Before you add any more nutes, which I really don't think you need, treat them for mites. I had some Super Lemon Haze and Platinum that were doing the same thing. Sprayed with green clean and took all the munched on leaves off. They made a full recovery and started growing with vigor after 5 days. You got bugs dude. All the other growth looks healthy; no signs of nute def, light burn, wind burn, etc.

I appreciate it, have green cleaner and mighty wash. I am unable to get eagle 20 in California. I will post update. Thanks

You have no reason to use E20 here.

Update. I want to start by saying thank everyone of all the advice. I went back over all my plants and haven't found a single leaf eating bug. I do have fungus gnats pretty bad and have been treating with BTi and yellow cards. I went out and bought sand to top my coco mix with. Fans are on low and about 2 feet away from plants. I used my temp gun and hit leaf Temps of 76 degrees. I sprayed the plants with mighty wash and a follow up spray with mycotrol. Feed them with more calories mag 150 more ppm. I will keep you all posted and provide pictures. Thanks again all of you

Try spinosad instead. I recently switched to that and it's working well for me. No Bt formulation has been effective in my case. That said, is the Mycotrol labeled for anything like the FGs? If so, then I'd say you're not using an effective dose.

I also agree with stonestacker re: the calcium.

Update: I thought it might have been windburn but yesterday I found an ungodly amount of russet mites. The mycotrol and big time exterminator isn't holding them back as well as I thought. I mulling the idea of using avid and forbid for my first time. I lollipops high and only have 1 foot of canopy. I do not think it would be wise to try the organic route at this time. Would love some advice

Ok, it's time for you to go to caregiverken's thread on russet mites, read through the WHOLE THING. IIRC, your girls are now in flower, and if that's the case I personally can't advocate using either of those products.

Update: the russet mites have been destroyed and when I say destroyed I mean not a single one alive. I went through all my plants and didn't find any alive. A lot of dead exploded bugs. I know it's to good to be true because there has to be at least a few hiding. I didn't have to go nuclear either. 8 did 6 sprays 3x mycotrol with Monterey as a booster and 3x big time exterminator. All organic no resistance. It take 3 days to start really working but I am seriously inpressed. I would recommend this coarse of action and u can use until the day of harvest. I will continue spraying every third day. It also kills the eggs. Thanks guys and gals

Hello fellow thcfarmers. I was wondering if I could please get some help on a few issues.

I am running

Coco coir/perlite mix 50/50
Gh nutrients 6 ml micro 9 ml bloom 750 ppm
Cal mag 2 ml gallon
Feed every other day 1 to 1.5 gals
3 gallon cloth pots
1000w gavitas

Problem started week 2 flower
I believe it's potassium deficiency or mag calcium deficiency cause k deficiency

Had no issues with leaves until I lollipop plants and issues developed in a day

I do 20 % run off

Have fun gas gnats and am correcting with mosquito dunks.

No bugs I have checked with 50x microscope

PH 5.8 checked with multiple meters. I'm sure I am not over watering. This issue had happened with every grow I have had and am unable to fix it. I am at your mercy. Thanks

so what made it go from no bugs to an ungodly amount of russets. How'd you miss them before what made the difference in spoting them?

They were hiding real well under the stem of the leaf. They like to lay eggs around those locations. When I lollipoped high. They were forced to come out and migrate upward. They go into overdrive when you start to show flowers. One russet mite can lay 30 eggs a day. They multiply so fast and are so hard to spot. I'm using a 30 to 100 x USB microscope. These things are devious to say the least. The funny thing is I got no tacoing of leaves this time only deficiencies that looked like k or windburn. I knew when I saw the flowers start dying back on the bottom of the. An opt and the hairs turning orange I knew for sure.

Seamaiden thanks for the post on the mites. I read it all. I was quick to want to go nuclear. I'm glad I didnt. It's hard as growers to slow down evaluate and ot to rush into things. A lesson learned

Get a giant flashlight and a magnifying glass, turn off your grow light and lay under or sit near the plants and shine the spotlight while using the magnifying glass and you might see them. Diatomateous earth in a garden duster will take them out, wear a respirator and turn off your filter fan b4 you dust, close the doors and dont let anyone breathe the dust if you use a duster.
