Cool. Yeah, it was like $50 for a 500ml bottle, but the guy at the hydro store said if you only buy one thing for your outdoor grow… this is the shit you want! Plus, it’s you only use like 2ml per liter of water, so one bottle goes a looooong way.
I picked the biggest zucchini ever today, it didn’t even have one on it a few days ago so it’s not an old overripe one or anything… should be good… the plant is a real monster and has been super green and healthy looking.
Any ideas what might be causing this?
It has me a little worried. I’m seeing it on all plants… some more than others. It’s not epidemic yet, maybe 7 or 8 leaves on the worst plants, but it came on suddenly and I didn’t see it last year at all. I’m in the 2nd week of flower.
If you’re not under-watered, could be a pH thing
I dunno the first thing about raising pot but other plants “burn” like this in my garden from time to time
Thanks. I have an electronic pH meter and I seem to be in the normal range. I did add a 0-1-2 “bloom booster” phosphate amendment about a week ago, but in almost trace amount and this doesn’t look like nute burn.
You may be right about under watering though. It kind of looks like leaf burn. I water every night, but temps have been 100+F for over a month straight now, so maybe it’s still not enough water.
It’s the heat, man
They’re probably well fed and all, but with those temps, some nutrients are not absorbed well by the plant
Then you put water to compensate for the heat and they end up absorbing more of other nutrients, so they end up like that, looking like they’re in a lack and excess at the same time
I fucking hate the heat to grow weed, after this last batch I’ll be so happy to turn it all off for the summer.
So if you have to water more, should you also be adding more nutrients so it doesn’t get diluted? Serious question, since I add water but still see burn (I have a brown thumb)
I don’t think so. These nutes have a limit on how much you should give the plant. What happens is that you put the nutes, the water dries quickly, the nutes stay in the soil, you put more water with nutes, you see what happens? You overfeed them easily. Each plant is a different case, some can take more, others, not so much.
Even weed is like that, some plants will eat a lot and drink a lot of water, others not so much
I always check the weight on the vase to see how humid the soil is, sometimes I’ll skip watering it altogether for a day. I keep a mental note of what I gave to the plants, but some of them will need something different, you see the leaves yellowing on mid-flowering, for example, you put some magnesium and nitrogen, but only on those with the yellowing
That’s what I was thinking… just the abnormal amount and duration of heat we’re getting this summer. Not much I can do about that but hope it starts cooling down some soon. Last year it was the crazy winds we had and this year the crazy heat. Man, outdoors growing is just a bitch.
Mutherfukking leaf hoppers are becoming a problem. I’m seeing more and more.didn’t have any last year. Apparently they become a problem during really Dry and hot spells. These little things are stealthy as fukk and are nearly impossible to catch. When you get a few inches from them they dance around to the other side of the leaf. Too late in the game to use neem oil.
They suggesting planting a couple tomato plants along the weed
Tomato is the only thing insects love more than weed
Haven’t done an update on my crop in some time. All gals have been in flower now for 2-3 weeks.
The thing I’m noticing is that the plants getting the least sun are faring the best. They are the greenest, bushiest, healthiest and were first to hit flower. I suppose the triple digit heat streak we suffered through had a lot to do with that. Because of the weight of the plants it was simply infeasible rotating their position. Here are the one’s getting the least sun.
The plants getting the brunt of the sun had a lot of foliage die off, didn’t bush as much and started flower later. They are also twice as tall.
The autos are as dependable as ever. Doesn’t seem to matter to them where they sit.
All in all, I can’t complain. The heat was outside of my control and there were some times where I thought I would lose a few girls. Things are cooling a bit now and of course the days are getting shorter, so I think all will survive and prosper to varying degrees. I’m going to hold off on harvest this year at least until mid October. Gotta have patience to get those colorful buds.
Dude, your plants need magnesium and possibly calcium ASAP
Get some Biobizz Grow (it has high MG an low N)
Mine were looking like that and if you don’t act, the buds will come out thin and airy with low potency
I’ll see if the hydro shop has it or something similar.
Anything that has Mg in it, but the Biobizz is soft on the plants.
You might use Epson salt, I believe that’s organic too, like the biobizz
I have a shit load of Epson salt leftover from the super soil build. Does it typically have both mag and calcium in it? I don’t have the original containers, so I can’t read the label.
The epsom salts are magnesium sulfate, it just has magnesium in it.
Does it look to you like I need magnesium? Up until now I wasn’t tripping to much on the yellowing leaf die off. I just figured it was the heat. Rancid is getting me paranoid, man.
Rancid is probably right, are your stems purple or purpling? Your grow shop probably has this…
It’s very common to have Mg deficiencies when flowering starts and if it’s too hot, it’s almost certain
I suggested the Epson salts because I’ve seen other people using them on another site and it’s usually a very good solution for quick Mg feeding
