Hi, I have a fungal gnat infestation just when i have started the flowering process. "17days" I have found throughout the years that when the Reptile Room gets infested the best way "chemical free" is bringing out the bug zapper & leaving 24/7 for 2 weeks & they are completely erradicated.It actually is a nice sound at night listening to them pop by the hundreds Just wondering, will the black light on the bug zapper throw my flowering process out of whack? This really is the best way of getting rid of these little buggas, i have found, & don't wish to use any chemicals (either natural or poison) if possible. I have been sucking them up with a vacuu…

Has anyone dealt with this before? Thin leaves, crepeish leaves, upturned leaf margins, yellow tips. Virus, Fungas or mould/mildew of the systemic variety is what I am thinking. These plants are jack herer(j) and shiva. Thanks in advance for your help

hey guys, ANYONE EVER USED FLORAMITE BEFORE? i thought i was just getting my problems under control and now i find some black dots on the bottom of my flowering babies...mostly on the upper more resinated/crystaly leaves. Im aware of how much of a problem these guys are and i want to take them out asap. i went out and bought some sm-90 and floramite. if you have experience with either of these i would appreciate some advice on how to correctly use them. my understanding is sm-90 is a anti fungal/mildew that i put in the res and the floramite is a verry powerful spider mite chemical that i need to spray on the leaves. my problem, besides the damn mites. im 5 weeks 3 d…

Was just harvesting my whole one plant for the year and noticed a whole bunch of little black bugs on the stems and getting into the flowers, they aren't scale as they had legs and were moving a round. Anyways is it OK to spay the already harvested branches with neem oil during the drying out phase or am I doomed to be smoking bugs for the rest of the year?

Hi, I'm now in week 6 of flower andbeen having a few problems along the way, but overall things were looking ok. The problems I was having were leaves dying from bottom up, with browning of the leaves usually happening at the tips and sides, but then the whole leaf sort-pof disintegrates. There are now some patches of leaves yellowing etc but on top things looked ok. I've never been able to resolve the problems completely by adjusting the nutrients and ph. A couple of days ago I noticed my plants were giving too much run-off - basically whatever I put in came straight out. I then left them for 2/3 days (fed the bigger one after two days because the coco had dried up), …

The girls are entering their 6th week of flowering and whilst the buds look ok the plants are looking a bit ragged. Last night I thought I saw a tiny web on the very top of the plant. I touched it and there was like a silky strand stuck to my finger tip. There seem to be very tiny brown critters running about on the underside of the fan leaves but not many at this stage. They are on some buds too. I have read plenty on spider mites here and elsewhere on the web. But even with a magnifying glass my eyes are struggling to see the mites. Since this is an emergency I’m trying Yates Natrasoap. (biodegradable and non residual) and no withholding period. They claim it kills sp…
