Optimal pH for Vermic/Peat/Casting mix?
Overgrotho
started 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?

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

Hydro. If the plant is overfed, can the ec possibly go down when they are given new nutes ?
Usually they eat 0.1 ec when I add nute or with a new tank and ph goes up. Then it stabilizes and ph starts to go down till I refeed since I have a small tank. Right now there maybe a nute block but EC still goes down like they are hungry... Hydro with a small tank is confusing..

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

Add CalMag or Manganese? Still slightly discolored and veiny leaves on week 6
Calcium 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.

Deficiency or Nute Lock?
I was a told a week prior I was feeling too much. So I stopped. I left town for 4 days and came home to the current photos. One looks like nitrogen deficiency, the other looks like calcium deficiency except I've fed 1tsp of tiger bloom, .5tsp of Cal-Mag and big bloom last week.

Rusty Leaves
3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.

Homemade inputs???
What do yall think of my diary? All homemade inputs, I invest literally less than 20 bucks in my inputs in the entire grow. I want to prove to you all that you do not need to drop money on bottled nutes, remember bottles are for babies. Challenge me? Just look at my diary

Continuing calmag deficiency
What I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated
