Few plants - few different leaf problems..

Hi guys I have 3 ladies at the moment each looking healthy but with a few issues on some of the leaves.

I have labelled each pic with the corresponding strain and hopefully you guys will know what is the cause.

The Alaskan Ice has healthy leaves but has weird organism looking thing on them?!


The Kings Kush has a few leaves which have gone dry and crispy?

The Chrystal has a few leaves which have gone a yellowy colour with dry brown spots.

All the problems on the leaves are on the lower leaves and not new growth.

All the plants have just gone into their flowering period on weds and have had 3 sets of nutes so far - 1st - 2ml / 1ltr BioGrow, 2nd - 3ml / 1ltr BioGrow, 3rd - (flowering) 3ml / 1ltr BioGrow 1ml / 1 ltr BioBloom 1ml / 1 ltr TopMax. I don't think they have had too many nutes as i'm not anywhere near full strength when I water them. Humidity was around 65-75% when in veg and now around 45-55% during flower. temps have been around 75'F and they have always had constant fresh air and a humidifier in with them.

Any help would be greatly appreciated.

Looks to me like overwatering and incorrect PH. PH is probably the most overlooked thing but is the easiest to have correct. Your ph must be 6.2-6.9 before going into the soil otherwise it will cause nutrient lockout, and all other sorts of deficiencies since the plant cannot uptake ANY nutrients.

As far as watering goes, make sure before you water, that you can pick up the pot and it feels super light, like there is no water in there. You will be able to sell, it will feel almost weightless.

Cheers dude, I always check the pot for its weight before watering, even feeling light I leave it a day so it works hard to find the water then feed them. I have a PH water tester and before I add nutes to the water it is around 6.2-6.4 which I thought was correct? If I start with 6.2-6.4 + add nutes and it is still over how do I reduce the PH level without reducing the potency of the nutes?

Just took a reading and out of the tap was 6.5-6.6, I have found after distilling the water its goes in to the 5.(..) PH ratio which seems too low?

Way too low!!! Adding nutes only further lowers your PH! My tap water is about 7.5 to 8 BEFORE adding nutes, sometimes it gets down to 5.5 after adding nutes and I have to raise it back up into the 6.2-6.9 range. You want it to be about 6.5 with nutes and everything before adding it to the soil. If your water is 6.5 without anything, then you gotta raise that PH. Test out your ph with the nutes and everything added, and let me know what you have. If you need a quick cheap way to raise it, use baking SODA, not powder. Add tiny amounts until the desired PH. Make sure to flush inbetween feedings when using baking soda because using it too often builds up salts.
