no yellow!!
no, my plant all look good apart from the blackish dots, which seems to be spreading and killing leaves -but no yellow) ive grown this strain in same setup before so i think i got nute /ph/ temps correct...
just thinking its botrytis, damn if was nutes etc could fix that easier than stripping of affected leaves. its not bugs,, i had spidermite in the past =( so know what to look for in that respect. any other ideas ?? help appreciated dude!! |

the info that you left out (about no clorisis or def.) makes it a different isssue entirely
Phosphorus (P) deficiency during vegatative growth. Many people mistaken this for a fungus, and leaves the color dull greyish to a black, with a very brittle texture later on. Get us a pic somehow, we have some good diagnositions here, most issues get resolved Last edited by Ganja Guerrilla; 11-03-2006 at 06:52 PM. |

poor pics but....
![]() ![]() the first was maybe the worst of em.. took it of yesterday before neeming the second is the worst of what was there just now (poor quality pics, sorry) and was just a tip, so cut off. i have smaller dots more like the original thread starters pics, maybe a bit less of them but on a fair few leaves on 4-5 plants. additional info: 7 x 8-9 inch tall young plants 2-3 weeks old, 1 week in nft. only 4 or 5 plants have some dots others none! notice just now when took pic that the as the black spots grow they are becoming more discoloured red/brown. Also remembered that 1-2 days into nft i made a balls-up with res solution, noticed ph was a bit high 6.1 so went to bring down to 5.5 - 5.7 and... oops shit too much 4.5 4.2 going down shit, quickly pulled feed from tray... took another 10 - 20 mins til i was flushing thru at 5.7 was only brief but for 10-20 sec was pumping in v low ph!!! Another factor. though dots were present before this... hmm really am hoping it is that ph prob and that as they continue in the correct ph they will recover, ah and the more affected plants are nearer the feed intake...... though its been 2-3 days since the ph accident (stonehead clumsy me) they still worsened despite being at 5.7 since. could be explained perhaps by the rockwool cubes absorbing some of that super low ph, i didnt remove cubes for a thorough ph adjusted soak. but im gonna =) maybe as i go through all this im figuring it out!!! But i DID have these spots before, and they were not subjected to such ph or nute extremes!!! dunno, what ya think ganga? sorry for long post and poor pic quality (new camera should arrive next week) any other second opinions?? all help appreciated. toke on....

I still think thats PH and nute lockout are in play here. that first pic looks similar to phosphours def. in the vegatative state. PH swings will lockout phosphours and sounds like you had some problems
Im not versed enough in hydro, I think chimera grows hyro, if you dont get second opinions from some hydro gurus today start a new post so its seen tomorrow |
