Hello Guys,
Nick Thanks for strating this thread, Ive learned that I have a Ca def during flowers but it doesnt kill me, here are some pics of what kills me, I grow yor some years now in coco with perlite, seen lots of stuff but never this, it-s driving me crazy I first thought it was Phytophthora Infestans but I read it doesn-t affect marihuana plant, I live in the potato country in South America where that disease is common in potatoes but naaaaaah, can it be a deficiency? I challenge all ya to diagnose this case

Ive looked through different forums, diagrams and books and I still cannot fully Identify what this is? maybe Ca deficiency? Im (DWC) using RO water, DM gold grow parts A&B thats it. PH(5.6-6.3) and ppm (300-450)are looking fine as does the temperature (71). If anyone knows what this could be I would really appreciate input! its only on these two fan leaves that I can tell..

I had some plants start off like that, adjusted the nuits. Turned out worse, I later discovered it was the start of powdery mildew. Hope that's not your problem. Best of luck

i am having the same problem, only on 3 of the 4 large fan leaves, no yellowing yet.too.jpgunder.jpg you can see from underneath that the leaves are actually burning, the ladies are about 18 inches from the light. I watered with nutrients about 2 days ago and it was a light feeding. ph in the soil is around 6.3-6.5

I'm in a top-fed DWC system and a month into the veg. Using CFLs and GH flora trip for nutes and pHed at 5.9. I'm thinking it could be lack of N and mag? Does anyone else think the same or is it nute burn. I transplanted from coco a week I from sprout so I stressed it out and turned the older leave tips yellow and was scared to put full strength nutes in the water but now I'm kinda thinking it might be not enough nutes.
