This is my first growth, luckily my first 2 were females but as of now one of my plants got hurt pretty bad when I put it ina bigger bucket, and one stayed healthy and grew content, the one which got shocked now is growing healthy and good and the other ones leaves are drying and dieng but new ones are coming out lighter color and healthy still.. My ph is 7.0-7.5 water + soil tested, I have great light not one spot is being missed and temp is about 70 degrees fereignheight. I feel like this shouldn't be happening but it is my first grow.
What I'm looking for : why are my big leaves drying and dieng ?

And they were growing beautifully at first, no yellowing

Edit unless you meant yellowing before they shriveled and died , than yes.

You need to get your ph in check, too high. Soil should fall between 6.3-6.8. I shoot for 6.5, thus no nute lock in my girls. I would get a ph pen from Amazon (cheap) to monitor your water/nute solution going into the soil. This would be a good place to start.
Good luck

Well my ph doesn't really get higher than 7.5 ... And from most forums i read they say that's normal. So lower my PH? But all my other plants are growing healthy here's one that experienced shock during transition to a 5 gallon growing healthy, smelling skunkish but looks good.

Ha thanks. I know it's not the best but I'm just someone wanting to try something new. I'm making a new room for them this is just temporary but it has 1800 watts plus 2 side LEDS and a heat lamp.
I don't think it needs more light. I must've shadowed the light so it looks a bit dark

Not really telling me why my leaves are doing this? Besides get mirrors I have huge light supply on them. All 6 of my babies r coming up fine and one is growing nicely adapting well from its previous almost shock . And the one I posted is starting to restore color but leaves r still dying should I cut them off or allow them to dry and die off ?

1800 w is way too much for that plant, you could get a plant that size with around 100-200W of lighting. I don't see how many you have but i think you may have gone overkill on the lights
my guess is heat stress, your roots should fall around 68 deg F, try getting a soil thermometer and sticking it in there
edit: you don't want it too cold either. If your day temps are 70 what are night temps? The average of these will give you an idea of your soil temp

also be sure not to overwater. This can cause pH issues even if the soil is buffered, and cause deficiencies. Stick your finger in there or lift em up to feel how heavy they are before you water
If you're in soil be sure it's good soil or your gonna have problems

by the way don't use mirrors or foil, goto walmart/kmart into hunting sect and get emergency blankets. Hold them to the light and look through to see which side faces out, and staple it to the walls with a little piece of cardboard to grab more surface and prevent ripping

oh yeah is there a fan in there oscillating ? the main stalks look prettty wispy

It's indoor and pretty much u can say insulated room temp stays the same. And honestly heat stress might be it I took the idea of having a heat lamp from a reptile to give the room a little more heat but it's like beaming heat into one direction I turned that off and I'll see how it re acts but this light was used on one plant before only one and came out beautifully, it was a friends. I did research 1000 watts can do what I'm trying to do but I also heard the more light as long as it's not right on it will be good especially since there's 3 babies coming up healthy and thick, and the other 2 big ones grew about a foot within the past 20-30 days... Idk what stretching or much of anything is that's why I'm trying to figure out what I have to do to get my babies back rolling..

How high is your light hung above the plants? Even with a lot of watts, if the light is too far above them they could still stretch. It looks like a combination of nitrogen deficiency and heat stress, the way the yellowing is closer to the base working its way upward with new growth at the top, combined with the curling and drying out of the upper leaves... Try cooling the room down, make sure your lights arent too far above the canopy, make sure the heat isn't too much (get a surface laser thermometer for like $10)... Set up ventilation to air cool the light if necessary. As far as the potential nitrogen deficiency, try using some PH Down to get as close to that ideal spot as you can (6.1 is like the best ph you can have in most cases but plant strains vary slightly I think). If you cant find any ph down or wait for it to come in the mail, flush the plants with water and let the soil start to dry out before watering again with nutes (use like 3/4 the recommended amount of nutrients).

I'd say about 2-3 ft high

Wow thank you! Will try I just got some ph down from the pet store that'd work right? And I just flushed em and letting them dry lowered my bulb a little bit and u can already tell a little difference
