Hi Everyone,

A newbie here, I’m not sure if this issue is heat stress or nutrient deficiency or just me been paranoid...

Light 600w hps dimmable ( using 400w)
Soil is canna pro with some extra perlite
Room is aprox 1 sq meter
Autoflower grapefruit from 420fastbud ( the 3 ones)
The little is autoflower big devil (something) from a Spanish bank .
All of them germinated in jiffy and moved in pot as the root appears out of the jiffy. (3 days basically)
Look forward to your help.
Thanks in advance.
Mat

Plant looks pretty good ... single finger leaf will go bye bye over time . Some leaf show minor “ blemishes “ from time to time , nothing overly to be concerned unless it “ goes plant wide “.

I say keep her happy as is and continue what you are doing , overthinking plants ( especially autos ) often lead to disaster.
Autos are simple plug and play , so much so , a good bagged soil mix will run them entirely without adding any bottled crap.

She looks Indy so , she will ( should ) throw large fat fans as she grows.

just not the most photogenic plants but they are healthy enough
looks like coco and perlite i would suggest advanced nutrients PH perfect it's terrible in flower but the grow A+B give me perfect results everytime i never change the PH and i never have any deficiencies
yours does
what i found with PHing is i never started doing things right or wrong i just at times was tired and dripped too much in or smoked a spliff and forgot i've already PHed adding more remove the need with chelated chemicals and you won't get any deficiencies, with all nutrients available heat stress becomes faster absorbtion of feed

after looking closely on the 2nd pic no deficiencies quite strong looking for its age you're missing a bit of leaf, unlikely to have been bitten off given it's positioning i think that may be nute burn i'd suggest 1ml per ml for a few days then 1.5ml assuming you're using 2-4

the discolouration at the bottom of the photo is something to consider since you have signs of nute burn it's probably nute burn within the leaf or if its a deficiency alongside nute burn arre you using a good measuring apparatus to make sure you don't have more A than B etc?

edit: too much nutrient in the water and bad PH level

i think this leaf had been damaged young and grown healthy since

You do not need nutrients made specific for coco. Or any medium.

You adjust the nutrient solution for the medium by adjusting the level of pH of the mixture before giving it to the plants.
