    Curling leaves - young plant?

    The thing is buds, it had greyness and curling prior when I had them under the 3 CFLs... Surely it would be okay? It doesn't seem to be crisping up but more of a grey colour? Almost like nute burn but I haven't even nuted yet?

    Grey leaves?!

    Also they are under two 400w metal halide lights, previously when growing from couple days old to roughly 2 weeks old, used 3 cfl's at 23 w 23 w and 20w... I previously used the same container for clones before that did not have any succession so perhaps there was some contamination from before...

    Grey leaves?!

    I dont give them nutrients yet as they are meerly seedlings, ph is borderline 6.0, I water every other day.. ppm not too sure about, would it be anything to do with the lights perhaps? Have you seen this before?

    Grey leaves?!

    What can greyness at the tips of the leaves mean? Or grey spots on the leaves? I cannot find much about this is it a disease? :confused:

    Curling leaves - young plant?

    Right, also... There seems to be some grey spots on the first pair of leaves (not the cotyldons) on both plants? The one on the right has it right on the tips and the one on left is hard to see but some small patches.. I've had a look and managed to find nothing about grey spots? What does this...

    Curling leaves - young plant?

    Hi, Need some help determining what the issue is here. Ph is 5.9-6.1, seems the plant on the left has slight yellowing in middle of main leaves, cotlydons are not yellowing much so shouldn't need nutrients yet right? Only using purified water at pH of 6.0 at the moment. No nutrients, under HPS...

    Any recommendations for good A/C units? I live in the UK so I would prefer if I was able to purchase this without the possibilities of importing

    Does this look okay to you?

    Alright guys. Thank you for the assistance. Greatly appreciated! But the thing is, I already have an intake and also an out-take fan... I can't continue to purchase extremely expensive equipment. Upon building the area, Polystyrene was fitting inbetween the walls of the constructed area...

    Does this look okay to you?

    On average, roughly 90-100 degrees unfortunately... That's during the middle of the day, then evens out to 80 rest of the day.

    Thank you so much, will just flush consistantly for a week, should it be PH'd water?

    Does this look okay to you?

    Two of the plants look healthier than ever! But this last one is extra tall and has hit its height limit... For some reason, it has also got dried out leaves all over... If any possible explanation could be given, that would be great! And also a solution too... Roughly 2-3 weeks from harvest...

    Any idea when can harvest?

    (Various pics of three plants. Ak-47, White Widow and Pineapplee Chunk) Just like to know the public's opinion. I reckon another two weeks and all buds will be golden and ready to go! Let me know what you think. Thanks.

    Ill clones and ill plants? HELP - URGENT!

    I use GH nutrient 3 part... But I use 3.4L contrainers instead of 3.8. So my nutes are slightly more concentrated. I have just fed 6.8L of my nute solution which has been slightly weakened. Should I keep watchful eye on my plants and begin flushing if signs are worse? Also, the PH is at 6.0. I...
