First time grower looking for some advice.
I’m growing x2 auto flowers (same strain) in 3 gal pots of coco coir/perlite 70/30 mix. Once the seeds popped I planted them both into their final pots. I’ll probably pot up next time as I struggled a bit with the watering amounts which I believe stunted them.
I’m on day 26 today since sprouting and below are some pics. They’ve both been watered with the same frequency and feeds but one is clearly lagging. I’m a bit concerned with the smaller one as it looks to be showing some deficiencies. I’ve checked the pic chart and to me it looks like a zinc deficiency? I’ve been logging all my feeds, environmental variables etc so hopefully that will help diagnose the issue. One thing to note is the pH runoff has been higher for both but I’ve ignored it as I keep reading not to chase pH run off in coco. EC run off has been the same or similar.
