Hi all,
As you can probably see I'm new round here so thanks for reading my first post.
I'm also new to growing and I hope it'll be ok to jump straight in and ask for some advice on what's happening to my three plants. Please see the photos I've posted below of the problem I'm describing.
The plants came to me ten weeks ago as cuttings already rooted by an experienced grower. I'd ask the grower what they thought about this but I don't know them myself, the cuttings having been obtained through a trusted friend of a trusted friend.
I'm not sure what strain the plants are but am waiting to see if we can find out.
The plants were given 18 hours of light for the first 4 weeks, then reduced to 12 and then after another week to 11.
They began to flower about a week after the first light reduction so have now been flowering for about 5 weeks.
We have the plants growing in soil in a spare room measuring 5x4m.
The light is a 600w SHPS and is suspended roughly 18 inches from the tops of the plants.
The soil mix I'll have to find out about to be sure I'm giving the correct information. It came from the commercial plant nursery where my partner works. They grow flowers plants and shrubs from seeds and we used the compost they use to repot young plants . To this we added a quantity of slow release fertiliser from the nursery. Again, I need to check exactly what this contained.
The pots are around 5 litres.
The room temperature is now between 20 and 25 degc. Earlier in the grow it would fall to around 15 c when the light was out during a really cold spell but once the light got going again it would soon be back up in the 20s.
The room is not air cooled.
PH and RH have not been measured.
There are no pests as far as I can see.
I had been watering them more or less every day sharing a litre sized jug between all three, unless they seemed particularly dry. Then I'd give them two litres. Recently my partner decided they were far too dry and gave them a good drenching. She thought I'd been giving them far too little and thought they should be kept moist all the time. I'd been testing the soil by pushing my finger in at the top and it had never felt dry to me. She said she'd put a finger in one of the drain holes in one of the pots and the soil was bone dry. We have kept them very moist ever since then but having read a bit on here I see this is not considered to be the best approach. Indeed I'm wishing I'd looked for some more information before starting my grow. Things might be going rather better now. I'd been led to believe the plants would more or less grow themselves given sufficient water and nutrients.
For fertiliser we used the slow release stuff I mentioned above. We also dissolved some of the same stuff in a gallon of water and fed that to the plants over a two of three day period after about 2 weeks growth under light. I'm wondering if the slow release fertiliser might be the cause of the problem. If we used too much in the soil mix it might not be immediately obvious, until more of the nutrients started to work their way into the plants...?
The problem has been noticeable now for about three weeks and seems to be getting worse. At first I thought it was just leaves dying off because the plant had finished with them so I snipped them off. I got a bit carried away snipping off leaves when the problem continued. I got the idea the plant had finished with its leaves and wanted to concentrate its energy on growing buds so I removed lots of healthy looking leaves too. I know now that was a big mistake but the problem in the photos had started well before I did that so I can't see that as being the cause. The problem is not confined to the tops of the plant but is more noticeable there.
As I say, I wish I'd found this site and the mine of information contained within before I started growing my ladies but what's done is done. I may have made some mistakes but more cuttings can be obtained and hopefully I can learn from this first effort and go on to grow healthier looking plants next time.
I hope I've given enough info on the grow to be of some use in diagnosing what's going on. I'll post up the missing details as soon as possible as well as anything else I might've forgotten just now. I can also post some more photos if needed.
Many thanks for reading, and looking...
