I'm 8 weeks on Monday into veg , using perfect 7 soil (perlite ) and ph perfect technology. 4ml per litre of water and feeding around 3 litre water per plant, I never get any fun off however being new to this I'm afraid to over water even though my instinct is to give it more . The small bushy heavy grape is looking fab to me but the other few especially the tall backlava has alot of curling leaves and doesn't look to great . Any help much appreciated. Thanks.
Cause of curling leaves?

What kind of light do you use and have you taken any light measurements at the canopy with the taller plant? It's dropping bad like it's either too dry, getting too much light or you've been over watering. From what you said I don't think you're over watering so I'd lean towards too dry or the lights too strong for the taller of the two.
Mars hydro light, yeah I've took recommended heights from guidelines , putting another scrog net in today as the large one is becoming too big , so plan is to snake it down the middle in-between both lights , I have changed my feeding schedule, I'm now giving a little less but more frequent. I do think it's a case of underwatering ...but not too much and I'd rather that than kill them by drowning them . I'm seeing signs of progression with my new feeding schedule though , might need to start watering every day now as they get bigger ? I have just flipped them to 12/12

I would guess that tallest plant is just too close to the light. Why not top it & bring it down to size with the rest?
Clean up under the net and flip in a week?

Everyone has a preference or style of watering. I like to use really good draining media and water every day to get as much water into them as they need. Over or under watering is the most common issue for newer growers and is something that comes with experience. Lifting the pots to feel the weight after a good soaking to runoff will help you get a feel for when they're dry and feel much lighter to lift. Evening out the canopy as best you can is a great idea. Sounds like you have a good plan for them. Hope you post some nice bud pics here soon.
I did plan on that , however I had the dreaded work men in and it ment I had to take tent down and hide them in a cupboard for 24 hrs ....hopefully scrogging the big one and essentially making it a snake down between both lights will be okay for it , I've been slightly stress training it the past cple weeks
Yeah most definitely, I've heard so many stories on how to water them , my first ever grow so hopefully I'll get better as I go along , I kinda feel like I no already when they are telling me something ...wether good or bad lol ...I'll get it nailed eventually . Just hope my first crop comes down okay , I've got baklava..the big one ...blue sherbert, sorbet and heavy grape . Think if I do it again though I'll only have two of each kind though...different genetics in same tent seems to bring its own issues....

Taking a few leaves to open up the canopy and improve airflow down low is good but go slow. You can't put them back once they're off and that's what powers the plant. Lollipopping the lower buds and leaves after week 3 is a great idea. If it's not going to be getting enough light due to the thickness of the canopy or distance from the light it should be removed to allocate the energy to better areas and it helps cut down on mold and pests.

clawing is caused by over use of "n" also underwatering can cause this - air flow consider cleaing up the inside of the plant. method of growing and experience is the cause of heavy yields
Hi pal,
I have also seen this with cold temperatures, if your using LEDs then I would assume you have cooler temperatures.
IMO plants look like this because:
1) overwatered
2) starting signs of becoming root bound (pot too small)
3) unhappy because too cold.
You already mentioned that it would not be overwatered. Your pots look big enough and the other plant of similar size appears happy with the pot size.
That would lead me to assume they are not happy with the temperature or have experienced recent cold temperatures
occasionally cooler temperatures can lead to the plant not drinking as much which causes overwatering.
Put a temperature gauge next to the root zone and on the same floor as your pot and see what your getting.
Depending on the genetics some plants can tolerate higher or lower temperatures so they may not always react the same despite being in the same environment.
Wish you all the best with fast recovery. Having problems when you are just going into flower can be very stressful
Thanks for the comment , I have once seen the temp dip to around 18 degrees however for the most part I have them around 25-27 degrees ? I really can't seem to pin point it, half the leaves look tremendous and then towards the top of the plant is where they start to drop , I've increased the air flow into the tent , hopefully that will help as been advised that could be the issue, case of trial and error . Thanks again for the advice .
