So the same plant, a nightingale from mmg seeds, first had one wilting beach, on closer inspection I knowticed a split at the base of the branch, because I did lst ‘d the plant and it wasn’t able to strengthen up enough. I’ve made a paste from simply water and bicarbonate sofa and packet the split and wrapped it in grafting tape. It came good and then went back to dying wwithin a week. Now second branch on opposite side is also wilting. Anyone have any ideas? Chop both branches to stop the spread? I think I should of taken the grafting tape off so t…

So im having a battle with some gnats,im in week 2 of flower, in a 70/30 mix of coco/perlite. i seem to have them under control for now as ive used a scarid fly drench twice now with a 7 day intermission. But my question is will i have to keep applying the drench the whole way through my grow? Or will the two applications have wiped them out completely? Ive not noticed any activity from them for at least 6 days now. This is my first encounter with these little fuckers so any advise would be appreciated!! Posted from the OZ Stoners mobile app

Hi guys, First time grower here. I’ve currently got a bit of a grow journal running. I have a real problem with some of my plants and it only started today or yesterday. I’ve tried researching online what it might be and I just can’t pin point it. I think it may be caterpillars (small ones) but it just looks very very strange! Please, if anyone can shed some light on this and help me eradicate this ASAP I would be very very grateful. It’s happened to two of my plants so far

Growing sativa clones from some bagseed in coco in tents. Noticed one mother slowing down and showing odd 3D leaf curling - lengthways - ie along the central vein, longways - i.e "clawing" and the edges rolling down. Damaged leaves have an odd wet look and a mosaic raised pattern. Lots of damaged new growth as it progressed over a few days. I thought N toxicity so lowered the feed strength then noticed it had hit some seedlings too. Google broad mites cannabis to see photos exactly like what I saw. It looks like multiple nutrient deficiencies all at once and I can now see it starting in some of my other clones. Grabbed a 100X pocket microscope and under the damaged leav…

Got a problem, Buds are forming quite small and dropping off before growing to maturity. The dropped bud looks to be infested with tiny yellow eggs. So far, I'm thinking mites of some description???
