My bottom leaves are turning yellow - Is this heat/light burn? Or maybe a nitrogen deficiency?

If you're not ph your water you will run into lockout problems. It looks like lack of nitrogen but could be incorrect ph range issuse or over watering issue. 👍🌱

Losing vigor and yellowing
Sorry I don’t have a diary for this grow. I did collect some runoff on one of my girls so hopefully this can help for giving assistance. This is only my 3rd grow and the first 2 went very well but this one isn’t, all plants have lost vigor, are growing slowly and are yellowing.

Good afternoon My first grow on coconut substrate. The edges of the leaves have turned yellow. I give Kalmag at each watering 0.5 ml/l, maybe it’s not enough? Fertilizers Grow 0.9 ml/l Micro 0.6 ml/l Bloom 0.3 ml/l. Ph - 6.0 - 6.2. I noticed problems on the 17th day.

nitrogen deficiency
Hi guys, my plant has a nitrogen deficiency, but I dont know how to fix it. The ph value is correct and I already gave her a lot of CalMag, but things doesnt get better. She already lost 4 leaves and the plant in general looks a lot brighter.

Yellowing of leaves Week 9
Help! Is it normal to have such yellowing Week 9? The buds are still green, but the bigger older leaves are quite yellow. Same strain different plant still very very green. Might be the difference between topping an auto and not topping an auto?

Cal-Mag and N Deficiency in Flower? Thanks!
I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer

Wondering if the amount/type of yellowing leaves is normal at this stage? Seems like maybe a nutrient defeciency (maybe burn? I dunno!) but given the stage of flowering not sure what should/can be done at this point. Have been providing ~1/2 dose bloom nutes (9-16-16). Thanks!

Tips turning into yellow
We started feeding the plants 10 days ago. Some leave tips started to turn yellow, we think is due nutrient burn. We decided to water them without ferts for once, to flush out the excess nutrients. Is it a good approach? Could it be from light stress? (See pic for reference)
