Help

So I'll give a brief backdrop on my scenario to give some contributing factors to what may be wrong. I finished a full grow throw harvest with a 150w how in a small closet, there were 8 plants each in 1 gallon pots and I got a decent yield with my grow space and the quality was top shelf,, after harvesting I splashed some veg bites and sent them to re veg blag blah blah, after putting out decent new growth I took 4 of my best and transplanted into big totes, not huge but a decently good size and moved them in to an outdoor grow room,, I also ok them under a 1000w how and the size of the room there in is about 4x4 with an in exhaust blowing fresh (cold air) that i had to shut off to too cold ass temps and an out exhaust running through a carbon filter and my hood to exhaust needed heat,, it took a couple days to get the temp down stable and now have it sitting at 75 degrees 2 feet under my hps with the exhaust fan on low to ensure the room temp stays stable.. Now here's to my problem, everything was running great, bushy growth from the sides and a great color green with noticible new colas popping everywhere due to the (monstercropping) or revegging I sent them through and they also looked healthy, after 2 nights of cold temps, at least that's what I think it was, caused the main colas to start limping and putting out light green growth..

My theories are..

the cold affected them

They need more nutes because of the drastic transplant into bigger pit

To much light (kicking it down to 600w lowers temps to 65 in the day and lower at night, and I don't want to draw any more electricity with adding a space heater, that's why I have it settled at 1000w (I originally had a metal halide but like a dipshit retired it without slowing a cool down period and busted it so I'm stuck with my hps)

Growing to fast (read this happens sometimes?) Was thinking of pruning up old growth and just leaving main colas plus some fans IS THIS SMART?

Humidity, the humidity is more often than not low but can keep it around 35-40 most times

Sadly I don't have any before pictures of the new transplants good growth, just ones of the bad new growth and again sadly, the pics are under hps so you won't be able to see the light green but the limpness is noticeable. The last picture is of my inside plants new colas growth, this is what new growth looked like on the transplanted ones before things started looking south and is what I'm aiming to get back too.

I know I asked a lot of questions but any and all help is greatly appreciated to get my babies back on track!!

If you just transplanted them, it could be something with the new soil. Did you already start feeding them more? If you're growing in soil then you probably won't need to feed the plants for a while.

It's the same medium with no added nutrients or anything except healthy bacteria I.E michroyza,, I add liquid nutes myself to the soil so definitely is going to need to maintain a feeding schedule to make sure I don't have problems, Feed water water is the usual formula but I normally water 3 times before hitting with a feed,, when I transplanted I hit them with transplanting nutes and then just water for a week then veg nutes then water for a week and now this is where I'm at, if anything I would think it would be a lack of nutrients since there is no added nutrients in my soil to begin with and I just added more growing space

Its in a Peat moss, perlite, soiless mix

Your mix is soilless so you need to be checking your ph. Do you know what the ph is of your water going in?

Looks to me like the roots aren't happy or like your medium isn't nearly wet enough (it looks dry to me). Drench those things with a PH balanced solution of nutrients and quit giving them so much plain water. You are probably just flushing out all the available nutrients.

Sorry forgot to mention I ph test my water every water and I keep it 6.5 early on in grow and then 7.0 rest of grow

I have acid kits, so that is not the issue,, thank you for advising more water, just the topsoil is dry due to the lights, 2 inches down is still moist though and do not want to flood my plants

I'm pretty sure that is to high for soiless unless peat moss is special and I don't know about it,. I think should be around 5.5 - 6.2 like most other soiless mediums

And I don't want to be giving them nutes every water because that will lead to some nasty issues, chemicals will build up so much it will require big flushes to get all that nast out and if I don't get it out my plants will smoke shitty and possibly have bad chem burns, I also can't flush in this room right now until harvest so I need to make sure my chemical build up isn't to harsh

What is ph last time you watered?

And sorry for above, I meant I keep it 6.0 for early growth and 6.5 for when it's really putting out growth, 7.0 is what it comes out my tap at,, early early development id do 5.5-6.0 but i havent done that for a little,, ill check on it lowering the ph a bit helps

Might want to still with soil then. Soiless mediums are basically a sponge full of the available nutrients you provide the plants. All you are doing with plain water is diluting and washing out whats in there to the point where they will starve. If you don't want a ton of nutrients stick to consistent low PPM nutrient filled watering and occasional flushes. But I think even that is overkill.

If you let your medium dry out they are going to die as well. It needs to be kept moist at minimum

Like I said right now it's moist two inches below the topsoil and the tub goes down a ways with what I can see is still moist,, it is pretty cold and tight packed,, I'm gonna hit with some ph'd water,, add nutes or no? Have only gave plain water once in between feeds this time which means the runoff is still saturated with nutes(can visibly see this when I water) this will only add more nutes sponges into the medium, normally water one more time before hitting with nutes,, it doesn't get dry, I make sure to keep it moist I just keep a constant recycling of old nutes and new ones

And the ph was 6.5 to 6.8 or so last water

This is my soiless coco grow. They have never seen plain water in their life and I water them every day, sometimes every other day with nutrients PH from 5.8-6.0. If I think they are getting to much nutrients I cut the amount down for a feed or two.

Nice man!

How many plants there? And how much do you water about each day?

If those were my plants.I would flush them with nutrient water at a 6.2 PH. I mean drench them so that an extra gallon or two of the solution drains out the bottom on each pot to get the medium down to an acceptable PH level, but not create a massive PH swing from 6.5. In the watering on the days proceeding that that I would take it down to 5..8- 6.0 and keep it there. But that's just me

8 plants. I usually give them about .5 - 1.5 gallons a day, it really depends. I barely try to lift each tub and I can tell if its saturated with solution or not from the weight. Based on how light it feels is how much solution it gets.
