hi farmers, my gals r in 1st week of flowering what kind of diease is this?

[Ras_d]

Please take a look at the gals.. currently my ac is not working so the tent tempreture is 31-32 degrees celcius during the day at the peak... could this be one of the reason? this happens when they r in vegetative period

thanks...

possible P excess i'd say, i think root rot can also create rather similar symptom note sure tho'

search google for "jorges cervantes excess and deficiencies chart" full size, image is too large for me too link it here as reference, text on it won't be readable.

what medium do you use (soil, coco, mix, other)? (brand, line or composition)
what have you been feeding this far ?
wha's you watering pratice ? (frequency, amount, volume of pots)

I just feed the gals with compost tea with 70g of chicken manure 70g of worm casting, 70g of fish meal + 70 ml of molasses..

these 4 gals r in 3 gallon pots i feed them with 1.5 litres water when its dry, i used to fee them with 2 litres of water which i know i might feed too much, the water is ro water with ph level around 6.1

the soil is coco coir with dirt in the middle, 2 of the gals now have a very light bucket if you know what i mean..

Plus these gals r facing some little black flies attack which i cannot control, then i decided to switch to flower right away.

cheers

Your soil is releasing too many locked nutrients. Like Phosphorus or there is too much in the soil. She is trying to get rid of the excess she is consuming and shows as crystallized leaf burn. Which your leafs are showing the symptoms of Phosphorus excess.

 

[Bdubs]

Microbial teas should only be used every so often and not every time. Once every 2 weeks or more like 3-4 in summer (we run summer temps on these girls all day). The microbial activity in your soil is bonkers and is releasing all the positive ions with the acids your introducing.
I don’t use teas. I am a noob. Only speculating but pretty sure if you are not using the microbial teas correctly, it has a negative impact. Molasses can stunt your growth too so be careful how often you blast her with it.
I could be way off base.

 

[Bdubs]

Phosphorus must be unlocked from the soil. The plant roots excrete acids that help break things down and make nutrients available. When you add your microbial tea, it has acids from its mix and that help break down the outer molecular wall of positive ions and then makes Phosphorus (positive Ion, locked to the soil) available to the plant for absorbing. So, because P needs unlocked, you have an issue on the soil side most likely. Thats what brought me to say you have an overactive soil from the tea. If you are using the tea all the time.

I have had this happen to me in hydro, mid to late flower. It was excess of Phosphorus. I had root rot to a degree. But the Ph at the time was creeping high just above 6.8-7ph iirc and I had bumped the P and K nutrients before the symptoms. I was burning from Phosphorus in excess. I corrected the Ph and reduced the P and K and it corrected/stopped progression.

And those temps..that’s hot. Cooking buds and taxing roots. 80 tops. Above 80f you are going to see foxtailing, heat stress and hot soil temps, a lot more plant eating/drinking and more frequent watering. She is chugging water and forced to eat. And P is in excess so it’s burning it and pushing it out through old leafs.

pal, how to unlock the Phosphorus from the soil... i'm a newbie, I've turned my ac in the living room on to bring down the tempreture under 80 f now...

It would be nice if u break this down step by step, as the gals enter the flowering stage, time is running out...

thanks alot for your help...

cheers...
