Help Please , what is happening to my leaves?

Probably to high light intensity, lights to close. They don't need much light to flourish in veg.

Thanks. That’s what I suspected. Do you think it could possibly be a mag or cal deficiency too??

Lights stress will typically show Mg and K def.

Thank you

Looks like Zn def. Quite an easy one to recognise as the top leaves show interveinal chlorosis that starts at the leave edges.

Question is now, is it a case of not enough or something else antagonising it.

A wee bit more info, media, feeding habits, how big the pot is how more water and how often

Light stress

If it’s new new. Probably light. Another possibility is could be cal/mag. Check your tds every feeding. Cal/mag takes 4-6 weeks to show a deficiency after it’s already started. Recommend great white rooting powder as to help roots absorb maximum nutes and grow very robust. Good shit. For all your smoke gear head to savsmokes.com. Gonna need a nice bong and some hemp wick to enjoy your buds once cured.

It’s not calmag, or at least not Ca. Ca deficiency is usually brown necrotic spots on the leaves. It could be Mg, P or K, question is, is it a deficiency to a lockout, and if a lockout, why? More info on soil, nutes, watering, and light needed
