First grow, any advice?

So after a number of years toying with the idea, lurking around on multiple forums and nearly getting on it twice I've finally started my first grow! I decided to grow in coco basically because I knew i wanted to go with more of a hydro set up than soil and I read that coco was more forgiving towards the plants than clay pebbles and stuff, also the thought of growing my buds in some kinda coconut stuff just sounded like it was a pretty cool idea to me man so when I found out my local hydro store had canna coco and all that jazz and seeing so many people recommend it I thought that was the best way to go. So basically as far as nutrients go all I have at the moment is canna coco a+b and rhizotonic. In the lighting department I decided to go with a 250W CFL up until flower (currently on an 18/6 light schedule) and then when I get to that point I was going to switch to a 200W HPS cos i read that they were better for flowering. Probably will also start adding some pk13/14 around then but thats not for another while so I'm not really going to worry about it now. I'm growing acapulco gold as per recommendation from a good mate of mine who knows his fair share about bud.

Since I'm growing for me and my roommate and we manage to smoke a fair amount I was thinking about going for a ScrOG as well to just increase the yield a little, I don't know if that'll work so well with the acapulco gold but eh it's my first try and I'm not exactly expecting perfect results here I'm just trying to learn for the future really. Plus I'm going to be on holiday for a while about a week or two after I'm expecting to harvest so ill only really get a taste of the harvest this time round so if the yield is a little low I won't really mind to be honest I'll just be happy if I manage to keep them all alive and get them to flower in the end.

At the beginning when I first germd the seeds (14 days ago) it was kinda a spontaneous thing and it basically sent me and my roommate all over the place gathering equipment so that when they popped we would be ready (for any other noobs out there I warn you it was a bad plan lets just say mistakes were made) We basically ended up with a little closet about 80x50cm so I guess about a foot and a half by two feet? covered in mylar on the inside with a small fan hanging on one end of it, managed to also get a drip feeding system set up fairly easily. Anyway once we got it all set up and everything I got a little excited and just put the seedlings which had by then sprouted straight into larger pots with a 70/30 mix of coco and perlite, totally forgetting everything I had read telling my otherwise but eh you guys know how it is sometimes. As I said mistakes were made.

So far I've been watering them a tiny bit every day with water and 1/4strength nutes (a+b and rhizontonic) and kept the temperature at around 80F while the lights are on and 65F when they're off with the humidity around 40-50% for most of the time. They're kinda doing ok at the moment but some of them are showing a bit of yellowing but like not on the tips at all really just like the base of the leaves towards the stem. I don't really know what to do with them because I feel like i might just be worrying too much but I mean this is new to me so it could be anything or nothing at all as far as I know (although id lean towards a magnesium deficiency if I had to guess). the pics here are from this morning, couldn't get a good shot of all of them cos my camera is kinda bulky and i didn't want to move the light so it is what it is. I'll be posting updates here though every couple of days probably (unless nothing happens) just so any other noobs out there who are growing their own can do a lil comparison, although i get super busy sometimes with my work and so i might blank out for a while every now and then. But yeah please post any advice or whatever you want really I'm just excited to get started learning how to grow for myself and if anyone else wants to post their set ups or plants go right ahead I'd love to learn about any methods/techniques you guys have to offer! Oh and if you saw my other post on the new members forum I know I'm repeating myself a bit here but I mean I know I talk/type a lot (I mean jesus christ look how big that^ turned out to be) so I figured best keep it out of everyone else's way rather than clogging up other forums with my lengthy noob antics haha

Good for you to start your grow man, your plants look just fine. Best advice I could give at this stage in growth is to make sure you are giving them a good correct nutrient solution. I would advise to measure your ppm (about 300 - 400ppm for seedlings) so you know how much nutes they are getting, and def ph your water to 5.8 for a coco grow (imo). Proper ph and ppm's are very important. When you get the right mixture, you don't need to water every day. Give them a decent ammt of water then give them a couple days till the pots lighten up a bit, just don't let them droop. Other than that, remember you are only going to get so many grams per watt of lighting, so I would get a 600w hps with a dimable ballast which usually have 3 or more adjustments so you can run at lower wattages if you really want.

Ya, i wouldnt constantly water either. Nice little set up though ;) id water like a cup to a cup and a half around the plant once every couple days. You probably know from your reading that over watering is the most common mistake for new growers, but on the otherhand you did add a ton of pearlite in there too didnt ya? Soo you may be watering more frequently. Either way, constant drip isnt the best way to water a plant. A good drink and then wait until its dry or the container is light in your hand again.

One piece of advice, don't write a wall of text as an opening post to a thread, you end up with no replies.
yeah I realise man I was just a lil stoned and it kinda just went on... i'll try to keep it short in future

thanks man and yeah my ppm was at about 382 yesterday and the pH was around 5.8 as well but do you really think i need a 600W light? I thought if I tried anything that big in my little closet it'd fry the plants

600 way too big for that space. 200 is fine, you might even have heat issues so you might want to try and make a diy cool tube.

yeah they are fem seeds luckily and i was thinking i might have a heat issue thanks for confirming it and the cool tube suggestion, ill try to stick one together and let you know how it goes

Ok so I woke up and came down this morning to find that some of the leaves are curling up, I think its heat stress (temps got up to about ~85F) but I'm not really sure how to deal with it, I have a fan in the closet but its just for air movement, my extractor fan is on the way and should be here in a couple days. Anyone got any ideas on how to keep the temperatures down between now and then?

Stop worrying so much man lol. If I've learned anything from my first grow - which is still flowering - these plants are insanely resilient - some strains anyway, I only have experience with this one- Check my posts, you can see that I've had my difficulties but they all went away as soon as I stopped with the "first child syndrome". I only water when they're dry - if I think it's time I'll wait one more day to make sure - be careful with the nutes but as far as PH goes - my experience so far is it's a waste of time to worry about it. I had way more issues when I was trying to adjust the levels. I haven't PH'd anything since one month before flowering - Yes I know some other strains are harder to grow but I would imagine that at some point all strains are going to act in the same manner.

freeze 1 gallon milk jug/icecream containers full of water. leave or hang them in cabinet. be prepared for condensation to drip everywhere. temperatures will drop. replace as needed

PS: ignore ^nazis. do worry about your pH in coco. Its more or less important in different growing media. its important in coco

yeah you may well have a point haha and luckily for me the pH hasn't really been a problem its kinda stayed around 5.8-6.2, ill check out your grow though man

I'm growing in a soilless medium very similar to coco, so no you are wrong and it is not that important. Again for cream of the crop, top notch lab produced shit then ya worry about every little detail. If you're just a pot head you wants some organic home grown good bud then stop doctoring everything. It's not that complicated. Do you think outdoor soil is PH'd to the perfect number??? Just check to make sure it's not acidic and that's all.

They look a little warm and I'm guessing the rh is pretty low too. You can spray them with water, it helps when they are young.

I've actually been doing that and keeping the rh between about 30-50%, This is what the looked like this morning when I came down, one of them has these yellow spots on the leaves, I saw them yesterday but they were tiny so I wasn't worried but now they've gotten a bit worse, any idea what it is? i was spraying water on them to keep the rh up so i thought it might have been that the water just magnified the light and burnt it but i duno it looks odd so I thought I'd ask
