First grow, unknown shenanigans

Hello people, I'm a first time grower and I was hoping for some advice with these punks.

The last 2 waters I have only used PHd water with CalMag, as I was advised I had over fed with nutes and had a calcium defiency when I last post.

This seemed to work initially, however they are now flexing like this....
Leaves yellowing
Curling downwards
2 bottom leaves on one plant seem to have died and bent right up on themselves
Slightly distorted growth / twisting leaves
Burnt tips
Not respecting my efforts

After doing a little research I deduced that it could possibly be potassium defiency or a heat problem. They have a fan on them and it's usually around 25C in there though.

Thanks in advance for any advice / ninja skills as to how I can help the little bastards. It seems like everything is their enemy haha.

Cheers

What is the source of your water? If your soil is decent, it will buffer the water, in fact adding ph up/down to a soil grow's water can f up your soil. I doubt anything this young in decent soil will have cal/mag or any nute deficiencies for that matter. My first grow I didn't add nutes till 20 something days as advised from a very experienced grower. I'm 30 some-odd days into my second grow and haven't applied a single nute and they are happy as hell.

My advice would be to stop applying anything other than water and don't screw with your water if it is tap or well. Not do be a dick but stop resenting and bitching about your plants. They aren't responding well to your efforts because your efforts are killing them. Structurally they look good so it seems your lighting is solid and they don't look drowned which is great, you'd be surprised at how many people simply kill their plants from overwatering. Less is more so be patient, water them without screwing with the water and let them recover. When you do water, water them till run-off and stop. Then wait for at least 3 days before even lifting the pot to see if it's light. They might look worse before they get better due to the jacked nutted-up soil but give it time.

Looks like heat. And maybe under watering. How old are they? How often do you water? What ligt are you using? And how close are the lights. Is the fan directly on them or circulating?

I was thinking that too man, soil seems very dry but thought maybe he shot just before watering at their driest.

First off, I don't resent them haha. It was a little humour. This is my first grow so I am aware they are responding to something I have or haven't done correctly. They are about 5 weeks old.
3 feminized seeds (Royal Queen Seeds - Special Kush #1) under 2 85w 6400k and 1 250w 2400k CFL lights. 3-4 inches. Medium = Coco coir with perlite. Light cycle = 18/6. PHing tap water around 6.0. The fan is oscillating.

I have watered twice in the last week till water was running off. This amount as I thought they were quite small compared to the pots. Pictures were taken around 6 hours ago I last watered on Sunday.

I did start using these nutes and this shedule after around 2.5 weeks however like I said I have now just watered with PHd tap water and CalMag as advised by others.

Nice one for any advice

***And yes I have been using PH up/ down

Your pH is too high home boy! bring it down too 5.5-5.7. it's coco not soil. you have to control your pH in coco it's just like hydro...Hydro nutes and ph.
They are probably underfeed, either over or underwatered, and your ph is probaby way fucked

Yeah I probably should've mentioned all that stuff at the start of this post also...apologies ha.

Okay so now you guys know its coco should I....

1. Lower PH
2. start adding nutes again??

Thanks

So ya I re

Coco doesn't hold onto much. flush it out get your pH right. then mix you up some nutes for early veg+calmag.
Idk how big your pots are but you don't want them to dry out. once a day or every other day probably.

Yeah bro in my first post I assumed it was soil.

No qualms slow grow, I forgot to include that important info haha.

Okay I'll flush, lower PH, correct the ratio for nutes+ calmag and hope.

I'll see how I go in a week and post an update. I appreciate the advice.

Nice one

No problem! it's a reall pain in the ass if it gets out of hand. make sure you have a pH pen and you calibrate it too! often!
