Week 6 leaves started to lime from top working down, new growth effected first meaning the nutrient initially causing problem was immobile. P.h has been shifting down most of the time through.the weeks and now sitting at 6.2. At a soil pH of 6.2, aluminum will be present in a relatively low, non-toxic form, as aluminum becomes significantly more soluble and potentially toxic anywhere in the 5's. Soon as you dip into 5's aluminum will start to take over. When pH drops, micronutrients like iron, manganese, zinc, and boron become more soluble and can be absorbed by plants in larger quantities, which can lead to toxicity if the pH is too low. Would move up the lower and the upper range by 0.5 pH units to 6.2 to 6.7—as soils latch on to more nutrients than a soilless substrate such as peat or coir, and risk of nutrient lock-up is lessened along with keeping your base saturation closer to 7. The younger leaves may be more chlorotic than the older leaves due to the sulphur being immobile in the plant. Sulfur also being a macro that is often overlooked but none less essential, be careful tho as it normally acidifys soil further.. Not sure tbh, just trying to help. Looks alot like sulfur to me though. Good luck bfcuk! Hope your team wins at the weekend!.

Hi, I mostly think it's a nutrient deficiency: A lack of nitrogen, potassium, magnesium, or other essential nutrients can cause the leaves to turn yellow. Make sure your plants are getting the right nutrients in sufficient amounts. I would mostly lean towards nitrogen deficiency. But it could also be due to over-fertilization: Too many nutrients can also lead to yellow leaves. The plant can't process excess salts and reacts with discoloration. Another cause could be watering: Both too much and too little water can cause stress and lead to yellow leaves. Make sure the soil is evenly moist but not waterlogged. Or light deficiency: Too little light can impair photosynthesis and cause yellow leaves.
