Optimal pH for Vermic/Peat/Casting mix?
Optimal pH for Vermic/Peat/Casting mix?
Overgrotho
started grow question 4 years 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

Nitrogen Toxicity?
Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

Grey leaf tips
Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

Strange discoloration
The plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Autos reacting to All-Mix: Slight nitrogen overload?
Pheno one showed very "leathery", weak, hanging leaves of dark green. Same time the fungus gnats had a run and the population doubled. After second LST also the stronger plant showed those signs on the younger upper leaves. Also curled down a little. Slight nitrogen toxicity?

Yellowing Too Fast Or Natural?
I'm roughly 2-3 weeks into flower. Over the last week, I've noticed more yellow leaves than normal. Majority are bigger, older fan leaves but some are moving up the plants. New growths are a nice green and buds look healthy. Am I under feeding or overreacting?

Leaf issues. Lockout? Need to Flush??
Leaf issues started showing up in 2 of 3 plants, progressing fast. Soil runoff tests have been v. high (2000ppm+) so we're assuming it's a lockout issue. We watered 1 day ago, with 200ppm solution so pots are still very wet. Better to let them dry out a bit or flush right away?

Drainage issue
I'm not quite sure why this cup doesn't absorb its waterings when the other two solo cups are getting Watered every day. All 3 cups have no drainage. They are all grown in the same conditions. My first instinct is lack of drainage, do I need to make some holes, bottom or side?
