Hello, wondering if anyone can identify the problem here. Can you see the white spots on the leaves? That covers most of the plant but doesnt seem to be hurting it too much. I have had whitefly in the past as I grow outdoors, seems only the newer leaves are unaffected. edit: by the way, bottom of leaves look normal as can be? Cheers, 87

Hey guys (and girls), This plant is about 4-5 weeks old, and recently recovered from some overwatering, but it appears to have odd new growth. The leaves are quite thin and the new growth seems to be curling inwards, as well as completely stopping. I've repotted the plant in a new mix of soil + perlite, so hopefully it will get some better drainage. Has anybody experienced something similar to this / has any pointers? Thanks =D (Pictures attatched)

Howdy all just looking for an opinion on this little sucker. as its my first gro.. am a bit unsure what the go with this one is. Dunno if im just being paraniod or have no clue what i'm seeing . Also.. what constitutes "light leak problem" i.e. I may have inadvertently had a splash of light in my room a day or two ago but only lasted half a minute. they're hiding behind plastic..but there is minimal light leakage in the room when lights are on, and external door to room has a 1/4 inch gap under it that I cover with a mat. Are they that sensitive to a minute amount of stress? Sorry to ask the dumb questions.. but some one has to.

Hi all, Im growing Shiva Skunk and am 4 weeks into flower. I'm growing in soil in a grow tent. My problem is that my buds are getting very leafy and are losing trichomes and smell. These are clones taken from first grow. i also had a similar issue in my last grow but not on every plant or on such a lage scale. the leaves on buds are very thin and green. Anyone knows what causes this? Sorry no pics. my camera is busted

Hi all, i've read a few things in the forums, but am new here so any advice would be great. I got given a clone from a hydro set up i've planted it in the ground and its grown pretty well since then. It's now about 3/4ft tall and its just started to develop hairs around the bud sites, but the leaves are slowing turning yellow from the bottom up. I've read that this could be overwatering but my friend thinks a lack of nitrogen. I can take some pictures if they are required. Thanks C.

Hey Guys, Could someone take a look at the pic i've uploaded below. I'm not sure if its normal or not but the lower leaves have started to die (discolour) as my plant grows. This is my first grow and I'm after a more experienced opinion. There's been a hell of a lot of rain here lately so I was thinking maybe its got root rot but I'm just guessing. The strain is white widow. Thanks in advance for the advice.

Hey guys i have my first successful Auto-flower going outside and shes 8 weeks old! The strain is Sweed Seeds Fast Bud suppose to be the fastest growing autoflower from seed to harvest in 8 weeks!! I no that alot of auto flower seeds are very skeptical and seeing that there outdoors they dont quite get the 18/6 that there suppose to get due to other trees blocking the direct sunlight I have been giving her 1/4 nutes from week 3-5 and 1/2 strength from week 5 onwards every week.. Fast bud is suppose to be ready for harvest but is quite obviously not matured yet! i recon by week 12-14 it might be the optimum time for harvest (checking the buds with microscope) C…
