Please Help Save These Girls!
Pale Psychosisters & Cream Caramels

My second grow in my new space hasn't gone too well so far and really want to bring them back to health before 12/12.

I cooked the roots early on with underfloor heating issues. I have now isolated the room but I think this may've prevented nute uptake, I got yellowing so thought they MUST be hungry so fed 2ml of Oldtimer Grow and burnt them. Lost a few lower fan leaves.

I'm in Plagron Batmix so thought they should have had plenty of food for vegging without me having to add any so I was very cagey about feeding. I didn't riddle the Batmix (didn't have time and to riddle a bag of this stuff and break down all the lumps, twigs and timber would take an hour or 2 I reckon with my little sieve!) but can't imagine this is the problem and I did try and break it up by hand and with a trowel.

I potted up a few days ago to 3.5lt using Batmix and PM Granules (is it wise to mix nute brand's 'ecosystems'?). They were topped at the same time. Because I have dropped to one light I now have 9 girls-3 Cream Caramel and 6 Psychosister. They are all smelling good but a little pale.

Next I realised I have very soft water compared to where I grew before so on the last watering I just added 0.5ml/lt PM+ Magne-Cal.

-My temps range with a thermometer in the shade at root level is 22°C-28.5°C.

-Lights on 20/4.

-Airflow is 200mm out the window with a reducer to a 250mm outlet and 150mm in from the room running off an SMS Hybrid. Both with oversized carbon filters.

-I have them sat on a 100mm sheet of Celotex too for good measure.

-Also have an oscillating fan and 2 clip-ons churning the air in the tent.
-Bulb is about 2 feet/40cm away but I should measure it to be sure.

A couple of pics that hopefully show what I mean...

The Final 9

Psychosister Cream Caramel 3.5lt

Do I wait and see if the pot up helps them recover or am I missing something obvious?
Heeyeelp!! in my best Penelope Pitstop voice. :scared:

They don't look to bad, the pot up should help.

I would keep it simple just now, environment is okay, getting a little to hot but shouldn't cause any major issues but could be doing with dropping to a couple of degrees to 26C.

I wouldn't add anything just now so ditch the magne-cal.

I would stick to a wet and dry cycle and just water for the next 7-10 days and see where you are after that.

If the yellowing gets worse from the bottom up I would feed a bit of grow, or if you have it Fish Mix, I much prefer Fish Mix in veg :yep:

Cheers ELO. :yep: I have used Fishmix in the past but have Oldtimer Grow this time round. I'll see how they are after 7-10 days of plain water.

I thought the Batmix was a strong compost though so find it hard to believe they wouldn't have enough food in there. Struggling to cool it up there and have thought about getting AC but it would be a pricey installation since no other window is available to extract to.

Na wouldn't get AC costs a lot to run and to buy, 28C is okay, just need have lights off at the hottest point of the day if you can :yep:

Batmix is okay not hot hot but ye should have enough in it which is why I'm saying just water but I would consider Fish Mix if you can get a bottle, really good for the compost and the health of the microherd :yep:

How often do you water and how much? They look over-watered or cold to me, and the compost looks a bit soggy in the 1 pic.. Batmix is strong and too much watering will lead to lockouts and poorly roots.

I was thinking that today too @@uBercaMeL and have hesitated watering a couple of plants that have pulled away from the side of the pots but weigh like they still have a damp core. Not cold though-lowest temps lights off 22°C.

I'll let them all properly dry out this week beyond what I thought was a light-feeling pot-I hope that's the simple answer. :yep:

Yeh. It's strong stuff is the bat. You shouldn't needo to feed them yet.

Did you use bat from the start?

I start them in weak plant magic soil for a couple of weeks before introducing the bat...

That's what I thought Hazy that the Batmix would see them into flower. I started them straight off in to PM+ Soil Supreme then potted on to Bat but may have burnt em a little on this first transplant...
