what is causing the brown spots on this seedling they keep getting bigger
she has a sister who is fed the same bottle of mix and has no heath issues
could it be the soil is P def or ?
Looks like a nut burn to me.
Since you’re in soil I don’t think it has anything to do with the Ph.
Even though the other one is fine you can’t base your decision on that. Some plants can take more then others.
I usually go the first 2 weeks with plain water, the soil should have plenty of nuts. The Bio-grow is very concentrated.
@Hemporio_Afghani, ph in soil needs to be around 6.3 for plants in veg. 6.5 to 6.8 in flower. When your ph is out it stops proper nitrogen and other trace elements to not be available. If your having trouble getting the ph in the soil down you can get a little aluminum sulphate from a nursery add a little, water through and check your ph after a little bit. Luck my friend.
Looking like your having some slight issues here with watering. As from the pictures I can see that the median is wet indicating to me that you are overwatering these lovely ladies. My advice to you is this, firstly always remember that sickly plants will absorb less then a healthy plant. Secondly I would dial back the amount of water your giving to the affected plants until your median starts to dry up some. Being that your in dirt and have a fabric pot the outter layer of dirt will get dry quickly but the middle will retain like a sponge and over time if you keep watering you will end up with dying leaves and water issues.
Its best to keep in mind that plants need a wet/dry cycle in order to be healthy. Typically this cycle is 3-4 days depending on median sometimes even 2 days. Being that your in dirt it should be taking you anywhere from 3-4 days between watering. You can reduce the amount of time by having a fan blow a breeze at your fabric pots not on top but rather have the air flow around the pot itself or adding perlite to your mix so that the median is composed of 40% perlite and 60% dirt. You can get a vague estimate when its time to water by picking up the pot to feel its weight. In order to have a proper feel water one of your plants till you get 15% run off then pick up the pot it should be super duper heavy, then pick up a pot from a plant that needs water so you can feel the weight difference.
I hope this information serves you well on your grow journey!
Happy Growing!

@The_Projexx,
all very sound advice, usually they aren't as wet as this, 😅
generally they get a light feed from a 5l pressure sprayer to help simulate rain
as that makes using less water per feed easier and also reduces the soil compaction cause by flood feeding
(its also physically less demanding for patients, cant recommend it to people enough 😍)
its this wet due to a fungal gnat issue 😩 that is was treated with nematodes they are applied as a soil drench
the fungal gnats were caused by wet substrate but the sub was wet because their was ph issues and salt build up 😬 so the soil was flushed
the other contributing factor was in order to combat low humidity water was poured on the floor most days 😅
but the pots are fabric so the bottom of the sub was wet all the time and that's how the gnats happened 😑
since the soil was drenched with nematodes a new humidifier was installed and now the subs much dryer and the humidity is much more even now 😁
still genuinely really appreciate the friendly advice 😊 its why GD is so useable its such a friendly community of people sharing information 😇
"growing together" 😁 some other forums have allot of miss info or aren't new user friendly never-mind the unpleasant ethos conventional social media has
<3
@DreamOn,
thank you,
she has had her troubles but is recovering fast hopefully she get big ...
the other girl her age had a rather nasty accident that ended in her getting topped but later than is beneficial
its not really a technique that does well with auto so ....
this gen will be getting a full rerun at some point just so see how they perform without so meany issues 😸
