Switched from HPS to LED and need some help. Lumatek 600W Pro

[Holminator]

Hello.

Started a new grow after a little break but this time with a brand new setup and Lumatek 600W Pro.
I got some clones that were left in rockwool cubes very long and had many roots, they had almost gone into flower.

When i got them i planted into 1L Air Pots and they did not like that. After a couple of weeks of looking very weak they got placed into the pots they are in now (see pics) The nutrients they received were also no good, im used to from HPS to just give 35ml-Canna Vega
25ml-Cannazym and 20ml-Rhizotonic per 10L through the whole veg process, but this time i wanted to follow the feeding chart. Long story short, i shouldnt have done that, i left for vacation shortly after getting them, about two weeks. So i had a friend tend to them while i was away and wrote down feed instructions of 10ml Vega and 40ml Rhizotonic, and that is what they got for a little bit over 1month. All because my high dumbass forgot i changed the formula.
So i changed that a little bit over two weeks ago to about 35ml Vega, 25ml cannazym and 15ml Rhizotonic. They responded well to that, so i had not turned up the lights from 25% either so i turned them up from 25% to 75 in these weeks. I had the lights up to around 30k LUX which with my math was about 30000*0,014=420 PAR. Tent-Temps around 25-26C leaf temp -1C with 50%RH at 75% brightness. Night time 23C 60%RH

In the last few days they have not been too happy, v-shaped leaves and droopy. I have been worried its overwatering but im very unsure. Would appreciate some advice and help from other people.

Someone recommended upping the nutrients, so i just mixed up 50ml Vega 25ml cannazym and 20ml Rhizotonic in 10L water.

Sorry for the long post, just wanted to provide as much detail as possible.
Many dumb mistakes in this grow on my part…
To anyone who read this, thank you.

Also i have not seen the expected growth rate also a reason for upping 35ml Vega to 50ml per 10L. Tell me if im wrong. Need help here.

These pots look very dry. Dusty dry. Try giving each plant 1/2 cup of water every 10 min for an hour. Slowly pour 1/2 cup in each plant 6 times so that the medium has time to soak up the water. Stop feeding for a bit. Let them settle in. Stick your finger deep into each pot every day or so. It will tell you when you need to water again. Don't splash water. Soak them good and let them dry out 3 or 4 days between watering. The light 75% may be a little high. Maybe back it off to 50%. These new LED bulbs burn plants pretty easy. Give them 2 weeks and see how they look.
