thi sis very disappointing - not sure what did these plants in
my guess it was the transplant, probably the soil - or something in the soil
you mentioned wood ash, which can be good, but can burn easily if used too freely - a little goes a long ways
but it tough to tell for sure, did the leaves curl and brown? if so, that often means too much nutrient of some kind

that's kind of true, good source of trace minerals
mostly, wood ash is potassium carbonate, and is a very concentrated source of potassium
and it will raise PH sharply, if you use enough - it's all about how much used
i've used it from time to time, dissolve 1 tbsp in 1/2 gallon of water - which raised my water's PH from 6.2 to 6.5 or so
ouch i put about 1 part to 10 parts in my soil
the plant we love has its mysteries, some plants very touchy, others not so much
1 part in 10 sounds 'hot', but i don't know what proportion of soil/ash is recommended
and it could have been a other factors at work, working out your soil mix is a fine art
many have this experience with soil, doing it from the basic ingredients gives you the power to make all kind of growing mediums
it is a harder way to get started with growing, but i bet your 2nd batch of soil will be better than your first

well it all looks good now the second plant looks better ( good enough to save the top bud but it will be flowering much longer than expected i bet) the other one is doing great the buds have really picked up and i guess its the home stretch, i had a lil mite problem but some neem extract daily and home made organic insecticide ( pepper, onions, garlic, organic soap) did the trick i see no more eggs and no brown specs on the new leaves, ( the buds are of the larger plant and the other pic is the other surviving plant ( looks small but its actually close to 3ft)

i've heard that too, they are relentless little devils
the most convincing treatment i've heard is dunking, plant is flipped(with soil held in somehow), then immersed completely in a pail of the insecticide for about a minute or so
haven't tried it, and there seems potential for disaster(dropped plant etc.), but sounds like an effective treatment

I grow sativa under CFLs, the trick is to use small pots, lots of LST, and recently I've had success with topping to keep them short and growing in an "X" pattern. It's working well so far, if you have any more specific questions PM me.

*Also, for the mites try imidacloprid granules, the pesticide enters the plant and kills any bugs feeding for up to like three months. It's reported to be food-safe too.

LOlz i don't have access to name brand insecticides here ( un less in big quantities) , as for the sats under cfl ( how long do you usually veg them. am starting a new grow and i wan every thing to go perfect al lst and maybe find an optimal pot size maybe about 1.5 -2 gal

The last one I vegged about eight weeks, but it took longer because the topping halted growth for a week. The first time I grew Sativa I used 1-gallon size pots, but I had more germinate than I expected so I had one that was left in the 1/2 gallon starter pot and it grew to be the same size as the others, so this last grow I left them in the starter containers (cut off milk jugs) and so far it looks like I'm going to have at least as large a yield. Also this time, I used a 50/50 mix of 2700k and 6500k cfl's for the whole grow (last time I changed from 6500k's to 2700k's when I went to 12/12) and my plants look better this time. My grow box is really short so I've got to do anything I can to keep my plants from hitting the lights, and doing it this way I've been able to keep my plants from getting more than 12 inches above the rim of the pots. If they were stretched out they'd probably be close to 3 feet, but that length is kept horizontal rather than vertical. Oh, and I've found for LST twine and clothespins work really well. I tie the the branch loosely with a surgeons knot (an overhand knot with an extra go round) and then pull it down towards the edge of the pot and clip it (the string) in place with the clothespin. This way you can adjust the strings without undoing anything.
Good luck - Dr.Nick
