Hi all..I don't usually ask for help except NOW! Would appreciate any feedback.

Let me give you the lowdown:

The Overall situation:
1. 4 (all fems) in a slight variation of Somas soil mix (C99, AK99 & SSOG)
2. about 5 weeks veg and just flipped them a week ago
3. bushy, tight internodes (not too tight about an inch and a bit) and looking healthy overall with nice thick stems.
4. soil at around 6.3 to 6.5 (will check again tomorrow with some soil slurrys from all 4)
5. only watering (with ph down: canna organic to 6.0-6.1) and adding some plagron roots along the way as the soil is already charged. The plan was to eventually add some calmag along the way (preventive) and to feed with Guano Kalongs Bloom + Guano tea (or guano kalongs taste extract) when I got a few weeks into flo.
6. I am using mineral water and RO water as my tap water is questionable
7. No problems with temps : 26C ON and about 24C OFF

The Problem:
All 4 of them are experiencing the same thing : please refer to the pics : slight yellowing of newer leaves only, no spots, cracks, burns or deformities that I can notice.

Initial Action:This morning I watered them at ph 6.0 with 2ml of aptus calmag (min 2 - max 5ml/liter dosage) AND 1ml of guano kalong bloom N-K 2.5-6 (min 1 to max 2ml/liter dosage). Was thinking maybe calmag or nitrogen..as I was not sure I decided to go slow and monitor while trying to find some help here.

My pics:
There are only two for now..cam was in the car and was in a rush so had to use a crappy phone cam...will post more defined and quality pics tomorrow (plus an updated soil slurry ph test) These two pics are not much to go on but its a start.

Thanks to all in advance..please excuse the over detailed post.

my plants had the same problem about a week ago and i had given them full strength cal mag since then and they dont have that light green spots on them anymore, i believe its an early on mag def and should correct soon, it probably was caused by your ro water not having anyhigin it.

cal mag plus by botanicare has a good amount of calcium, magnesium, nitrogen and even some iron, its a good suplement to add with your base nutes.

Hi all..the situation is not doomed but not improving. My own evaluation is iron lock-out and maybe other elements due to high pH:

Made soil slurry's of all 4 and ended up with : 7.0, 6.9, 6.8 and 6.9. Please refer to the pics.

1. What do you all think?? and suggest?
2. Should I flush with ph'd water or how can I start lower the ph of my soil??


Thanks in advance to all of you​
