Like the title says... Yellow small dots all over fan leaves, some burned edges, yellow leaves, plants feels and looks weak on lower half foliage easily falls off, curling leaves on new growth, so many problems help me out here first real grow I've spent a lump some of money on and having bad results, my past 2 not giving a crap closet cfl grows did fine and now all this :/.. Okay here is some info on my grow thus far

All feminized
3 velvet bud - seedsman seeds
1 white widow - seedsman seeds
1 nl x bb auto - world of seeds (I think)

I germinated using paper towel method, then planted in humboldt soil in cups using a 2ft 4 bulb 100 watt cfl and they starting growing great but bottom fan leaves yellowing at 2 weeks, then I transplanted to 2 gal grow bags also with humboldt mix for 2 weeks near the end of the 4 week veg mark is when I transplanted into 10 gallon grow bags with FFOF and MMM mix and put them under a 600 watt hps with a 6" hurricane fan exhausting outside with passive intake coming from under grow room door in a room 8x7x7 but only using a corner for the grow and I have a fan blowing lightly on them.. My exhaust fan cools the hood so well I put the plants pretty close within 6-8" on 600w super lumens, and one of them burned but idk if it was because of the heat or the nutes from my bad humidity it's under 20% (just ordered a humidifier) but I'm not using nutes just what was in the soil and misting them 3-5 times daily to try and raise humidity.. And the symptoms are bad and I'm really noticing some poor growth the auto flower actually detracted it's new set of leaves and started showing white hairs? I didn't realize these were supposed to be transplanted until after... ALSO I've been using tap water and phing down to 6-7 (I think anyways) with a strip test

so anyways here is some pics of the sick ladies any help on where to start would be nice.

FFOF is hot and if you use FF nute line-up..double whammy!..i recognize those leaves well.

FFOF doesn't need any nutes for 2-4 weeks in veg and FF nutes should be 1/4 to 1/2 label ONCE per week..other water should be water..i use cal-mag and superthrive EVERY water even nute water.

Looks like spider mites to me....... along with a nute problem. Are you checking pH for every drop of water that goes into the pots?

Flush, check ph and no nutes or at least 1/4 strength nutes for a while.

You burnt it.

As for the spotting that is Spider mites(at least that is how it looks to me) and you better get that under control before they cacoon your plant. Can you see them doing a little dance under the leaves? get a magnifying glass and have a good look.

Okay guys I appreciate the feedback as soon as I get home later tonight I will have a look under the leaves and around the plant... Sadly before this grow started I spotted a spider that ran out of the carpet onto the wall I vacuumed the whole room but there must be more.. What's a good method of getting rid of these lil buggers, obviously vacuum, plastic off the carpet, lay bug traps, and then what maybe a foliage spray, any reccomendations?

Looked at underside of leaves noticed nothing... Could the dots also be from nutrient burn? I didn't use nutes rh is just low so they could have picked up extra from the soil

Spidermites and spiders have no connection whatsoever, a regular spider around your plants is not going to harm them.

Okay I've been running just straight phed tap water through them and the new growth seems very very slow and on my autoflower it's like literally none at all.. I'm hoping that the growth problem is due to light burn, transplanting, low humidity, and also over fertilizing (didn't add nutes but rh was low and they coulda sucked up some soil nutes) I will take some better pics and see what you guys think tomorrow. ALSO, I check for spider mites and thrips and absolutely no sign of them so not sure what's going on, my smallest plant is 18 inches and my largest is 25 inches I'm thinking I should definitely flower soon but was hoping they would recover a little better and sprout some new healthy growth but it doesn't look like that's happening for some reason.. I just added in the humidifier today and with my extraction fan on my light dimmed down to 400w I'm running at about 70-75*f and ~40% rh if I shut the fan off it stays at about 80*f and 60% rh... So what do u guys think wait a few more days to switch to flower or do you think the switch would do them some good?

Could you also maybe take some pics in normal light? Perhaps a "better" camera with flash? Much easier to see whats wrong when light isn't all yellow :)

Here is some new pictures under better lighting of each different plant and 2 pics of one.. Now I know some of the browning is in fact either heat burn or light burn (raised 600w hps to 16" now, also added a humidifier, leaves aren't so crispy more velvety now) but I'm talking the rest of the problems it appears to have.. Tell me what you guys think.. My autoflower just stopped growing leaves but started growing white hairs, I want to switch the rest to 12/12 but would like them to recover to be able to produce some decent buds

Do you think my 20% and under humidity would have caused nutrient lockout or maybe burnt them from sucking up too much, they appear to be slowly doing maybe a tiny bit better from yesterday when I added in the humidifier now temps are 72*F and 37-40% rh
