Hey,
First time grower here.
Plant:
Automatic Super Skunk from White Label Seedbank.
Setup:
Setup is indoor. 400w HPS with a Sunmaster Dual Spectrum Grow+ bulb.
Tent is 1.2m*1.2m*2m with desk fan for air circulation.
Temp is on average 27-29 degrees Celsius.
Humidity averages around 45% - 55%.
Light cycle is 24hrs.
Medium:
Growing in Canna Terra soil.
Pot size is 15L, 30cm tall.
Watering:
I've been watering whenever pots feel light and topsoil is crusty.
This was initially every 5 days but is now down to every 3.
Every 2nd feed has been a flush of pure water.
Nutrients:
I have been using Platinum nutrients (French).
These are a Grow, a Bloom, and an Enzyme booster (this was only given once ~1 week before flowering).
Very light doses have been given but 2 weeks ago i increased the dose slightly.
Doses are still half the manufacturers recommended amount.
Stage:
Plant is 36 days old (as of 1/9/13). It began flowering on day 29.
Its 53cm tall and roughly 60cm wide.
Problem:
Initial problems began on day 8 after sprouting. Leaves looked patchy with bright patches on very dark leaves. Tips began to curl up without drying out.
2 of the early fan leaves completely closed. Sorry but i have no pics from this stage.
Over the next 2 weeks new growth continued to improve although still with some level of discoloration and slight curling.
This was during a heatwave the likes of which we don't usually get here so the temp in the tent was always 30 degrees Celsius minimum. Peaks hit ~34.
Once the weather got cooler thing started looking up although 3 days ago i noticed some fresh problems.
There are now brown spots appearing on nearly 1/3 of the leaves. This is occurring all over the plant but mainly in the middle section.
Some leaves (~5 of them) have started yellowing and withering. These leaves have the worst necrosis.
Also stems up near the top are turning red on their topside.
Research has told me that this is more than likely a Mg or Ca problem. I just don't know if its a deficiency or pH lockout.
I have an analog pH testing device (that i do not trust). This is currently reading slightly above seven although its accuracy seems to be mainly on the acidic side so whether its 7.1 or 7.5 i do not know.
I have 2 auto amnesia haze (1 flowering, the other vegging) that are both growing perfectly fine in this environment and with same nutrients, watering etc.
Sorry for poor quality pics.
Any help at all will be greatly appreciated.
I'm going to hit the local grow shop tomorrow for advice and maybe pick up some cal-mag solution and possibly pH down.
Cheers,
Dave.
