hey guys,
400 W
12/12
soil
Two plants in flowering for 6 weeks now, both plants started develping these symptoms of discoloration. Tips are affected as well... Texture is fine and no growths are observed, checked for mites and funguses and I didn't find anything..
Thanks in advance!

Pics w/o HPS would allow a much better look...How well did you look at the underside of the leaves? IMHO that looks very much like spider mite damage...could be wrong though are the spots yellowish or orangish?

spider mites. they are tiny, and under the leaves. cut one off, look at it closely under a good white light. you will probably see the bastards storming the courtyard.

fucking borg, assimilating any decent pot plant in their path...

I looked at them again and couldn't find definitive signs of spider mites... pics w/ better lighting : http://imgur.com/a/dzKpZ

REALLY hope it's pH fluctuation and not mites

i don't think it's ph, but i don't see any mites either. however, your pix aren't clear enough for me to see 'in person' (my eyes aren't what they once were).

@RM3 may have some insight

Ok, after seeing the pics...I am almost positive you have a pretty serious thrip infestation...

Look familiar??

i was thinking thrips or aphids, but can't say for certain.

Well the only person who can be certain 100% is the OP. But I am reasonably sure it is thrips. My buddy had them... and let me tell you they suck pretty fucking bad. hard to get control of let alone stop them all together.

Hello guys and thanks for the help..... it's thrips just confirmed it, they're white little flea like bugs, so they're in the early stages, right ?
Anyone recommend a good approach? I've read through GWE and I'm afraid I won't be able to buy the products they recommendin my country

water with neem oil/soap mixture, and layer soil with diatomaceous earth. should fix that right up for you.

I would suggest Azamax...Ebay or Amazon may help you.

not sure if azamax is available globally.
General Hydroponics AzaMax contains 1.2% Azadirachtin
i would think certain countries would prohibit import.

 

[Carlos Caramancha]

thanks for all the help... tomorrow I'm going to a shop nearby, I doubt they'll have Azamax or the other specific brands but they'll prolly have some kind of pest control spray.... wish me luck x_x

neem oil is organic. use to label and cut with dish detergent.

diatomaceous earth is harmless to anything but bugs, available internationally...

good luck!

@$bkbbudz$ @cat of curiosity

have you heard of the brand CannaCure? it's available in my country and the bottle looks the same as Azamax's.
it's a softer approach though... thing is I'm about 3 weeks from harvest, didn't want to apply harsh chemicals if possible

 

[$bkbbudz$]

Tricky...in fact the whole idea of trying to kill and control insects on a plant so close to harvest is kind of tricky. Even pesticides that are safe for flowering plants may leave resins and moisture which could promote mold and mildew so late in flowering. The product you are looking at is a foliar treatment and better used as a preventive measure than a problem solver. However, it appears to be safe for flowering plants. If I were you I would do an all nighter studying on best methods and make a choice based on your findings. Either way you want to act quickly...who wants to smoke dead thrips? Yuck!!!
