Interesting tip discolouration

VincenzioVonHook · Sep 9, 2022

So this amnesia auto (week 5) has been doing this ever since it pre flowered about a week and a half ago. New tips have a bright green/yellow hue and as they mature it colours up fine.

Soil pH (slurry) was 6.6, probe was 6.8 but I wouldn't bank on that. input is just tap water at 200ppm/7.5ph. Feed is 2 tbsp of 8:4:10 slow release. Medium is 50% yard dirt, 30% Coco and 20% perlite with some vermicompost (5L per 20L mix).

Not too worried as by the time they mature they color is fine, just wondering if anyone else has had a similar discoloration? If anyone's wondering the little brown specs on the leaves are medium from transplant still lol. I'm lazy.

I love it when it does that. You must have your watering and feeding just right.

It's the first time I've ever seen it, so it might be lol. It's not often I water or feed right haha.

I’m guessing this is where you turned the light up for flower? Looks like light stress.

nah its an auto. It's at like 38k lux atm, and the taller plant is at around 50k lux. That's what I thought it was TBH. I did recently drop lighting hours down to 17 (from 20) though as they were both getting a bit droopy two or so hours before lights out. They seem to be a lot happier than they were when lights go out, but i might be way off here.

The amnesia is roughly 60cm from the light, the gatorslade is around 48cm away. Light dimmed down to 70% (240w quantum board).

VincenzioVonHook · Sep 9, 2022

The gatorslade beside it is going well and showing no issues despite being a bit closer to the light, but each strain could tolerate light at different capacities.

it would be interesting if I lowered the lights intensity and it clears up though.

The only thing that has me thinking that is location. It's all up top. Some do take the light a lot better than others. That's what got me into just 1 plant in my 4x4. Less to please. However I'm watering a 5gal more often than I thought I would. When I had 4 pots in there, it wasn't needed as often.

I'd love to do a single beast of a photoperiod tbh...next run is a planned chemdog #4 fem in an 80x80. The 12/12 schedule is a blessing for summer. I struggled hard earlier on this year due to temps.

I've just gotta get used to not staggering plants and popping seeds in the same when they go off into flower. Just an excuse to set up another tent lol.

It would have also been nice to have the space available to open up the plant a bit instead of defoliating. I could have filled the width of the tent with one plant and had a far more level canopy. Wouldn't be worth it with only 4 weeks veg and an auto tho.

I love just tending to 1 plant. I need to go to a much bigger pot next round tho. Thinking 16gal.

I’m running 12/12 currently at night to evade as many issues as I can without skipping a beat. Low humidity is my enemy this time. I keep another tent with clones/moms in it to take cuts from. However I may be flowering a couple of them out & making room for more. I have a pack of high Mac f2’s I been dying to pop since I got em.

Ill probs give that a try over summer. Apparently having a cooler dark period is beneficial, but I can't see it being too beneficial if the lights on temps are getting well over 40c lol. It hardly ever gets under 27-28c in my room even at night in summer. It's hell. It will be 32-33c lights on/off if I go 12/12 from 6pm-6am. Probs better than 38-40c day and 28-30c night. Luckily, I've got a month or two before it gets too warm here to wrap my head around summer again.

Once I hit flower I kick that ac on.. however this round I have it off for now. Keeps my humidity up around 59%. Ac goes on low at lights off to keep rh from spiking.

I have the same shit happen with my organic shit sometimes. I was trying to figure it out for awhile now, and think I might be getting closer, :lol:

.

My thought now is that's a deficiency, and my guess right now is K. But this is just this stoners theory for now.

I've noticed that turning down the light intensity helps, which also says deficiency to me. And K deficiency makes sense to me with my situation. The K gets locked out of my soil sometimes from too much Ca, and it doesn't help my water already has plenty Ca. This is a good thread though. I might learn something, :bigjoint:

I've gotta get a better AC. It basically won't work if the ambient is over 32c. If the ambient is 28c and 70%, it will come down to 25-26 and 55-60% pretty quickly, but once the temp gets over 31-32c, it just acts like a mild dehumidifier. Good old partables. Doesn't help that my room is 20m2 and the walk in attached to it is 4m2 as well. So 24m2, it just doesn't cut the mustard at 12000 BTU.

Tell me about it. My RH is under 10% right now. Oh shit, that makes me think burn now, :lol:

I was gunna turn the light down a bit tonight and see how we go. It does seem like it's possibly pushing the plant a bit too hard and forcing it to eat at a rate it just can't keep up with. The DLI was well over 50 until I dimmed the light three days ago. It could still be runoff from that. I'm at about 40 now.

And here I was thinking that 35% lately has been a bit dry for veg. I'm sitting at 50% in room now, and around 45% in the tent which is pretty good at 24c.

Do you use salts or organics?

At the moment im using this. 2tbsp of 8:4:10 salts per pot lol..nothing but $3.50 quality here.

There is a wee bit of vermicompost in there. It's 50% yard dirt, 30% Coco and 20% perlite with 5L/30L vermicompost mixed in and 2 tbsp of slow release per pot.

I went three tbsp with the current one in flower and it burned a bit and got some calcium lockout on the top leaves..

"A bit" more like a lot.

My conclusion is that 3tbsp is a bit much for a 3 gal pot lol.

Well 10% or less isn't ideal at all, but I say fuck it.
