to the letter as well ) I'll post some pics up tomorrow when I get in from work .

Arnold Layne Posted December 7, 2004 Author Share Posted December 7, 2004 Tony2wheelsgood (as long as they're on a Fireblade or summat like, Yee - haaaaaaw); No M8, no moulds or anything.

Nigfis - Yup, you may well have it there......., that plus the temp thing I think.

binary Posted December 7, 2004 Share Posted December 7, 2004 (edited) I have exactly the same problem going on with my grow .273519[/snapback] Looks the same as mine too, noticed on mine red stems then the leaves lighten, the veins loose colour before the rest of the leaf turns yellow. With an MG def noticed the veins lost colour later. The leaves begin to go green - illuminous yellow , with serious reddening of stems . it starts with the lower fan leaves on the plant gradually spreading its way upwards . (only seems to affect fan leaves) new growth is fine .I have tried upping the grow (thinking N def) no good , tried mg thinking it was a hungry plant , no good , tried Fe on the last grow as well no good . Whatever its def in , its got me beat . :headscratch: (followed the ot1 grow shedual to the letter as well ) 273519[/snapback] Same here and with no effect, pees me off because I can't understand what's happening. Given up trying to do anything to fix the problem now and hoping the plant survives flowering. Be interesting Arnold if you get to the bottom of the problem, may help us other Biobizz growers, good luck.

Arnold Layne Posted December 7, 2004 Author Share Posted December 7, 2004 Roots - well, as you'd expect from what's on top, that is to say, not quite up to scratch. However, no sign of any health probs - there are roots, white roots, healthy looking but not quite up to the norm. Link to comment Share on other sites More sharing options...
