Indoor 2nd Grow. First wasn't so great.

Hi all. So I made it to the end of my first grow with a critical auto. Had a power cut at one stage for a day but made it to the end with a pretty small yield.

Nutrition:
Sensi grow and sensi bloom part a and b. I used the recommended dosage per litre on the bottle and watered every second day or so.

Medium:
Soil with John innes and mixed with about 30% perlite.

Led:
Generic small light, this is probably a big factor. Also my humidifier shorted the light out at 70% at one point causing a power cut. Going to upgrade this soon to a spider 300w with Samsung diodes that's hopefully a bit more waterproof.

Grow tent:
2.5 X 2.5ft

My next grow is likely to be Jack herer. Possibly going for 3 to 4 of them.

Should I change to a different growing medium? What other nute consideration should I be thinking about here? Just trying to see where I mainly went wrong. Also to note. The early stages of the plant looked very healthy but late veg and flowering I think could have gone better.

Hi bro and nice to meet you anyhow as you said your light is a massive part of it also regarding media you could stick with soil or if you fancied a try with coco but with that you need to feed with food every watering you could maybe try megacrop as loads of folks on here use it so you could get tons of help

Hi Tom nice to meet you too. I was considering the Coco medium. Could I use drip auto irrigation on that or do you need it to have a dry period between watering?

I heard I should not have been using nutes every time I watered with autos. Would this be a factor maybe?

with coco you don't want your pot to dry out and yes even autoflowers with coco need nutes every watering never just water

Top watering coco with automatic irrigation works really well. In my opinion, better than automatic sub-irrigation. If you have not already done it, study the information on Cocoforcannabis.com, the peeps that publish the site know what they are doing. Other than adjusting to lower nute levels for automatics rather than photos, you can just set a grow up exactly as they describe.

As to the number of plants in your 2.5x2.5, you do not want 3 or 4 plants in there, especially not in coco. Unless the strain(s) are well known to be compact, you should assume about 4 sq. ft. per plant. You could get away with two small strains in there, but you would fill the tent with one large auto.

Good luck with it.

Hello and welcome - If you are using Coco as the others have said you will need to water regularly, I run Wilma drip system with four pots in coco and hydroton mix and that is pretty much all I have ever used as a medium - the nutes in my opinion are much of a muchness. As St. Tom says though - the light is paramount to getting bigger and better results.

Good luck

I'm guessing if you watered/fed every other day, than your girls may have been over-watered. They need to lose at least 50% of pot weight before watering. Humidly & air flow, (especially humidity), can lessing/extend watering periods and you shouldn't feed every watering with soil. Depending on the soil, there's at least a 2 week period where your girls don't need any nutes at all, (a seed has enough stored energy to last at least 10 days or so). Until you get the feel for it, weigh your pots when wet & you can easily weigh again after to know when to water/feed again. Of course as the plant gets bigger you should re-weigh when wet, as the plant will add weight as it grows!
