RaS_Audiostarted grow question 4 years ago
I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad

Hey Mate,
Just want to add,
may you wanna have a look at this:
https://www.agrobest.com.au/news/How-Soil-pH-affects-availability-of-plant-nutrients-7.htm
Helped a lot.
You know that your soil can easily puffer the pH of 5.2 for a short periid of time.
I would adjust water pH through the whole flower on 6, and I would stop checking your run off when growing on soil. I think would just consternate.
Good luck and happy trails for the rest of the way 🤞

Seem to be doing a dance between nute burn and lockout as the ph swings in the soil. I think I may just have to flush again. using more water over more time idk.

They are still in veg and the reason the soil is so low ph is I amended it with high P bat guano. Apparently it has a ph as low as 2 and my first flush did not remove enough of it from the soil.

Not only do you need to retain a good pH for your soil, you should also be feeding phosphorus rich nutes while in flower. Make sure you're feeding your plant enough!

Unhappy seedlingSee the photo of one of my seedlings that appears quite unhappy. My guess is light/heat stress, BUT I have 8 other seedlings growing right next to it, under the same grow light, in the same soil, that are doing just fine. See 2nd photo of another of the same strain that's fine.

Upward curling leavesYesterday applied heating mat bcs temp was dropping to 14C nights. Now it stays 30C allday with RH 30%. I have found my seedlings looking like this morning. Leaves look dry. Could this be the excessive heat shock? Or soil dried up quick? What should I do? Water? Raise RH? How?

Brown spots on leavesWhat seems to be the problem with my plant? The old leaves get brown spots whereas the newer ones have yellow edges. Is it a pH issue?
Is there a fix to this?
I grow in soil and the plant is 4-5 weeks old.
Thanks for help!

Deficiency/toxicity?Hi, back again 😂 so the canooing has stopped on some plants but still present in some. I've also noticed the leaves to look a little off, is this the start of something I need to fix? They look pretty healthy other than that. The photos are of different plants. Thanks in advance
