Rust spots on leaves, second grow and need some confirmation.
JebusHealsstarted grow question 1mo ago
I'm noticing rust spots on my leaves, which I suspect could be due to nutrient burn or lockout, given the PPM is unusually high for this stage of growth. To tackle this, I'm planning a simple flush with some Cal-Mag, keeping the pH at 6.5. Does this sound like the right approach?

It looks more like an excess, nitrogen perhaps; I don't see anything alarming yet. Excess lime/mag can also create stains, with respect to washing..I would choose to give them a few waterings with only water, adequate pH, and continue with the waterings with fertilizers with lower doses. 🙂

Friends need your help! the leaves turn yellow at the seedling stage!Friends, help me figure it out!
First I will describe my conditions! - Tap water 110 ppm - LED QB288 Rspec 250 Watt light works at half the power! - Advanced Nutrients three-component Fertilizers Micro Grow Bloom
now I'll tell you how it was!
after they have sprouted! they were planted in the system! I made the solution on the recommendation of the fertilizer manufacturer! I added 1 ml/l of each component and it turned out 410 ppm! The second week I changed the solution completely and added 2 ml/l of each component, it turned out 600 ppm
the yellowness on the leaves appeared after the first week! I thought it was a magnesium or iron deficiency! and I changed the solution and added 2 ml / l of fertilizers! I keep the ph of the solution within 5.7-6.0
drip irrigation works constantly!
The temperature in the box is 23-25 C - humidity is 40-60%
Inside, there is a fan on top that turns 360 degrees to blow the plants!

Calmag deficiency or Nutrient lockout caused by Pk excess ?Flo+44. Probably I didn't remove Pk fast enough (left it for more than 19 days, should have left it for 15). So I reduced the nutes from 1.15 to 0.70 now, hoping to avoid the lockout... Thx !

Whats going on?So.. 6th week into it. My leaves have various brown spots and yellowing spots in no particular spot. There is some browning on leaf edges. Also tips are up. I am thinking cal mag and to much heat. But not sure. I lifted light up and so far nothing. Also started adding cal mag .

General feedbackAny feedback would be greatly appreciated, to me the plant looks healthy, however it is a bit small considering it’s age, right? I’m thinking it may be because of the cheap ‘300W’ light I was using at the beginning of the grow. What do you guys think? (Video end of week 6)5y ago

Nutrient Help possibly neededFor my first grow I have kept things fairly simple. I had issues with my soil PH which stopped nutrient uptake but seems to have now resolved that for the most part. Are there any other nutes that are recommended to help bud production or am I ok with what I have now? ThanksWeek 8
