Necrotic spots

RustyNailstarted grow question 4 years ago

The last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!

ph or Calcium excess. In my opinion after looking over your diary it's from Calcium Excess. The lucas method is using Bloom and Micro with no grow in the GH trio. It's not phosphorus deficiency. Feeding hydroponics is about balance so you may have a hard time with all that extra P for veg but it's worth a try.

Sudden Leaf Yellowing – Lighting Issue or Something Else?Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

Looks like light stress I assume with the canoe and curl. Moved light from 100% to 75% Stil at 35in from canopy. Should that do the trick? Also should I have already had it at 75% and moved it to 100% during flower? Or how do you guys do your light power

Big difference in first true leaves' size Big 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).
