Hey guys, I think my girls are about 1 week from harvest (this is my first crop). I have two plants in a run to waste system (their some afghan strain) growing in coco/perlite approx 50/50 Under a 600w HPS They get watered for 4 minutes every 2 hours the light is on Used Canna Vega/Flores A+B through out and PK for a week a few weeks ago I had scarid flies, wouldnt say an infestation just half a dozen or so visible adults at any one time (god knows what was happening under the surface though). I put up with them for a while but then started to notice some yellowing of some of the leaves and thought it might be an inability of my roots to uptake nutes due to them bei…

Hey I've just started my first DWC grow the link is in my signature. I just realised the tips on the first set of leaves are browning and dying! Surely its not time for them to die just yet??? Also the seedling with the protruding root is drooping I think I may have over watered it (Ill have to stop top-feeding this one cos it obviously doesnt need it!) ...Or is it normal for a plant to be a bit droopy while it acclimatises to DWC, this seedling has about 25-30mm of root in the nutrient. However it is only the new set of leaves which are drooping the first set are still horizontal but have a small amount of browning on the tips This one has a small amoun…

Gday all, my plants are about a month old and they were doing fine for awhile until the bottom little sprout leaves began to yellow as did the first set of leaves (you know the ones that are serrated like true leaves but aren't multi-fingered like true leaves), then the tips of the first set of true leaves began to yellow and even brown a little, now all but the newest growth are yellowing at the tips and curling upwards with some of the leaves sporting yellow spots around the middle of the leaf, the main stems of the plants are healthy green but the leaf stems to the affected leaves are a reddish/purple colour. Now I've looked through countless guides and diagnoses tutor…

I have just returned from a few days away and have found my container of recently harvested buds has a thin white downy covering - aka mould The mould is only on the surface and is not originating from the middle of the buds so I am wondering if there is a way of me scraping or washing the mould off? I have baked it in an oven at 150C for 15mins to stop the mould spreading - I read that on the net, dunno if it is going to do that? Has anyone had this experience and if so what did you do? Thanx in advance, Jimbo

So, bringin up a new lot from seed(arent clones so much easier!), they get to about 7days - 2" tall - and seem to fold in the middle and die. Any ideas? When i look at em after the fact its almost like theyve been crushed in that area - which they havent. I tried transplanting a couple and burying them deeper but, after theyve stretched back up again, theyve seemed to do the same thing. I dont think ive over watered or underwatered but wot can it be? Im growing out of seedling trays in a even mix of perlite/vermiculite/coco under a fluro grow light, about 200mm from the light.
