Calcium or roots trouble? Hello happy grower,
New week and new trouble but on the second plant.
Those brown dots appear today.
Is it a cal/mag defficiency or roots trouble? I will check roots tonight.
Thank you forward for your advise!

Discolored, burnt and curled up tips on higher leaves Several symptoms, always on tips of higher leaves : they are discolored/burnt or burnt/curled up. LED @40cm (deemed 70% of 300W) and I just gave them the 2nd flowering feeding, 4 days after first one (pots were very light). I was planing to start compost tea... What should I do ?
