Been having some issues lately in flower room now getting worse and spreading to veg room.
Indoors, sunshine mix#4, vegged about 2 months in solo cups moved to 2gal under 1000w hps. temps are 65 at night 80 during the day. I've been doing a lot of research searching for similar pictures and at first thought mag def / pH lockout so I flushed and it seemed to improve for a couple days. Problems getting worse the leaves are all turning yellow getting brown spots and then burning/curling under the lights. Certain leaves now have a distinct hook leaf half discolored like a mosaic pattern. When researching I keep coming back to tmv or some kind of virus since a lot say tmv doesn't affect cannabis . the main reason I think its a virus is this hook leaf was only affecting one strain in flower now its affecting them in veg these twisted half discolored leaves are popping up everywhere now spreading to other strains. Theyre about 6 weeks into flower now.(7 weeks including transition) strain is thc bomb 6-9 weeks all cloned from original feminized seed . pH is 6.3-6.8 feeding with GH flora series half of recommended dose w cal mag. Tap water sat out for 24 hours. I have been alternating water/feed roughly every 3 days they need water .Pictures are from 2-3 weeks. Buds are small light and fluffy and all the yellowing/brown spots are creeping up the leaves. I'm at a loss for what to do next. Anyone got any ideas?

No idea's but I'm following to find out as well, that last picture made me cringe.
I see some little white spec's in there, any bug issues? Right on that sugar leaf in the middle picture?

Thanks for the replies. I haven't noticed any bugs, got a 30x loupe been checking the leaves for any signs of eggs or movement can't see anything but maybe I'm not looking in the right places
Could some of this be related to pot size? I have a 3gal w the same strain and there's no yellowing or browning off the leaves like that. But as for that hook leaf I'm seeing it show up in veg under t5s too can't see any bugs in there either

looks like you've got a bad case of the plant aids / hiv there... :D:D

i kid, i kid, but seriously, looks like a bad cal / mag def. going on. . you could try and foliar feed with some epson salts and see if it helps, and also add some to your nute mix.. not sure how much to mix as i have and use cal / mag plus from botaniccare and it works great ime..

btw, more then likely, the badly effected leaves won't get any better, you'll just have to keep an eye on any / all new growth to tell if they're getting any better at this point..

The off coloration and the "spinning" or "whirling" leaves are Broad mites.
No big thing really....Treat them with Forbid 4F.....look on ebay for small amounts that are not going to kill your wallet like an 8oz bottle will.

The rest is just as racer said.....bad Ca/Mg problem

How much cal-mag do you use I've been using botannicare cal-mag since week 2 at 3-5ml/L .I've never tried foliar feeding during flower for risk of burning w the 1000w & getting buds wet . this strain must be a cal/mag hog tho. if I were to try foliar feeding calmag next time how far into flower should I do it, and only with lights off or what?

i wouldn't be worried about burning them tbh.. i like to think about nature, it surely rains on buds all of the time outdoors..
man, that's a pretty heavy dose if cal / mag imo.. i think i use about 5 m/l per gallon... my ecsd atm seems to be a pretty big cal / mag whore as well.. some plants just seem to use more cal / mag then others..

Ouch, $200 for an 8oz bottle!
Shit I was hoping it wasn't bugs..
How do you treat them with this? A 1/4oz bottle be enough to foliar spray? I guess im screwed on this one at 7 weeks into flower but Ill try to get them in veg room. Could this be purchased local from a hydro shop ?

Oops my bad I meant 3-5ml per gallon haha id be going through a jug a month at that rate. Pretty disappointed in this one I've seen such good reviews and seen so many good journals with this stain but its the only one I have these problems with

oh, ok, that sounds better, lol..
i must have missed it, what strain is it m8?
and don't feel bad, my last grow i rain into the same exact problems, minus the mites, and i just throw in the towel and stopped watering them until they died.. same for the clones... then i took like a year break from growing as i got a bit paranoid and was pissed at my last grow.. shit happens, don't let it get you down too much..

Looks like Hemp Mosaic Virus to me. Probably vectored by an insect.

RNA Pro will treat but not cure this.

Expect diminished yields.

Dead plant material is a carrier of the dormant virus.

Calcium Hypochlorite solution should be used to sterilize room and equipment.

Good luck!

Ya im trying not to its abit overwhelming tho how quickly things can go from bad to worse. Its THC bomb , second time with this one I was hoping to get some nice big dense buds but doesn't look like that's gonna happen.

I've used the RNA Pro with good results, but this was started on vegetative clones rather than late flower.

IMO you have an insect vectored mosaic virus. Even the signs of magnesium deficiency hints at the possibility of root aphids. Has this been eliminated? They are a most common vector.
