Looks like a Calcium def. to me.
I wouldn’t worry about ph in soil.
Well, just make Sure it’s not to low in the feeding water. With all the nuts you mix in your water Ph will go quite low and the soil can only lower the ph, but not raise it.
GMSgrowsanswered grow question 4 years ago
Your ph is to high for one thing. Needs to be 6.5, 6.8 for flower in soil. You have some ph lockout. You better check it all, check your runoff ph and ec levels. Get them down to proper levels before your things get to bad. Cheers

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

Wet shiny spots on leaves.I find occasionally such wet shiny spots on leaves. Any idea what the root cause and how to fix it?
They are not sticky although look like.
I cannot say whether they smell because smell of the leaf is too strong 😶
I can rub them off with the thumb with no sign

Possible N ToxicityI believe I have a N toxicity issue on my hands. Leaves are a dark evergreen color, and I'm noticing some leaves are curling left or right. I've experienced the full out clawing action a while back but never like this. Is anyone able to confirm? How do they look overall?Thank U!

Brown Spots on LeafsThanks guys, must be the break as it flowered early too... I also noticed some brown spots on both plants, some leafs . Worried it's mold but it wipes off with moisture and I've been misting with molasses water. Staining from too much molasses in the mister maybe?

Sagging leavesI have (2) 9 day old purple punch auto seedlings. They both have sagging leaves and were fine yesterday when I watered them. I think it’s because I have them in 2” peat pots inside solo cups. They get plenty of natural sun. They weren’t watered for 3 days before that.

Bugs creating holes in leafs?Does anyone know what this could be from and the best course of action? I can't find any visible bugs on topside or underside of the leafs. Have been putting her outside for a few hours each day for the last week. Nute burn is from hot soil from bottom of the pot she grew into..
