Autoflower number 2, all tips are welcomed guys 👍❤️

Hey guys some leafs going weird looking and light grey bit sucked in

Strain and age?

Its either ak47 or skunk i forgot to mark the pots as i got 2 autoflowers

And also just over a month

Looks like insect bites.
Are you checking the ph when you feed?

Yes ive been keeping my ph at exactly 7 for both my autos and one is growing beautifully compared to this one

Too alkaline. Your plant can’t access all the nutrients. You need to drop the ph to 6.1-6.3.

My first three plants, i did not monitor this. Since i changed my practice the difference is dramatic. My fourth girl is a beast now and growing big funky colas.

But one autoflower is growing beautifully using 7.0ph

Its surviving but it would be thriving if it could have full access to nutrition. Been there done that so I’m just saying if you want to improve your yield you need to drop the ph.
