Can't determine plant abuse/splotches

[emariek]

I just switched my lighting cycle yesterday and I have noticed that one of my plants has these white splotches on it. It doesn't look like heat damage, and I have plants that are even closer to the light than this one. Maybe over watering? I am also using soil so I do not see how it could be nutrient burn. All of the other ones are fine except this. Can anyone diagnose?

Thanks,

It's not nutrient burn but just because your using soil doesn't mean you can't burn your plants brother...Whats the ph of your soil maybe it's off causing lockout it's not overwatering or underwatering, try this Cannabis Plant and Pest Problem Solver - Pictorial

Sorry I can't help more I'm not a soil grower but I'm sure someone will be along shortly to give you their .02

Try more like sister, but thanks for your input. I tested the pH and everything seems to be fine. I think I am over watering since I've read that they like to dry out in the soil a little bit before they are watered again and Ive been keeping it constantly moist. So far they have still been wet and I haven't watered them, and the spots arent getting any worse so I will see what's up when I water them again.

I would suggest you get a ph & ppm meter and find out what the day old tab water reads. I try to be in the 6.2 ph during veg and 5.8 during flower. that is watering days without nutrients or after nutrients are added I ph up to my target.....the MG soil has nutrients so after you run water thru catch the run off and take a ph reading of the used water. I used MG on my first grow (I switched to bcuzz coco) and would normally get a 5.9-6-1 reading on my run off during flowing.

Also I have learned I always over react the second our lovely ladies show any signs of growing UGLY...Keep a close eye and get a plan in case it progresses. I am curious what the next 2-3 days bring. Good luck.

Over watering cause droopy plants just like underwatering those spots are some kind of defiencey or lockout due to ph or something else

I missed this post as I was typing..You are watering to much..the soil should get dry, dry on top and dry in the middle and slightly moist at the very bottom. Try to remember what you containers weight was prior to watering...I have 5 mother plants and after 30 days you learn to water by feeling the weight of the pot..at least in a smaller container like I use. It might be a different story if was 5 gal bucket. At first i went till I first noticed the fan leaves to start and droop. but after 5 or six waters I could see/feel the weight prior to them getting too dry..Some say waiting till they droop causes unnecessary stress and increase "Hermy Time"

never heard of that...i would imagine it wouldn't really effect them that much to hermy unless its like a swamp 24/7 considering in nature they have droughts and too much rain and its never caused any of mine to hermy

It is what I read....that letting them droop every time to determine they need water can cause stress from not watering...
