Feminized Lowryder Looking Poop!

Hi Chaps and Chapettes,

Im having a bit of a nightmare with some of my feminized lowryders

I grew a batch of lowryders with virtually the same setup approximately 12 months ago with great success: Good yeild(with what you would expect from lowryder) healthy looking little blighters.

However im really unsure of whats going on with this new batch... They are being grown in a compost for all plants with a mix of perlite going in. They are under one of those eco flowering lights, and i have been giving the 24hour light as they flourished last time. I have also been giving them PH balenced water. Temp in grow room is approx 70F. I have layed back on the watering because i was worried that i may be overwatwering from the excitement of growing again, so i have cut back for about 2-3 days but soil still feels slightly damp a few inches down.

They are looking terrible. New growth looks fine for 3-4 days then the delightful appearence of pesky yellow/brown burns. And I arrived home today and the ends of some of the leaves are really really soft and flopping about the place. They are really not in a good place.....

I have attached some pics to see if any of you could come up with some ideas to save this grow. As i cant seem to dignose one thing, as i look down the lists of difficencies it looks like them all.

Please any advise would be welcome.... (other than the obvious buy a proper decent seed rather than lowryder or buy a better setup as thesenk are uneconomically viable....come on there is a credit crunch!)

Thanks

well i do know that 20/4 will give better results that 24/0 for autos. the browning is tell tell nute burn. brown edges etc. I'd say give em a real good flush and dont water until the soil is DRY as hell.. then start with 1/4 strength of the nutes you were giving.maybe the compost is too "hot" for them this time? if it is from the same pile then maybe it could be hotter or jsut nit ready for using? not sure about that, but it looks like nute burn.

Yup, I am going to say maybe nute burn as well. Whatever it is, it's probably something to do with the soil you are using, change it!! Also, have you ever heard of nematodes? I had a pot with 6 hawaiian baby woodrose that started looking horrible and when I investigated the rootsm they had these little worms all over them. The plants ended up dying too, which sucked because they went from being very healthy too dead in a couple months. I won't use a compost anymore at all because they were in some kind of compost as well.

nute burn no doubt

You are crisping them up, flush with at least 4 times the volume as your pots, let them dry out and start at 1/8th the nutes and slowly work your way up to 1/2. Nute only every other or every third watering, unless you notice a def forming. Those leaves will not heal, but your new growth should come in fine opnce you get everything dialed in...
