Canna flush
Thank you so much for the information. I have been using Plagron nutrients for a long time and have never had any major problems. OG is my first to be very sensitive. She went to sleep in the vegetation. It's not working now. Can I do a flush with Canna flush? How I use this? Thx

If my ppm intake is about the same as my ppm runoff but my pH runoff is way lower than intake should I be worried? Or what should I do?
If my ppm intake(705) is right about the same as my ppm runoff(790) but my pH intake(6.7) is off from my pH runoff(5.9) should I be worried or be trying to correct something or should it be fine? Humboldts Secret nutes, Glueberry Og Auto, rh48 temp74-76, advice appreciated.

Ph value is decreasing despite BioBizzUp
I don´t get it I´m trying to increase the Ph value but it is permanently falling again to a value of 4,2. Any idea what could be the reason why my Ph adjustments (BioUp) are not taking effect in the soil. Additional question for SD: What to do with the brown leafes? Remove them?

Possible overfeeding nutes?
Could someone possibly identify the issue on that one leaf? I had another like that a bit worse that where the edges started to curl. They were fan leaves so I ended up removing them as they were a bit worse off. Doing much better now, only guess is too much nutes.

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliage
At first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

Leaf Spots, weak color, and leaf ripple
Please help me identify possible causes of this: small spots on leaves, minor color fade (not burn) along edges, and strange 'ripple' effect. A user commented that he thought my plants looked deficient but hasn't elaborated further yet. What might this be? Multiple issues?

Nutrient Help possibly needed
For 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? Thanks

Not sure why but she is showing either magnesium, calcium, or potassium deficiency. Do you agree? My PH is 6.3 this water, and was 6 the last sprinkle I gave her.

Nutrient Correction?
04/21 - Noticing some possible nutrient issues with the Fruity Pebbles for several days now. She has much more of a pale green color than the others. I’m thinking maybe just a super small amount of Amino Acids with a little Epsom Salt? Maybe fulvic acid and some calcium?
