Ph problem ,, right? +rep for help

I m just making this thread just to be sure that this is a ph problem.. i m 90% sure because until now i was watering my plant with tap water, the first one is GHS the church and the other one is somekind of greek sativa , harvested and rejuvenated. on this one u could see some white marks on the leaf... any help would be nice.. thanks in advance.

Kinda looks like the starting of a magnesium defiency to me, a ph problem would show more yellowing of the leaves. But you need to check the run off of the soil to find out if its a true ph problem. Just my opinion.......

i dont think it's magnesium.. it's too early for such problems , plus i have some epsom salts in my soil mix.. atm i m watering with 6.0ph rain water , i guess that they would be alright.. any other ideas?

They look ok too me. Those little white streaks are probaly nothing to worry about. The first two pics kinda looks a bit of nute stress, thats about all I see.

Well i m kinda relieved tbh. i m gonna stop feeding em for like 2 weeks and then switch to 12/12 and start high PK food..

I would be sure to give them a bit of veg nutes a few days before turning to 12/12. Then start adding your bloom nutes after about the first week of 12/12. The nute stress looks pretty minor. Probaly just a couple of waterings then you can ease back into your nutes. I wouldnt starve them right before changing. They do alot of business those first few weeks of flower.

Well on the church i m gonna follow tight feeding schedule, as u said on the first weeks of flowering, on my last grow i went from veg nuts to bloom nuts but slowly changing from 4/4 veg nuts to 3/4 veg 1/4 bloom and so on so i could swap to 4/4 bloom in 4 weeks, it was effective on my last grow.. i m kinda concerned tho since this one is growing slower than everything i ve grown before.. On the other hand i m really confused with the other plant.. This is my first plant ever rejuvenated and i m going to try some varius feeding schedules.

Thats a very good plan. The slow change from veg to flower is pretty much the basic schedule I use also. I wish you a prosperous grow.

Thanks a lot dude.. good luck on your grows too
