It is a nutrients deficiency , yellowing is usually caused by a lack of Nitrogen. Your actual nutrients amount is poor/weak so you should increase the dosage right now and if you wanna stabilized your plants then use some Bio grow to bring some more Nitrogen and stop teh yellowing ( the affected leaves won't recover ) Also why are you cutting the edges of the leaves ? if it's because they are burning or something like that thn stop doing it becase i could be a sign of another problme thay we won't be abble to diagnosis if we can't see it

Hey @shantibaba! Without having more info it will be difficult to find the problem, but lets try anyway. 1. Check if you are overwatering them 2. Check if you are giving reasonable levels of Potasium. Since at the start of the flowering it becames more necesary. These could be the problem of yellowish leaves on the downside. Anyway, they look OK for me.

Hey @shantibaba! You can give them more N. On the first 2-3 weeks of flowering they will be on a stretching period so they will need big quantities of N. You can also check your output water (after watering of each plant) meets your EC. For example, you have 400EC water, then you add enzumes, aptus root and biobizz bloom (lets say it goes around 1000EC). This is your input EC. Afther watering the plants, take some residual water and check the EC. If it's beyond your initial EC you are overfertilizing the plant (wich is not the case right now). But if your output EC is below your initial EC you are underfertilizing them (wich I think is the problem here). Hope I helped you!
