Cal/mag problem or heat issue?

RudieCantFailstarted grow question 6y ago

A few leaves have some problem spots popping up here in week 6 (see pics). No nutes, PH’d water. FFOF/HF/Perlite mix for medium under 20 hours of light. I’m guessing either got too hot from being in 90F heat for an hour or needs cal/mag? Any advice from any veterans out there?

Hey, buddy! 👋 It looks like the start of a general deficiency; you need to feed your girl like an adult now, she's grown up and wants to eat well. It's the plant's hunger, a lack of necessary nutrients! Increase the dosage of your fertilizers in the watering, bro! 👆 I also recommend watering with a solution at a pH of 6.3 👆 Good luck, friend! ✊😇

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!

I don't think this is nute burn...So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

Leaf issue in Wk 6 Hi I am having a leaf issue late in week 6. It’s been coming on a while. I’m wondering if the ph is out or too high ppm. 7 gal pots in a Scrog, it’s hard to test runoff. I’m starting to flush now so does it matter as much as long as ph is good? More wondering for next run. Thanks

Nutrient deficiency which kind and/or light burn?Do I have some nutrient deficiency or light burn or maybe both? Looks like maybe P or K? I changed my light to a HPS and the plants grew much closer to the light so could be too much PAR/heat so I raised the light. I also had started to add Cal-Mag to my feed just before.

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency. However, only the main cola is affected now. So I also suspect light burn. What's your opinion?
