I may need to water more frequently but with less amount at a single time to prevent water run off and excess build up in the bottom of the pots. Started LST to hopefully cause a shorter plant height due to growing constraints. I plan on topping as soon as they reach 6 nodes.
@capricious from the way they are yellowing I would say its lacking in iron which can be corrected by spraying with chelated iron
I would reccomend a regular feeding of Calmag as well mate
You are in a early stage of your grow, and its no big damage, It may took not so nice, but its way better than having an excess. Plants come back just continue feeding . Ian around 3 weeks she should look great again
