Optimal pH for Vermic/Peat/Casting mix?
Overgrothostarted grow question 5y ago
Seeing as I am using 1/3 vermiculite 1/3 peat and 1/3 worm casting for these seedlings, should the optimal pH of the substrate be 6, 6.3, or 6.5?

you want right around 6.3 as this is the happy spot. hope this helps
MangoDuduanswered grow question 5y ago
I think your mix is not well done, so much vermiculite will ever overwater your plants, like u can see they are not full healty and not for ph problem.
however 5.8 soiless is the right range

Are you using soil at all? If it is a soiless mix then 5.5 to 6 ph in veg and 6.0 to 6.5 in flower. Cheers

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliageAt first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

To Nute or Not?About to hit two weeks. Growth has been steady, but slow. In lambert's cactus/succ. mix. I want them to be in a bigger pot and different soil, but they seem too little to transfer atm. Do they look like they're starting to lacking nutes? Did suffer some light/heat :(

Are those nutrient defficiencies? Which ones?A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).

Help with lockout of deficiencies. Don’t know what to do from here I already flushed em but doesn’t seem they uptake anymoreNeut lockout/Deficiency? I was watering less more frequently in fabric pots. I believe it created a lockout in the 3 taller plants by not allowing more run off of water. Correct me if I’m wrong there but what do I do now? They are not looking well and now the leaves are curling
