Indoors or outdoors? Indoors
What strain? Chocolope
How old are the plants? 6 weeks
What type of lights and how many watts? 1 1000W, vertical hung in center
How far from the lights? ~3.5 feet but were at 2.5 feet earlier
What is your watering frequency and source of water? Once every other day so when the pots feel light. Filtered Well water through smallboy, pH downed to 5.8 after nutrients.

What, how much and when was it fed? NPK? Mostly smallboy H20, roots excel, and drip clean. 1 H&G 2 part feed and 1/2 strength cal mag at ~600ppm. One calmag foliar spray yesterday with 300ppm calmag and water.
What is the medium/runoff pH and PPM if in hydro? Unknown, can check at nextwatering.
What are the temps and humidity in the room? 75 degrees, 30% Humidity.
What size pots? 7 gal.
Any bugs? Look real close. No.
Any other pertinent info? Yes, see below. Recently transplanted.



Please help!



I bought these chocolopes in week 5 of Veg. They were in 7gal bags of coco, and I wanted to transplant them into Smart Pots. So, carefully I trimmed the rootball (which I've done successfully before on mothers) to fit the smart pot and repottted them 1 week ago today.



They weren't doing too much for 3 or 4 days due to the transplant, then all of a sudden over the last few days things have gone downhill quick and I'm worried.



I did do a foliar spray of sm90 (1 parts to 5 water) mixed with azamax (low dose) as a preventative spray shortly after the transplant. I also sprayed with tap water the next day to make sure the Stomata was clear. It's worth noting that the azamax and sm90 are 2 years old, but have been stored in cool, dark storage.



Since the transplant I've mostly been watering with water from the small-boy filter, roots excellerateur and drip clean. I did do one feeding before they took a turn for the worse with H&G 2 part base combined with 1/2 strength cal-mag at 650ppm.



To me, the problem looks like a magnesium deficiency. But I don't know how it could get out of hand so quickly, especially when I added 1/2 strength cal-mag to a feed. I did a folair spray of cal-mag yesterday and a light watering with 300ppm, only cal-mag in filtered water. I have only fed them this one time since problems arose to minimize the amount of things that could be contributing to the problem.



pH and PPM have been kept between 5.6-6.0 using a blue lab meter.



Any help would be greatly appreciated! The leaves are becoming so twisted they are curly-cueing. I'm worried and sad

bump?

What you see as a magnesium deficiency is more likely a potassium deficiency, but the real problem here looks like you tore up your roots when you transplanted.

The transplant was a disaster and now your burning it with sprays and shit trying to correct the shock. The cutting of the roots didn't help. Also its a bit warm in there at peak. Stop sprays,watering etc until it shows signs of recovery, Raise the light.
Transplant shock can take up 3 weeks before improvement.

Thanks for the input. What makes you think it is a potassium deficiency instead of magnesium?

Thank you. Do you think the plants will recover back to vigorous growth and be worth flowering? Is there any chance of herming later in flower from stress in veg?

I don't know if it's actually potassium deficiency, but low potassium is related to water stress and causes yellowing along the leaf margins. Mg deficiency is more of a lime green color. Plants need about 4 times as much potassium as they do magnesium, and twice as much calcium as magnesium. Mg deficiency is actually somewhat rare, and is usually caused by lockout or antagonism by too much calcium.

All this is moot point though as I really think the main problem is that you ripped the roots.

Thanks, do you think they'll recover?

i would try and save them by cuttin tops off. this wil put her in emergency repait mode only chance you got. so go down each branch and cut down 1-2 nodes take the clones and try and grow them. this should pu tplant into emergency repair mode.

Really? That sounds a bit harsh, I could see that working but on the other hand part of me thinks I should be as gentle as possible instead...

your killing it with kindness, leave it be for a while. No sprays or anything else. Looks like to much nitrogen, water and care. Stop

no really topping.. its either gonna live or die. did you spray bug bomb or something around it. on it? did the lights get to close? either way the tops are fried. so if it was mine i would top it down to where it can rebuild. it will grow back fast.

in veg it will recover. faster if the fried tops are off.
and slow down on the watering. oh did you mist her leaves under a big light? that would fry her also.
