G'DAY I Got 6 clones (2 Shisks, 2 NLxBB, 2 AK47). All in rockwool about 1-1.5m away from 400w HPS (Can't keep temps high enough under CF's) In plastic cups. Anyway I left a dome on them for first 3 days it is now the 3rd day off. They are all going pale and yellow like they should, but one is about 95% yellow... And im getting a bit worried about her. Should I spray her with some superthrive? No clones have roots coming out of RW yet.... Can't wait to show you all my grow Cheers

G'day all, hope you can help. I have 4 w/widow plants 3 weeks into flowering. The grow room size is 1m x 1m, 400 hps, 2 x 250 fans. 4 x 20" pots all with there own watering rose, and clay beads. Poly in a cirlre with 4 holes ea. When in vegi I was feeding the girls with miracle grow @ 18cf. When I turned them to flower I raised the cf slowly over the first week tot the 24. End of second week I raised the cf to 28. Now the problem. At the end of the second week I noticed some of the fan leaves were tuning yellow from the bottom up. Now these buggers were as big as your hand. Larger in some cases. I thought this was just natural as satavias normally drop the big le…

hi ozstoners, finished a nice gro a while ago of g13 & white rhino. In the crop I have a few immature seeds, nothing major just a few. I don't mind a couple of seeds - even in some of the best Jamaican sensi you come across the occasional seed. I wonder how this happened as I did not find any male heads on any of the plants. Someone advised that I should completely scrub my gro room with bleach to kill any pollen that may be in the room. Bit late for that as I already have another gro on the go & I am not gonna scrub the pots with bleach while the plants are growing obviously. Someone said that I may have got pollen from some mj I was smoking & contaminate…

my 4799 mother has started flowering. bloody bitch she is. I had it on about 20/4. None of the other mums have this problem. Does it have an autoflower tendency or did I stress it into flowering? (mite sprays & forgetting to water sometimes) got it on 24 hour light now, hopefully it'll come good.

My babies have been flowering for a few weeks and have a few weeks to go. Thing i am unsure about is: the very tips of the top buds' hairs have started turning red and looking ready but the rest of the buds 'hairs are still white and the buds are still definately growing. Is there any reason for this? the plants are healthy so there are no problems. This is only my second crop indoors so i am not sure if this is a common thing or not. Any good advice from you good people out there? Could my lights be a little too close to the buds?

A good few days after taking a few clones from my favourite mother, the main stems of all of them turned a purpelish colour. Other than that they are getting new growth, could this be stress? thanks

hey just recently switched to a recirculating setup, supposed to be a bit faster and better yields that pots. well i've had alot of problems since the switch and i'm thinking about canning one of my new setups to go back to pots. one of my systems is an ebb/flow or flood drain table, the other is a three pot top fed type. i'm not having much luck with either as the plants are growing slowly and poorly. i'm going thru nute changes and clean water flushes once per wek. ph is stable now at 6.3-6.6. i'm even using co2 in the flood drain table. there is one exception though, i went and used two varietys for the flood table, afi#1 and g13 and g13xhp. probalbly a bad idea i…

Beating the Summer Heat By Erik Biksa During the heat of the summer many gardeners growing under lights shut down and wait for cooler days. Typically H.I.D (high intensity discharge) lights produce nearly as much heat as they do light, with the exception of some of the newer electronic HID lighting systems. Because they are usually operating in a closed environment, the heat radiated quickly builds up the growing area. If temperatures exceed 85° F in the plant canopy, results are usually diminished. Most grow rooms have an exhaust system to evacuate hot air from the growing environment. The system usually uses a larger CFM fan to pull air out of the growing …

Hi all, I have 3 seedlings under flouro's about 4-6 inches away, They are 16 days old in perlite/vermiculite. They look like they are dying, The leaves are going off colour, They are getting lighter and then heading towards yellow/brown. This is starting from the tips of the leaves heading in, Fast. 2 were transplanted recently and have had their first drink of 1/4 strength nutes, This prob started before the transplant and nutes but the nutes seemed to speed things up. The 2 first round leaves are the healthiest looking, They aint effected. Could this be overwatering, I water from the bottom so the cups sit in a couple mills of water most of the time. Any help or advice …
