@BonusPackage Magnesium deficiency You may need to raise the ph up a bit between 6.2-6.5 would be ideal
This will allow all of the nutrients to be absorbed better

1st time grower - nute burn? Lockout? Potassium def? Light burn? HELP PLEASEExperiencing some deficiencies/light burn/heat stress. Says SSH likes hot/moist climate. Plants are planted in FFOF Soil, fed them 15oz of nutes yesterday. Using advanced nutrient systems, see above. Light is a SF1000 LED meant for a 2x2 tent. Would that burn them hanging at 20”?

Saw this first day of 12/12Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.

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?

Cal/mag problem or heat issue?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?

Is this possible nutrient burn?Sour Kush Day 24 (Coco/perlite) - brown tip appearing on lower fan leaves. I suspect it's nutrient burn. Flushed with 900cc PH neutral water, lot of runoff, PPM was 391 (PPM in 495). Should I cut back on feeding by diluting the nutrient water or by watering less frequently? TY

Help! Why are my leaves turning yellow?Not sure why some of her leaves are yellowing on the edges.
Is this due to environment?
- 78.3°F | 64.8%RH
Or a watering issue?
- Currently she's drinking 8-9 cups a day through a sub-irrigated planter (EarthBox).
Or maybe a deficiency?
- See Logs for complete details.![EarthBox [LOS] - Seedsman - Black Sugar](https://bucket.growdiaries.com/static/post/photo/47591/5900471_64bdbe6061a9096a465dbcce72cb872b_m.jpg)

Leaf issue in Wk 6Hi 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

Nute burn (Added nuts to supersoil)So, I added unnecessary nutrients to my super soil and end up with nute burn, I Flushed until ppm was 1100 it was over 6000, and since i've been dealing with yellowing and curling leafs, brown spots and well it's all going down so quick. Any idea how to fix this. I'm lost.

Progressive yellowing on older fan leaves ~F14-F35Hi, past two weeks or so I've been noticing progressive chlorosis and eventually some necrosis starting from the edges of the leaves and working inwards.
Photos of this can be found in Week 18 Flower denoted by "For grow question #x 12/1"
Humidity low, could be related?
