hi guys..I have 4 green crack going..3 in promix,1 in miracle grow..all vegged for about 60 days and started bloom feed when flipped..temps around 60-65,rh is around 50-60,ph is normally between 6.3 and 6.8.
Using 2 300w leds calibrated mostly in the red spectrum at about 24 inches height and also threw in a few small led bulbs at 2700k when flipped.
I had some watering and N issues but they were fixed.
After 2 1/2 weeks with no signs of flowering I decided to put them in 48 hours darkness.
Today I turned the lights back on and are still absolutely no signs whatsoever ,vertical growth has pretty much come to a halt. Today marks the end of week 3.
Am I supposed to be seeing pre-flowers after this dark period or do I have to continue to wait.
It's really starting to piss me off bc this is supposed to be an 8-9 week strain but it looks to be taking a hell of alot longer than that and I can honestly see myself firing these fkn things out the door and growing some autos.
2 1/2 months wasted on these gd things..not to mention the electricity costs.
If there is a problem with the other 3, wouldn't the 1 in miracle grow soil still flower within the normal time frame bc it doesn't need to be fed?
I'm getting tired of putting all this work into something that is not giving back.
Please help!..im at my wits end.
Which Promix formula are you using?
I have not used promix but it looks like they have some with food already in the mix and some other mixes that are inert.
Already addressed by Thundercat, your temps are kind of low.
But there are some other factors here like Vapor Pressure Deficit, which is a compound measurement (temp/rh matrix) of your plant's atmosphere. Plants outside of their VPD comfort zone won't thrive and this will stunt/slow their growth. Stick your head in a tent with the proper VPD and its a wonderland that you'll never want to leave, I wish I could live in that kind of atmosphere.
According to the temps/rh you provided, your vpd is on the low side which can cause slower and even deformed growth. Depending on the surface temperature of the leaf (do you have one of those laser temp guns?) your VPD may be even farther from ideal. Your humidity and temps should try to stay relative to each other within certain bounds. Not taking other factors into account like leaf surface temperature, you should be at least 70f for 60%rh but ideally you'd want 77f - 81f. There are lots of VPD charts out there and some calculators if you want to fine tune it.
Also, be careful going too far into flower with rh that high and temps that low, those are good bud rot conditions and you don't want to lose all that hard work. If you can get your rh down in flower, like 40% you'll start to draw out that frosting.
Most importantly be patient, they will take the time they need and there isn't much you can do to rush things.
Everything else looks pretty good. Keep us posted!
to be sure that everything is ok about this..maybe when i am not home the electricity drops down for 15 mins.<--- I WILL GET DESTROYED, maybe the plants dont, but i will definitely get..i will buy a digital timer with batteries and the problem will be solved once forever.
..lol..just trying to get through this grow successfully..1 was leaf burned bc the small led bulbs dropped but i didnt notice until i checked on them the next day
