Hi I have looked at the diary I think these pics are from. You are using a 3 part nutrient feed with boosters, lucas formula only uses micro and bloom. If your tripart nutes are the same ratios as GH or whatever its called now then you have had the amounts wrong and not had enough nitrogen during veg. Have a look at your manufacturer recomended doses they should vary from veg to flower.

Looks like nitrogen def. Increase the micro a bit as it has the most nitrogen in the 2 bottles your using. Another thing it could be but does not look like it as it's hard to see how dense your canopy is. But if leaves don't receive enough light the plant will drain it from nutrients to focus on leaves getting light.

I use to have this problem when flowering started and it would affect the rest of the grow imo. Not to long ago I learned to give them more cal/mag at the start of flower then taper back to normal after a week or 2

Looks like nitrogen deficiency to me.
Others have said, that the plants get hungrier in bloom phase..
And isn't Lucas formula a feeding schedule for hydroponics?

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.

Day 20 Flower. Leaves curlingLeaves curled over 12 hour light cycle. Ph 6.0. Ppm 950.
I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this.
I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?
