my white rhino plants are starting to turn yellow :thumbdown the damage starts at the top of the plants where the most light is being absorbed which could really hurt my yield if i dont get this problem fixed soon the leaf starts to go a lighter green colour than the lower leaves, then the tips start going yellow, working its way to the stem then the leaf just falls off when touched :thumbdown i have been advised to buy some cannazyme by my mate but i would prefer to get multiple opinions on what the problem could be and how to fix it before i fork out any cash just incase the cannazyme is a waste of time to me... thanks in advance, lets just hope i can save thi…

Hi one and all, have had a recent infestation of scarid fly and am about to spray with pyrethrum as suggested here. The surviving baby is 2 mths old and looks terrible. I remember reading on a thread here that you should put some in with your nutes to attack them from within, but was unable to find any recommendation as to the strength. Can anyone help?

Hi Im a new member here and youll be seeing me mostly in the fungal and ethnobotanical forums however i thought id drop in tao ask what you all think of the use of Trichoderma fungus in mies to control fungal root pathogens For those who dont know Trichoderma is the forest green mould and it lives in woody debris where it breaks down the dead plant matter It is non pathogenic/toxic to plants or humans and few allergic responses have been recorded It is a fungus that gets introduced to soil or growing media to inhibit other fungi Trichoderma exudes potent lytic enzymes as it grows that specifically target the cell membranes of other fungi and so dissolves the compe…

I'm growing in a disused house (with power!!) and a mouse has managed to get into my grow box and has cut down two of my bonzai (M.J.) plants by chewing through the bottom of the stems! If you're growing in a garage, shed or an unused house, get a cat or a snake or you could use poison. But don't use poison if you have pets because if they eat poisoned rodents, they get poisoned too.

:angry: today I discovered heaps of , what looks like tiny , baby flies crawling all over my buds. They dont look like gnats or thrips, just liitle flies. I painfully removed them all & moved the plant & found hundreds of dead ones on the floor . And more flying around the light . They havent been eating away at the plant luckily.but i'm still concerned about the final product , will it be alright ot smoke? I have a crappy little set up for one little plant & I have an organic pellet fertilizer top coating , could they just be flies breeding in the dung on the top? I have moved my plants around a little , from outside to get natural sunlight. any help wou…

Hello stoners. Still trying to sort out this bug prob of me mates. Does anyone have any pics of scarid fly larvae? These little critters seem to have two little snail like eyes/antenae and jump across the surface of the water, and are white in colour. He has placed sticky traps across the top of the medium(clay balls) but has had no adults fly into it yet and has seen no adults buzzing around. Any help would be greatly appreciated before some chemicals are used.

Hey stoners, just been to see me mate as he has had a wierd problem hes never seen before and its got me stumped too. In his res/brain(same) tank he has these little white worm like bugs(very very small) that skim across the surface of the water the same way that mosquito larvae does.I guess the only difference is that these are ON the surface and not below like mozzies. Anybody know?
