2nd grow did great on the 1st one cant figure out whats going on

so i have two big plants and 4 small clones the clones im not worried about but the big ones have been flowering for 5 weeks now started counting when flowers 1st appeared anyway the leaves are sickly looking and every leaf on EVERY plant has whit/yellow tips curling downward. I looked in plant guides cant find anything describing what im seeing its not overwatered, i water about every 5 days and i fertilize evry other watering so its not over fert either preyty sure the soil isn't too acidic it has dolomitic lime, basically Im doing everything i did with my 1st grow and i had no problems at all with that, the buds are small as hell I just don't get it PLZ HELP

Looks like heavy light deficiency. What are you using? Also, is there a possibility of any light leaks during the off hour?

It looks to me you have over nuted. Too much nutrients. In my opinion.

5 days? my soil dried a lot quicker than that,as plants get larger they drink more so you should water more often,once the soil dries too fast the plants will be sucking on dry as nutes with the end result of nute burn,crunchy leaves and the susceptibility to heat stress.Don't water every 5 days water when they need it,how would you like if i fed you every 5 days and you got hungry or thirsty at day 2-3.

Looks like nutes burn. Water when needed not a schedule.

I do water as needed thats kust how long it takes for them to get dry and the soil is still a little moist about 2 inches under the top i use 3 lights a 70 watt mh and hps which i alternate every day a 55 watt cfl equivalent to 200 watts and a 100 watt equiv cfl that runs on 26 watts they are in a closet the closet has been taped on all sides so i dont think any light is getting in there also when i do fert i use half the reccomended strength I think i may do a flush just to be on the safe side though, I just dont see how the could have nute burn would a high alkaline soil cause this?

also the biggest plant which is the mother of the clones she had this leaf problem starting in april but it didnt start looking bad until a few weeks ago and thats when the others got it too I didnt change anything Im at a lost
