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

Should I remove foliage affected by deficiency, or just let it ride?Autoflower started showing sign of deficiency at week 8. Assuming CalMag, as I filter my water and affected area is new growth at top of plant (see pic).
1) Can someone confirm CalMag deficiency or something else?

Leaf spots issueDoes anyone know what is causing the leaves to look like this?
Throughout the whole grow i've had brown spots as you can see in the older pictures, although adding calmag didn't really fix the issue.
If anyone has an idea of what this could be please let me know!

Add CalMag or Manganese? Still slightly discolored and veiny leaves on week 6Calcium or Manganese deficiency? Last week had what I thought was early calcium deficiency. Gave it a dose of CalMag but now not sure if it’s still Calcium or possibly Manganese.
I do mean manganese but I realize it could be a CalMag or Manganese deficiency as well.

Low PH runoff, dealing with deficiency due to low soil PH. Added lime and PH went from 5.4 to 5.0 after watering. How to raise it safely and quickly?I have been dealing with a nutrient deficiency so added nutrients.It looked ok but then got a bit worse and I took some runoff readings which were 5.4 and then 5.0 the next week after adding lime to raise soil PH. How can I best raise the soil Ph being that I added lime already.

Lockout? Can I remedy this late in the game?I think this is more than a K deficiency. I think I'm getting lockout. And a lot of it. She's an auto-flower, and I grow hydroponically. Can I even remedy it at this point?

Yellowing leave tips and clawing down, do I need to start giving more nutrients?Hello all, I'm experiencing some yellowing leave tips on newer growth, it is paired with some light clawing (downside) on the newest leaves (only on the green gelato). I have used very little nutrients so far and have fertigated only once in fear of giving too much.
