It isn’t Cal def. the leave is symmetrical. You’re actually in week 3 of Flowering (not week 2). You can put 2-3ml/l of Organic Bloom and 1,5-2,5ml/l of PK Booster, it will stop the problem.
@ Stick: I don't measure or correct the PH, because I have a bio setup. (Ph is auto corrected by BAC tabs )
@Mrs_Larimar : thanks for the advice of the light burn , can you explain this, what do you see that indicates this ?
@ B4RNS : just this morning feeded her with 2ml bloom and 2ml of PK (and I have ordered a Cal/Mag bottle online to feed in 4 days if this didn't help) : thank you for the advice
to all: thanks for the advice , I'll keep you posted on the results
@DankGardener : thank you , I will put the lights slightly higher .
Yo people
I desperately need help
Trying to understand how to grow this strain I love amnesia haze 👌🌱my first attempt is not working properly still curing
Hello @DoctorF! Yes it looks like a Calcium deficiency, and Manganese if probably involved too. Do you always buffer your pH? In case you don't, I highly recommend to buy a pH-pen at your local growshop, pH is one of the keys to a successful yield, and a medium with a wrong pH will show random deficiencies or even worst, nutrients lockout. So grab a pH-pen, and eventually an EC-meter to better understand how strong your meals are. Double check the pH-pen calibration (with dedicated buffering solutions) and make sure every watering/feeding is in the correct pH range for soil, which is 6.2~6.5. Nothing above, nothing below! Now for your next feedings, adding some Cal/Mag or epsom salt will help, but you will still need to adjust the pH of your solution. Hope this will help, happy growing!
