Necrotic spots
RustyNailstarted grow question 6y 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.

Nutrient lockout? [first grow]My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before.
Is it nutrient lockout? Or just deficient?
Appreciate every feedback!

Sequence in the # of leaves points alterated?I have always seen Cannabis showing a constant patter in the leaves sequence.
After the cotiledona, they have first 1 point only , then 3, then 5, then 7 and so on, with Indica normally up to 7-9 and sativas up to 9+.

Spots of concern on leaves, any advice?Spots on leaves showed up, just a few leaves not all. Seems to be around the nodes where I fim'ed her at week 5. Other strain in the room is not affected. Any thoughts? I use a spout pitcher to feed them, I originally thought it was nute burn. Blue Cookies Fem.

Is this light burn?Is this light burn? If not what is it?
It's under a Phillips 13w household led 2700k bulb, it's not the only affected area but it's the most affected and the closest to the bulb.
I plan to add more but don't want the issue to accelerate.
Thanks in advance!
