Hey guys

Let me tell you about my setup first.
I am growing 5 autoflowers (4 Diesel and 1 AK47) in a secret jardin grow tent (90x90x120cm).
I have two KVR super silent fans, one for intake air that is pulling fresh air in from my window and supplying it to the bottoms of my plants. And the other fan is on the outside of my tent pulling air through a rhino pro carbon filter on the inside of the tent, through my cooltube reflector (that has a 400watt MH in it just now for veg), and then exhausted out into my bedroom as clean air (which is also being sucked into a 4ltr tub of ona gel with a fan on top).
I just got 4 ionizing CFL lamps that are 23 watt (similar to 90 watts, producing 1100 lumens each), that are 6000k daytime spectrum, giving a nice amount of blue light. With these new lamps i am going to switch to my 600watt HPS (boosted to 660 watts with my adjusta-watt digi ballast) as soon as i get the hangers for them so that I have both blue and red spectrum in there with the most amount of light possible.
I am also using a temperature and humidity controller for my fans.
And for extra Co2 I am using the Excelofizz Co2 pucks.
My plants are being grown in pro-mix BX soil in 3 gallon airpots (I recentley transplanted them from 5 litre regular pots 3 days ago) and I am feeding them Dutch Pro Nutes.

Ok, so heres how its been going so far. When i started these babys I had them under a non air cooled reflector under a 600 watt HPS and i had my temps way too high (around 40 degrees celsius at the worst of times!), they had been in these conditions for about 3 weeks. To combat this i had to leave my tent open all the time which wasnt really helping for proper air flow inside the tent (and obviously would cause problems when they started to stink). So i got myself a cooltube reflector along with a new adjust-watt ballast that lets me change the power output for diferent lamps, aswell as a 400 watt MH as i think i mighta been stretchin them under the HPS.
I had just been feeding them water everytime the top of my soil was going crusty dry. I did give them a small feeding half way through week two to see if it would help growth, but it didnt and i just got nute burn. I left them to see if they got better and they did, the new leaves came through nice and green and undamaged.

Now, after I transplanted them from the 5 litre regular pots to the 3 gallon airpots I soaked the new soil in alot of water and I think I have overwatered them massively and they started to all droop alot. one of my plants was getting bad yellowing of the newer leaves and the others were very slightly the same (the yellowing started at the join of the leave and the stem and was working its way outwards on the leave) and the stems were getting purple spots on them. I gave the one that was the worst a feed and it started to get greener (i fed them a teaspoon of dutch pro grow soil A+B along with multi total and take root, in half a litre of water). The other ones started to follow so gave them all a feed of the same amounts of nutrients. I dont think they actualy have gotten better and there was one plant that was doing great, it wasnt drooping, it wasnt going pale, and it has started showing lots of white hairs all over the joins, but now its starting to droop alot and is going pale too?

I need someone who has a trained eye to nutrient deficiencies that can tell me which one it is and what i need to feed them to fix the issue (IE: epsom salts or blood and bone?)
Ive got pictures of them all (from the side and a birds eye view) so that you can better tell whats wrong with the girls.

I should point out that i am quite new to growing but i have been doing lots of research into it all and do know quite a bit about how to grow.

Please help fast guys ! :(

Ah, so im just bein paranoid then lol. thats all good then, i did notice somewhere on a forum that your plants will go like this if overwatered, so im kinda relieved now :)

as for your question Keep It Real, I have checked the bottles and all over the internet to find out what nutes are actualy in dutch pro soil nutes, but it doesnt tell me.. anywhere lol. Ive ordered some fox farm nutes to be safe in the future, as ive got no idea what im actualy feeding them just now. They dont even have any N-P-K balance info for them.

yea look fine to me as well, tho maybe a bit over watered and maybe in need for some Ca/Mg
