View attachment 1291452 Image 1 : Leaf tips drooped down and discoloration on leaves

image 2.jpgImage 2 : Similar problem again I think

image 4.jpgimage 3.jpgImages 3 & 4 : Strange yellowy lines/blotches on all the leaves on the whole plant.


image 6.jpgimage 5.jpgImages 5 & 6 : Blue Mystic plant that i cut the top off as the buds weren't looking too healthy. These pics are of the remaining bottom half of the plant which ive left to grow as the buds are quite undeveloped but it hasnt changed much at all in the past 2 weeks so just wandering if anyone can tell me how to make the buds thicken up if i leave it to grow longer or will they just stay undense and leafy cause if so i may as well just chop it now!

_____________________________________________________________

The top pics r of my new babies, they were looking really healthy up until about a week ago and now im getting worried about them but I have no idea what to do to save them since i have no idea whats actually wrong with them!!! Any feedback would be REALLY appreciated but please only respond if you really know what you're talking about as getting 10 or so completely different responses from different people will just confuse me more!

Thanks heaps :-P

you should flush really good before adding anything flush her good and go from there if its doesnt get better try adding some cal/mag and maybe some zinc.

Definately flush, it looks to me to be a major salt buildup possibly causing lockout and dehydrating the leaves. If I'm correct in assuming, the air is probably too dry and hot compounding the problem. Pests love to hit plants that look like that so make sure you're watching out for spider mites and if you can, I would do a foliar spray treatment on them.

To take care of the salt buildup, flush a ton. At LEAST 3-5 times the containers volume in water.

Flush the plants really, really well, and make sure you raise your lights. At about 15 minutes before lights out, turn off your fans and try and find a foliar sprayer that makes a fine mist to spray the entire room to increase your humidity to around 50% and add some form of a wetting agent to it to help the water penetrate the dry leaves. I would try and add a few drops of Dawn and that should help it. After an hour or just sometime before your lights come back on, make sure to turn your fans back on.

Watch your temps and humidity over the next week and keep spraying just before lights out IF your humidity is low. Don't go overboard and end up with bud mold or anything like that.

If you have any questions or other concerns, I'll sub to this

Fantastic ill get right on it... we've had a couple of weeks of 90+ degrees here so Im sure ur right about the heat although it has been really humid as well as opposed to dry but I'll still try raising the lights a bit. I just fed them yesterday too with Canna Vega A & B as well as DutchMaster Dr. Repair (high nitrogen) so I've probably made them even worse now but I'll get straight onto that flush.. Do i only need to flush them once and is it too much nutrients that causes the salt build up?

Just lastly too since u clearly know ur stuff, the bud on my blue mystic (images 4 & 5) seems really undeveloped even tho its been flowering for absolutely ages now, is there anything u could recommend to make them become more dense or is there nothing more i can really do? I've been feeding it DutchMaster Flower nutrients and PK 13-14 but nothing seems to be changing on it!

Thanks for taking the time to help me out mate much appreciated ; )

Can i get some more info about your growing conditions and such.

What soil are you using?
What size lighting and is it a cooled reflector or not?
How far from the canopy is your bulb?
Room dimensions?
Room high temp/low temps?
Room high humidity/low humidity?

Unfortunately I can't tell you too much without other than speculating without knowing a little bit more. As to the Blue Mystic, how long do you mean by it's been flowering for ages?

I'm actually looking more and more at your photos and is there anything nearby that might be toxic to the ladies, possibly some kind of gas or residue from a cleaning agent or something. I really think that you likely have some other environmental factor going on and the nutrients may or may not even be involved. If it were me, I would try and move the girls somewhere other than the room and use a solution of hydrogen peroxide (the horticultural ~29% concentration) 1 part to 10 parts water and use a sprayer to sanitize everything. Be careful with the hydrogen peroxide as that shit will burn you.

Make sure to check to make sure you don't have any chemicals nearby. I've heard of people using watertight sealants that were toxic.

Regardless though, whenever you have chlorosis in the leaves like you do, it's best to feed only water. Otherwise, all of those nutrients will just buildup and cause your leaves to heat up internally and dry out.

Get back to me about those room questions and I'll see if I can help but without actually being there, it ends up being a lot of speculation. If you take more pictures, include pictures of the newest growth as well as the damaged leaves.

Good luck to you.
