Been growing 5 years still need some advice with new problem

[fartoblue]

As title says been growing for 5 years so not a complete novice. Usually if I have a poor grow I can do some research and work out what went wrong so I don't make the same mistake again but this one has me beat.

Feeding full range of Vitalink nutrients: Coir Max, Buddy - PK, Fulvic, Turbo (Contains L-amino acids and brassinosteroids)
Every other aspect of the grow was perfect, temps (room and feed) humidity. Growing in two separate rooms one lights on daytime the other lights on night time. Both rooms had same problem. I have changed a few thing so trying to find out the problem.

Problem very very poor yield apart from one plant out of 18 which yielded 16 oz dry but seeded. All was fine until two weeks into flower when the leaf stalks seemed to shoot for the sky and the buds just halted. Absolutely healthy plants leaf wise showing no excess or deficiency's but did stretch.
At 9 weeks harvest they looked like they were 3 weeks in. As mentioned the leaves and stalks were all pointing up almost vertical. See photos at 9 weeks just before harvest.


I was feeding recirculating for 15 minutes, 3 times per day in 20 litre pots, medium 60/40 clay coco. Feed tank 100 litres changed weekly

Added an intake fan rather than my normal passive intake (8 inch intake 10 inch exhaust) room size 2.2w x 2.0 h x 3.4 long.

Lights are 3 x HPS

All clones of the same mom taken at the same time? Have you grown this same plant before?

All grown from seed 4 different strains all looked the same... very poor

What's your EC when you change your res water?

 

[coreywebster]

Are you sure they aren't all seeded, have you checked for micro seeds ?

 

[xtsho]

It's all that stuff you're feeding them. Just do base nutrients and skip the additives.

What's your EC when you change your res water?

Around 1.8 ec in full flower.

No just one was seeded

Was thinking of trying Athena dry feed but it costs £400 to buy here in UK. I hear it is a great stand alone feed.

Just use canna or Dutch Pro or any base nutes.

I don't know if it's anything to do with feed tbh, looking through your range it's no different from any other, not like your using ripen or something.

Have you double checked your timers?
Sure your getting that dark period ect?

The only time I've had a crop just stop growing like that is when they've been pollinated.

Only other thing I can suggest is shit genetics

Edit, I tell a lie, I did have similar happen when I once used ripen on a batch that didn't want to finish and then reused the coco which must of had traces in it.
Maybe check the ingredients of your turbo against ghe ripen?

I understand the environment is perfect, but what is temps and RH exactly?

Those leaves look hot up top, all curled up.

What is leaf temp of curled leaves? Notice the ones a few nodes below are flat.

The curled leaves and pointing up is a classic light-avoidance response

I agree. I believe the tacoing is from environmental stress.

I noticed that too, also, new leaves are not showing serrations, which usually means reveg.

How many hours have you used the same bulbs?

Thanks Corey, I did think I may have left a segment in on the timer but hadn't. I'm changing tactics for the next grow no additives apart from PK and will do drain to waste.

Maybe 3 grows from memory.

Man...that sucks. I quickly looked up some UK shops and they love to sell the pricey liquid ferts. Screw Athena, they buy their salts from the same manufacturers, mix them slightly different and then sell them at 4x the price since they market to cannabis growers.

I know in the US if I buy dry ferts from mainstream agricultural distributers like, Growmore, ICL, Masterblend, Haifa, Southern AG, JR.Peters and Yara the price for 25 pounds each of base salt, Calnit and epsom would run me about $150 if I did a little shopping.
Maybe some of those products are in the UK, if not I would look to see who distributes to the professional agricultural market and try to source from them. Like I said, it's all the same shit in a bag....just with different labels.
