Nutrient burn/not enough nutes or normal?

Verdosstarted grow question 3y ago

Should I be concerned about the dying leaves near the bottom? I first thought it was nutrient burn but I’m now doubting myself!

It's a bit hard to tell from the picture tbh. Typically bottom leaves yellowing and dying is a sign of the plant pulling nutrients from older growth to newer growth. To me, this looks like either early signs of magnesium deficiency or nitrogen deficiency. Magnesium is a mobile nutrient and shows in the bottom leaves first.

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? Th Is this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

Ongoing pH issues Watered at 6.5 pH and runoff was at 5.5. I am going to start watering at a higher pH today and continue measuring runoff. Should I stop feeding at this time? I have been feeding 1/2 dosage of Fox farms trio with every watering last 2 weeks. Is there likely soil build up to flush?

White leaf tips and spots? Help :(Im using spring water from a mountain near by,but it is pretty acid (~4.8 ph). Could that be the reason my plants have white tips and a spot on the leaf? Or could it be the height of the light? I will raise the ph to about 5.5-6.2 ,so hope for better results. Thank you :)

Forgot to alter pH Hi I forgot to alter the pH. I already have some issues (I think pH? Check picture). What’s worse, overwatering or too high pH? Do I need to flush ASAP or wait till next watering cycle? The pH of the water I used is 7,7 and I have organic potting soil so is it a big deal or not?

Airy buds or just genetics?How does my bud development seem to you? Trichomes aplenty but I feel the leaf to callyx ratio is pretty poor? Perhaps due to something I've done/not done, or simply a predisposition of its genetics? Trichomes still 90% clear. Likely to fatten up in next few weeks as trichs turn?

Ph too Alcaline! Help to naturally bring it down.Guys my soil PH is at between 7.5-7.8, how do i bring it down? The water is at 7.1 and 7.5. Can i use vinegar to fix this? Should i water abundantly like flushing, with vinegar laced water? With what ph? 6.0? 5.0? Im measuring with liquid phenol red so range might be off a bit.
