You have a ph in your substrate is off. You are in lock out on several nutritional needs. Run enough of correct ph water through soil till run off reads in range then replenish nutrition.

What’s your opinion on this one?
What you think about it? Is she getting too much? I’m not giving her too much in my opinion. Her stems are purple and the leaves are yellowing a bit. Watering always with ph 6,3-6,5. Thanks for your help! Happy growing!

High TDS and low ph runoff - Lockout? deficiency?
Struggling with some bad soil (beginners mistake). I water with dechlorinated tap water at around ph 7.4 and 400ppm (not feeding yet). But runoff ph is 6 and around 1000 ppm. Am I dealing with a N-lockout? why such a ph difference and high TDS value?

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?
Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

Yellowing leave tips and clawing down, do I need to start giving more nutrients?
Hello all, I'm experiencing some yellowing leave tips on newer growth, it is paired with some light clawing (downside) on the newest leaves (only on the green gelato). I have used very little nutrients so far and have fertigated only once in fear of giving too much.

45 days flowering yellowing
45 days of flowering, is it a bad yellowing or it's normal for this phase? Always did 1ml/L of biogrow, I think I'll put 2ml/L till flush. It's nitrogen, right?

Nute burn or something else?
My middle and top leaves are yellowing from the tip and edge inward, is this the nutrient burn or another issue altogether? Runoff PH was 5.9 and ppm was 700.

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?
