Ticket-Gold leaf Amnesia haze

I’m a first time grow and I’m using MG potting soil with moisture control. unfortunately I got in a rush and didn’t do enough research on my choice of soil. It’s a 21-11-16 mix and has time release ( huge mistake I know) I’m growing amnesia haze and gold leaf. My plants have been growing very well until now. They’re still getting taller but showing signs of problems. I’m at week 9 from seed and my AH is showing some wrinkles in a few fan leaves and my GL has got some lower leaves showing brown spots. Ph level at 6.5 and I’ve checked for spider mites. Any advice?

First 3 pics. are Gold Leaf final 3 Amnesia Haze

Is it spreading from contact? If so its probably a mold in which case I’d start picking off leaves showing symptoms. If not, it is most likely a deficiency or some type of pest. Possibly even burning, it would make sense from ur Nutes but I’ve had a similar problem once and picking the leaves worked for me.

Ph i think should be higher for soil. 6.8 to 7 and it can make a difference. The heat play a big part and moisture. I spary plants with ph balanced water twice a day. To make the roots work less to get simple water to it… and i use seaweed extract. I love it. When budding i foxfarm for at leats 3 watering cycles then ph balanced seaweed extract. Look for the exhale bag. Plant will do what you want

Night high humidity. 70 to 80%. In my opion

@Soilgrowth @Idek Thanks for the replies! I’m wondering if I under watered recently. I’ve noticed no extra spreading since I found how much I should be putting on them in a watering session. Some of the fan leaves have lost some of they’re wrinkles recently too. Could this have caused some of the browning? I’ve seen recently what looks to be a couple gnats and a few fruit flies flying around also. Would a fly strip in the room be toxic? I’d also like to start flowering should I wait?

I’d recommend getting ur hands on some food grade DE, works wonders. I’ve never seen watering being the cause of spots like tht, but it can definetly be insects. Diagnosing problems can sometimes be a huge pain in the ass, but u should be able to find some helpful info
