Cannabis Troubleshooting

hello again, i've got this plant growing outdoors, a few weeks into heading and it is developing rusty little spots on the fan and bigger leaves. it seems to spread over the leaf until it turns brown and drops off. it doesn't effect the new growth, and doesn't seem to have stunted.(still growing well) all the other plants are doing well. only this one seems to be affected. it is not deficient in any major or secondary nutes. ph is also fine. any ideas?

Please help This plant is in a flood and drain system using rockwool and usein one 1000 watt hps to grow under. I only vegged them for a short time so i could tell which ones were female an then regenrate after they have had matured and then use the regenrated plant as mother plants to take clones from. I only have to plants goin this one a bubble gum straine and white rhino that looks fine commpared to this one. They both get the same nuits. I have been usein a few diffrent nuits to try to help them but not really sure what they really need. What is the problem?

heh stoners, ... So there are pretty distinct symptoms that will tell you that you have over-fertilised your plants, the fan leaves will tell you soon enough. But i was thinking more on the side of leaf diagnosis and watering/ moisture levels, ie from looking at the fan leaves on a plant that is relatively healthy, correct PH, healthy root structure, showing no signs of being over-fertilised, can you establish whether you are under or overwatering or whether you have too much light/heat or a combination of all these factors. So like without moisture meters, picking up pots, temp. guage... whatever, no tools, can you diagnose from looking at the leaves only... if …

I posted on here with my problem a couple of weeks ago and you guys seemed to solve that one, so here's another one for you. All the leaf tips on one of my plants are turning brown and dying. Any suggestions ?

I woke up to find a 2 week old seedling had been munched on during the night and being so small had collapsed under the weight of whatever munched on it I couldn't find any grubs or other insects on the plants and couldn't work out what it was. Last night I went out to check the plants after dark and found a fat arsed earwig heading towards another plant. I read in a book that these bastards eat holes in the leaves at night and Pyrethrum is the recommended solution but the plants had already been sprayed with pyrethrum so that doesn't work. Does anyone know any other ways (preferably chemical free) to stop my plants becoming an allnight diner for earwigs? Thank…

There are no bugs on the plant, just in the medium...and they dont fly around.... Cheers for da help....

Hi, I am a relatively new grower, grown once before but this my first time with hydroponics. I have 5, 10 cm plants, in grodan 3 inch blocks. The plants look healthy but have a very slight white discolouration on some the leaves. More disturbingly there is a white mould growing on the top of the grow block. There are no roots showing through the block so I cannot see any roots at the moment. Has anybody seen this before or any advice would be very much appreciated.

Hi ya growers. Every time i grow i am either not noticing or too stoned to notice about fan leaves: Once you turn to 12/12 should you start losing fan leaves near the bottom and around the middle of the plant? By losing i mean going yellow and dying off- not too many but enough to get paraniod about. Anybody who takes notice of these things may be able to help. thanks
