Its all good. Just gets less light than the upper canopy. Also, the plant stops using nitrogen in the lower fan leaves first, its why they start falling of at the bottom later in life

Leaves yellowing and burning mid flower
Air exchange, pH, nutes, and water should be good. Could my 230 watt on 100% be too much for her? Does she need more humidity? What causes crispy leaves?

Nutrient lock out?
Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.

2 Yellowing Fan Leaves
I have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges. It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant. From research, it could be the bump in nutes or water issue. Any ideas?

Can I use magnesium sulfate foliarly?
Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.

Cant find pH section. Leaf edges are burnt. Working on a student budget, had to postpone buying pH meter. Local tabwater is 7,03 - 7,74 according to internet. Ill be adjusting pH starting Thursday. Can I go to 6.0 straight away or should I go down in steps of say 0.2 to adapt

Slightly Brown Crinkly Tips
Dose anyone know what could be causing this browning at the leaf edges? It is a bit dry and crinkly to the touch. This is only on the bottom two fan leaves, and only the very tips. All the newer growth looks fine. Nutrient Burn maybe? Should I be worried, or adjust anything?

Nitrogen toxicity and tip burn
Smallest plant (1st pic) was showing nitrogen toxicity and I just fed distilled water at 6.3ph to try and help. Bigger plants had some tip burn and curling up. Thought this would help them. Any tips on how you would treat this please?

Update on previous deficiency question
Update on previous deficiency question The leaves got worse, its still only a few so not too bad. After doing some research i think it could be a Manganese, magnesium and/or Sulphur shortage. I fed some liquid calmag a day ago. I plan to use epsom salt if there is no change
