GSC First grow

seems to be a slight calcium deficiency by the looks of it

Thank you i will See what i can do about it

just curious why do you think it’s cal mag issue?

I think its because of the light green to yellow colored spotting, it could be observed as a calcium deficiency. The stems and veins seem to be okay so you can rule out magnesium or potassium. It looks pretty localized so it could even be genetic. Best way to find out is to test the runoff from the plant or the water youre giving her. Fluxations in pH change can definitely alter the efficiency of nutrient intake.

not seeing what you are seeing, anyway, I’m new at this and just trying to learn, I don’t see yellow can you show me which picture and leaf? trying to learn what it’s should look like. 👍

Its the second picture, broad fan leaf. Has some light green spots. This is quite an early catch. Those spots are generally around the edges of the lead but can occur as a polka dot pattern as well.

Oh K got it thanks 👊

what is the light distance to the plant ?

35cm and Its on 40% Power Right now

u can switch to flower , I would do some defoliation & wait a week & switch . u want to open up the canopy so u have some airflow. plants will stretch when u flip to flower .

no I'd wait till there about 3 ft tall however if this is a photo u might be ready for topping just do it all the energy goes to your side branches And you'll have all kinds of tops cause after u top then u can top your tops .but hey they look healthy

okay Thanks for Your reply i will definitely wait than

they will double in height from veg to flower so half the height of the available space. you can always bend them around though.

brown tips and margins would make me think potassium (K) deficiency. that plant and the one in lower left also appear to have Nitrogen (N) deficiency
