Hello everyone, great to arrive at this forum, cheers to all fellow growers.
First of all many thanks to GWE team for running this site, and to the supporting community.
I have been reading articles here for some time now, and decided to give it a shot and grow one.
I figured for my first time I would go with an autoflowering feminised white widow (I think it's from Hemp Brothers), to see whats what,
I have the following setup:
3'x3' grow tent
400W HID lamp in an enclosed aircooled reflector
Ventilation has max capability of around 250 CFM now, but used to be quite inefficient before.
I have been following a strategy of my own, which perhaps has proven bad.
I am not chasing maximum yelds or crazy efficiency, maybe someday I will, but now it's a single plant kinda laid back fun.
I am not saying I was aiming for organic grow, but wanted to grow in soil and avoid boosters and ferlitizers, so I use kind of regular soil that matched the pH range, mixed up with perlite, some coconut and a tad of dolomite, a mix I have often stumbled upon on several growing sites and forums.
I germinated in a peat cube (something like jiffy) and as soon as the seed has risen and opened the cotyledons I planted the cube in the soil, put it under 24/0 while keeping my light source somewhat higher than recommended because back then I was having temperature issues, and still the temp would be around 29-30 degrees most of the time
Temperatures now range from 22 to 26 sometimes 28 C RH@35-45%, and as a leftover of attempted temperature rescue the plant is now (still) on a 5/1 cycle, I thought I would also try watering or spraying the leaves only during dark.
First thing that I find a little strange about my grow is stretching. There is very very little stretch on my plant. I am currently in the middle of week 3 and new grow nodes keep popping up, and leaves are quite crowded. I am doing some lousy LST on it...
Finally, the issue I am having, for most time I thought it was related to my watering schedule which I have been testing different kinds of and still don't know...
When I go by the rule of checking the top inch or two of the soil, and watering whenever it gets dry, I end up watering at least once a day, I think my soil has proper drainage, each watering I use sprayer directly on the soil until runoff appears.
First one or two leaves, altho otherwise healthy appearance, started very gently curling side edges up, now about 1/1,5 weeks later those couple leaves have started yellowing on the edges with slight curling up, while a couple other leaves seem to have darker tips curling down (see photos), as in nitrogen toxicity, which I never assumed would be the case, since I am not using any nutrients and the soil is pretty ordinary with no gizmos pre-mixed. I tried adjusting the light because I thought perhaps was overfeeding with lumens, however doubtful because lamp was around 10" at lowest, now it is ~20" away.
The leaves feel a little stiff and harsh to the touch.
It's not the best photo, but it's all I have atm.
So am I overwatering, underwatering or what is going on I don't really know
Any comments or suggestions about that issue, as well as any other tips would be much appreciated.

apart from nitrogen (which is absent in mineral water), so it's the only potential deficiency I could think of, but I guess gardening soil should provide enough, not sure how much can watering flush out of the soil... also the symptoms don't exactly seem like it. The claw thing kinda comes and goes, so I guess I am going to ignore it for now and assume nitrogen levels are not an issue.
