White Cheese 10 days in

[Supacabana]

Right, so everything was going smoothly until I checked on my plants today and the White Cheese is showing some weird coloring on it's 1st set of leaves and the top leaves are pointing straight up. Not sure if it's lockout or deficiency. They're under a 150w HPS and it's a little less than a foot away from the tops.

Soil: Biobizz Light Mix
Ph: 6.9
Temp: 26 deg C (78,8 F)

:smokebuds:Your PH might be a little high,I would go to 6.4 or 6.5. Make sure your light isn't to close causing heat stress.Also make sure your not over watering.Are you feeding them? They shouldn't need nutes yet at this early age.

second what NV said, PH problem would cause yellowness, but as i can see there not much of yellowness in the leaves yet, so it might be overwatering, as you said your heat is fine so i can say its not heat, yet they dont need feeding now feeding will just result in salt build up in soil which will eventually block the roots intake of nuts, ph level has to be 6.4 and more but not up to 6.8, you see, anything less or more than this PH level will result in root block intake of nuts too, other than that the lady might just be structured that way, dont rush things up, wait 3 or 4 more days and update us, see if any more signs show up at that time we can verify exactly what the problem is

good luck growing brutha

Thanks for the quick replies. They get watered twice a week at the moment, and haven't been given any nutes. Will try bring the ph down with the next watering on Monday (watered them yesterday).

I don't feel like shelling out 13€ on a ph down solution, are there any home made ways to get it down i.e. Lemon juice etc?

white vinegar - go real easy! start at 1/4 tsp per gallon!
wait 30 min after mixing well for an accurate reading.

Ok so it's been a couple days, and things seem to have gotten better. Have had some noticeable growth and the yellow blotching seems to have slowed/stopped over the weekend.
I watered them yesterday with pH buffered water of 6.5 and everything seems ok, some pics below...
