Droopy Leaves

Could be many things , But make sure your light is not to close to plants check by putting a thermometer to top of plant .should be around 25-29. maybe lack of condition in soil . How are you watering .I find doing the full watering until water comes out the bottom of the pot is hard on plants. Try this 200ml day veg 200ml every second day first 2 weeks of flower 300 ml every second day after that 400ml every second day for last week (flushing) then every 2-4 weeks do a good flush with some good conditioner and chalets (any thing with humid acids) do this by 1 full watering ,when you just see the water coming out of bottom(this will reduce build up) Wait a week or until soil it just about dry 4 on moisture meter and continue daily feeding.They will grow fast and strong
The full watering trick works good in a 5 gal bucket and used if you can't check your plants every day.
Also use a Frolic spray Plants love it(any thing with Frolic acid) I use black gold for frolic and Royal Black for humid and soil conditioner
Ph balance and where you get water is critical too

op2:op2:op2ot size is critical to I use 5" for the first 2weeks from seedling Cutting then go to 3 gal from there on.

yeah it might have been the soil, so i transferred to a different soil a few days ago, and it is doing better. But the leaves are not the correct green, and to two oldest fan leaves are kind of curling at the tips. Any suggestions? thanks for the last post man!

Thinking maybe to heavy on on the nutrients should use only half strength for first 2-3 weeks of recommended nutrients you are using .Could be stress from before too, so give it a couple of days to see if it is reversing. Also check your Ph balance maybe a little high or low 5.5-6 is recommended. What are you using for water ,**chlorine will cause this**. I use distilled water which here has perfect Ph of 5.8 Or rain water is the best.
I know I said it before but over watering will cause this also<- number 1 mistake

well i just watered it with 200mls of water and i guess if i collected rain water it would be better for it? there's no shortage of rain water in Ireland be sure of that! I will keep the changes updated regularly and when i get my camera working again i will do the journal. Its just two leaves that ar giving me trouble the others are doing good now but the color is the only real problem now.

Well rain water PH level would be the closes you will get to being perfect. you should still check the Ph level of it now and then. What kind of nutrients are you feeding it . recheck Ph level ,check nutrients , and check Ph in the soil. you can get Ph meters at local aquarium shop if there is not a good hydro store around. If you did all of that ,then be patient ,it takes way longer to see a correction then is to see a mistake

Oh how many weeks are you into growing I also know of some videos you may want to watch. the first one give you guidelines to feeding for fastest growing technique and the second give you trouble shooting at end of video the second video tells you to water until you see water coming out of pot ,that is the lazy mans way but not the fastest.
