Optimal pH for Vermic/Peat/Casting mix?
Overgrothostarted grow question 6y 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?

MangoDuduanswered grow question 6y 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

Can this delay flowering of an auto?What deficiency is this please?
I suspect phosphorus deficiency and as such have reduced the PH from 6.4 back down to 5.8
It is not spreading and appeared spontaniously and at once a few days ago.
Growth has been slow for almost 2 weeks and flowering has refused to initiate.

Leaves yellowingThese leaves are stressing me out. I’m not sure if I’m having a lockout or if I’m not feeding enough phosphorous. Either way, I’ve been using 3 ml/gal of tiger bloom, 3 ml/gal formulex, 3 ml/gal big bud & 1tbsp of molasses for feeding. What do I do ?

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?

Calcium, lock out?Hello, it looks like calcium, P, or K issues. Maybe pH lock out. I flushed last week and followed with nutes. Likely last nutes this week followed by a week or two of flushing before harvest. Please look at leaves and let me know what I should do as I end off this plant.

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).
