This one looks like it didn’t like the level of nutrients you gave the other girls. I would give her just ph’ed water the next time you feed the others and see if she perks up for you.

Canna flush
Thank you so much for the information. I have been using Plagron nutrients for a long time and have never had any major problems. OG is my first to be very sensitive. She went to sleep in the vegetation. It's not working now. Can I do a flush with Canna flush? How I use this? Thx

Nutrient deficiency??
I am struggling to find out what my plants are lacking or what I am overdoing here, can someone please help diagnose what this brown spots are on leaves? My guess was boron deficiency I’m worried if I don’t fix it quick it will kill the crop :(

Organic grow Ph/ppm
На органике это мой первый полноценный опыт. Хотелось бы знать, имеют ли смысл замеры ppm/ЕС субстрата на выходе? И почему за трое суток так. Тремительно вырастает PH?

Deficiency of nitrogen
W.Gelato seems its taking too much nitrogen. Ive already made top dressing with worm castings and compost teas but still hungry. My question is: should i add some small dose of NPK mineral based (i have PLAGRON coco A+b) or it would do more bad than good since im doing organic

Calmag every watering?
Should I be adding calmag+ to every watering? I've been using 50/50 pur+ tap water and distilled water. Ppm is 245 at 50/50 and pur+ filters chlorine. I've also added 1tbsp per gallon of unsulphured molasses and that adds 68ppm. Day 40 right now.

Zinc deficiency?
My plant's top leaves appear thin and pale. My ideas are iron deficiency or zinc deficiency. I'm using RO water. The plant was recently aggressively trimmed of course. Should i flush with non-RO water to increase the zinc?

Yellowish spots ? Magnesium Deficiency ?
I noticed that on some leaves (not the new ones) there were 2-3 yellowish spots. And on a large leave, a point that turns brown. I thought about a small deficiency in Magnesium?

Nutes in flower
Anyone have any feedback on running high ppm in flower with RO water? Does SLF-100 help flush unresolved nutes? My first grow but I think I'm blowing it, please look and tell me what I'm doing wrong.

Calcium in tap water
Is 95mg/L calcium too much in tap water? (It's probably a little lower than that, since that's exit measurement from the waterworks.) I haven't seen any signs of acute calcium toxicity, but I'm worried about buildup.
