Hi ! This is my first indoor grow and I have some problems with my plant which I don't really know how to rectify.
Would appreciate any help given.
Before I start, I would like to state that I have read through the sticky threads on this section regarding plant diagnosis and treatment. But with a lack of experience I am unable to accurately pinpoint a solution. At the moment it looks like gnat flies / N deficiency. But any ideas will be appreciated.
Some basic information :
1. Indoor grow under 4 23W CFL (two 6500k and two 2700k) plus 2 LED lights at 12W and 13W (both 3000k).
2. Growing medium is organic soil (some decent loose soil I found locally to ensure roots can grow easily).
3. Plant is 16 days old as of today. Transplanted once a week ago from a 3 inch pot to a 7 inch pot.
4. I have only watered it 3 times since germination. 1st time at 2 days old, 2nd time after another 7 days and the 3rd time after another 6 days (yesterday). Each time I water I ensured that it is bone dry (soil has started "cracking" at side plus finger test).
For the 1st and 2nd watering I measured the pH at about 7 and added a little organic liquid seaweed kelp. Then the tips started becoming brown which I thought was nute burn and only watered with distilled water at around 6.5 pH the 3rd time.
5. Room temperature is usually 27-29 degrees in the day (82 F) and 24-26 degrees at night (77 F).
3 fans (1 intake, 1 inside blowing around and 1 exhaust) so there is ample wind movement).
6. This is Nirvana's blue mystic autoflower feminized.
Now to the questions :
1. It is growing very slow, and I suspect it may be stunted. I checked online and saw pictures and most plants were much larger at 16 days old. Can someone confirm this or is it still rooting ?
2. The yellowing started from the tips of the oldest true leaves, and the new leaves were a healthy green. But lately this yellowing is spreading and even the younger leaves are beginning to turn yellow. There are also some brown spot/lines on the oldest true leaves (see picture). What deficiency is this ? There are so many possibilities I cannot even say with confidence anymore. Any experienced advance will be appreciated.
The local gardening shop is just 10 minutes drive away. I can quickly go get whatever is needed. But I would really like to know what to add first before I rush and add something I would later regret.
Thanks in advance
