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?

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

Deficiency or screw up?What is this? At first I thought it was a phosphorus deficiency so I flushed with extra bloom nutes & overnight the damage doubled. Is it a pest or did I just fuck up bad? She also has seemed to have stopped growing. No noticeable diff in size recently

Color en las hojasAt the beginning of week 3 of flowering, the leaves are orange, we stopped fertilizing and the problem continues. It's a 10-liter pot, watered with a liter every 3 days, it's a Critical+ auto from Dinafem. I want to solve it but I don't know how, we're in week 4.

What’s wrong with my plant? Root rot?Growing organically with happy frog mixed with a super soil concentrate. I water them with spring bottle water, ph at 7.7. Recharge every 10 days. Top dress 2-2-2 dry amendments.
Plant looks like it has root rot or potassium deficiency. Please tell me what y’all think
