the strain is PPP, and yeah i put them on 12/12 a few weeks ago... its hard to see what i mean in the picture.. ive grown plants before... the leaves do look a little odd the ones right at the top smaller more compact more heavy looking and some of them have little breaks in the leaf.. defo something is a little off... i thought it might be back from where they got overwaterd but ive had them on hydrogen peroxide for 2 weeks in the nute water... its not over fert and its not PH i think i've had that happen in the past.... i still think its some kind of oxygen deficiency...
the pre flowers only just started to show last few days the white pistils.. but the top new leaves have not looked right.. i had some free seeds with my order planted them too but their much younger... they are showing the same symptoms the leaves just looked small compact and heavy and THIN like the top of the plant has a Medusa type thing going on...
