Hi all Im less than 2 weeks away from harvest and my plants have just started showing signs of spidermite. I’d like to spray them now if possible before they reach plague proportions but I’m worried about the chemical showing up in the taste of the buds. So far I have been recommended the two sprays in the pictures, but does anybody have any firsthand experience using these? Or a product I could use to flush the chemicals from the plant afterwards?

HELP! Whats wrong with my Plant? Hey, fellow growers! I need your help! I'm having some issues with fertilizers while cultivating this incredible strain, and I have no clue what to do! I've been using Advanced Nutrients fertilizers as recommended, but something's not right. My plants are showing some strange symptoms, and I can't tell if it's nutrient overload or deficiency. I'm a bit lost here! Here are some problems I've noticed:The leaves are turning yellow or brown. Some leaves are curling or wilting. Flower development seems stunted or abnormal. Flower production is low, and the buds aren't forming properly. I…

For some reason my timer didn’t flick my lights on today, and I didn’t spot it until 8hrs after she was due to wake up. She’s on 18/6 now, and I’m nowhere near ready to flip her (she’s just gone thru her first manifold, so there’s barely anything to her). I got her light back on as soon I noticed it; I guess what I want to know is do I switch her back off at her regular time? I don’t mind pushing her lighting schedule back a bit if that’ll help… Or do I have to switch her to 12/12 now? It’s my first grow, and I’m worried I screwed it Posted from the OZ Stoners mobile app

Hi everyone, My plant is showing these signs, what could it be? Im upto week 5, been feeding my girls half strength pH perfect Advanced Nutrients since week 3 (2 feeds worth so far), and just gave them cal-mag half strength too. I water every 3 days. Im using Canna Terra mixed 50/50 with Coco coir. My plants were almost touching my lights too so I just adjusted up them up higher Thanks for any help Sent from my CPH1831 using Tapatalk

Hi. First time post. Presuming the worst but hoping all is not lost. Harvesting and noticing browning areas on the bases of what I’m assuming are the glumes perhaps? It doesn’t appear to be very infested yet to the naked eyes, but I’m assuming it’s only a matter of time. Can any one tell me if this is botrytis, and that in this early stage is it still salvageable? Thanks. Posted from the OZ Stoners mobile app

Hi All, First timer in outdoor pot with unknown strain . Just noticed every leaf top has these tiny white spits. Guessing spider mites or mildew.Sprayed with eco oil today. Also notice that every leaf tip is brown ( tiny bit only) and slightly curled up. Hope the wizards can advise. Cheers Posted from the OZ Stoners mobile app

Hi All, they list multiple different bugs for spider mites: lacewings, tiny mite feeding ladybirds (Stethorus spp.), predatory gall-midges (Feltiella spp.) and a variety of predatory mites (including Phytoseiulus persimilis and Neoseiulus californicus) Anyone had any luck with bugs in hydro and killed the spider mites? What bug/s did you use?

Hi every, I'm new to the forums and I'm also a first time grower, my plants have been doing rather well so far, but I have come across a few (issues?) With the plant as it has started to flower, some of the leaves on 1 of the 2 plants has what looks like very minor tip burn, and both plants have very bright almost fluro green/yellowish new growth, and also some purple stems. Both plants are auto gsc, I was hoping I could get some opinions, thanks in advance.

I over fed my plants and burned, that was just the beginning of many problems... I tried to save it by defoliating ALL the burnt leaves (which was 99% of them), then I re-vedged it. When the plant got re-vedged the leaves were shiny and round... I didn't like them so I devoliated, all of the round leaves... Currently the plant has been under 13 off 11 on cycle for about two weeks. Bud production has not slowed down, thank God.... but the very small leaves that I have started to turn grayish purple on the tips, not sure if that is a bad or a good thing at the moment... to be honest I am not sure what to do... Should I cut it and start over? I have a Blue Dream and Mac1 tha…
