Too much or not enough

Hi all, been growing this white rhino in a 2l bottle, just a little experiment i thought id try 12/12 from seed.

Iv never really understood how much nutes to give on a 12/12 grow like this.
I started off with just water for the first couple of weeks then started with 1ml bloom per litre, and last feed was 2ml bloom p/l {plant magic}. Medium is bio bizz all mix. Watering every couple of days, but i realy think i have to increase the waterings, a few times the soils been bone dry. Just had a few other growroom problems lately and this plants been at the bottom of my list on jobs to do unfortunately/

So is this too much nutes, or not enough ? Yellowing has been starting at the tips and moving inward. What does this suggest ? Nitrogen ?
Could heat do this much damage, been wrestling with temps for a bit too, been hitting 85f under a 250w hps.

Thanks for looking.
 
85 is no problems for MJ plants, I wouldnt say it got heat stress unless it was hitting 95ish +. Looks like it wants more nutrients to me. This looks pretty normal for flowering, how old is it?
 
Hi there. Its 8 weeks old this sunday. Forgot to jot down when it showd sex. But im guessing its about 5 weeks old in flowering. 3-4 weeks to go ish.

It could be normal m8, but as this is my first grow {technically this is my 3rd. 3rd seed planted} i find it hard to tell with such a small plant if it is normal flowering yellowing or its hungry. Im thinking i could be doin with more nutes though. But its better to underfeed than over right.
But i dunno, would like a few opinions from the more experienced out there.

Cheers.
 
Anyone ?

Could this be normal, and the plant is just using up the leave as it is not an effective energy source anymore. I.e natural yellowing ?


{Just re-reading my last post there. Kronic1989, when i said
would like a few opinions from the more experienced out there.
. I didnt mean, 'thanks for the reply kronic, but i think il wait and get a different opinion from someone more experienced than you' kinda thing. I just meant more experienced than me.
Just incase you thought i was being a total douche at the end there m8. I appreicate your input bud.

Yes it is normal (but perhaps a bit early).

Your plant is transferring nitrogen from the leaves to more important parts of the plant, normal process of late flowering. Most flowering fertilizers I've seen are very low (or zero) in nitrogen after flower stretch. I've read that excessive nitrogen can slow flowering, but it is needed during the first two weeks of flower to feed the plants during stretch.

I ran a plant in a 2 liter bottle a couple of years ago, changed fertilizer and water once and added no air. Small buds, small plant. Lots of fun. Cover the bottle to keep algae from growing, but with soilless you don't need that.

For your plant just mix your fertilizer according to the per gallon or liter requirements and soak your root ball when it dries out. Make sure that you have drainage holes in the bottom of your bottle and that the plant is not sitting in water - good drainage. Mine was hydro so it sat in stagnant water a month at a time.

Thanks man. Good to know its kinda in the right tracks. Like i say was only a little experiment so i wouldnt be that gutted if anything major happend. When i transplanted it , it sliped and went in at an angle, and by that time id taped up the bottle so i couldnt see what was going on in there, i think there was like a big gap of air. I tried to striaghten it out as much as i could and packed in more soil. But a few times when i waterd early on the water just ran right down the side and out the bottom. Seems ok now though and she seems to be happy enough though lol. My drainage holes arent the best but seem to do the job.
But yeah man its been fun. Considering growing about 6 or sumthin in this way just try a few different strains in the one grow even although i may only get, im guessing just under a half each plant at the very most ?.
Also iv only a 250whps so not sure how many would be happy under that or if id be better sticking to two large plants.

But thanks again for the pointers.
