3 weeks in to flower leaves canoeing NEED SOME GOOD ADVICE

[Jclee133]

Second time outdoor grower, ladies are 3-4 weeks into flower on our diesels we've been noticing since veg that the leaves are canoeing inward. They are huge plants in 65 gallon pots. I live in lower nor cal so it is very hot and dry. We've added cal mag when we first started noticing it in veg and it seemed to help the leaves curling in but still worried about the canoeing. Buds are stacking like crazy did a top dress of primal harvest feed age old bloom bi-weekly and compost tea occasionally.
If anyone can give me some insight on the canoeing and if it is something to be of great concern or just heat stress which iv read can be a cause. Please help I'm a very concerned mama

View from the top. Can you spy my lil peace sign. I'm 5'11 if that can help you picture how ginormous these plants are for their little pots.

Sometimes leaves do this when trying to dissipate moisture. Other times it could be a sign of somesort of lockout or toxicity.

plants look nice, good luck rest of the season

That's a sign that ambient temps are too high and they are transpiring.

These pots are on top of lava rock and need water more often then our pots on dirt. Water drains out quickly could this be the cause of the canoeing? Seems to be effecting the higher leaves the most could the upper leaves not be getting enough water? And will this effect our flowers.

Don't think it's any over feeding been doing mostly organic (age old bloom which I just discovered isn't organic)
What would cause toxicity? We constantly check our ph and adjust our water.

Leaves we're canoeing in and tips were curling under so we were advised to add cal mag which has definitely helped the tips curling under but (mostly on the top colas) the leaves are still canoeing. Could it be from the heat?

Our plants are doing amazing and the buds are stacking like crazy. May be a little over paranoid but these ladies are my everything! Thanks for the help

Cal mag would help but it could also make the problem worse if the calcium levels in the soil went too high and locked out mag and caused a deficiency. The cupping could very well be that and the imbalance could be the issue. I have seen similar cupping with this type of lockout

I would say its a little too much food. Also, age old is very strong for "organics.". Are you using any other supplements. Some kelp/seaweed and molasses will improve their health and look. Even better would be a compost tea with both those things in it. Just remember that age old isn't a complete nutrient.

I wouldn't use any more than 1 tablespoon per gallon.

And I never adjust my water. In the past, I have only gotten into trouble doing that.

It could be russet mites. Have you looked at your leaves and petioles with a scope?

Some good advice? Scratch and sniff before you lick and poke.

Too much ferts... The tips are showing burn. My experience is certain types of nitrogen do this to thai plants{leaves curl up at tips} i have grown many times. Like most things it is not just one factor i am sure heat/transpiration rates play a factor as to making the planties show signs of toxicity quickly.
As well in my experience the east coast sour diesel clone i have loves ferts in veg and not so much in flower{ i keep ppm lower then other strains}

I've been feeding them a worm casting molasses kelp and fish powder tea once a week along with the age old bloom every 2 weeks I'm only having trouble really with my diesels blue dreams look good. Also have had the scope out....didn't see any russet mites

More pics...leaves are continuing to burn and die off. Contemplating doing a flush possibly watering with a rinse like clearex. Hope the unhealthy leaves won't effect our outcome too bad buds look healthy and still stackin

maybe dial the teas strength back a bit after a couple good flushes....Is your fish powder heavy in N

 

[mossyoakle]

That's the age old. A friend told me to be careful with that stuff, "it will burn the sh*t out of em"

looks like over fert to me too along with some of your climate issues. I would certainly go with straight water for a short time period before introducing nutrients again and start off slowly again like 1/4 strength and then 1/2 and so on. sounds like you're close to harvest anyways so your likely going to be on straight water until you harvest
