Fixed my mystery issue!

Ever since my last grow whenever I start flowering around week five my leaves always started to turn yellow, and I always thought it was because I was adding a new nutrient that I’m supposed to add such as nitrogen and stuff like that. Come to find out it wasn’t a deficiency at all. The problem was completely fixable. The pH was really low down in the five range so they got watered for a couple weeks like that until I realized it I fixed it my last water this is going to be the second water since I fixed the problem and already everything’s looking better! The plant that isn’t so frosty around the buds is my sativa plant but the one that’s really frosty is my Indica plant. Let me know what y’all think….this is my 4th grow.

So you ph upped some water? What was the fix ?

You know how to train and encourage tops. Can't wait to see the next grow. Nice canopy

Watering at a proper pH or slightly higher since the pH of the soil is buffered low

I always have the same problem, things just get yellower and paler. I might try a drop of ph Up. Is there a harm to water ping a little higher pH in soil? I have purple stems, phosphorus low? Well at low pH it becomes unavailable. Maybe I have lots of mutes I’m just locked out. Ya I’m going to add pH up and watch it explode.

Plants turned green again!

Thank you! I appreciate that!

Yea I jumped it up to seven, checked the runoff cuz I kinda flushed it with high ph and it was 6.5.

Don’t go higher than 7. Try to keep between 6-7. But get the kit on Amazon. I posted a pic in the thread

I’d like to have a legit professional grow one day!

Do a slurry test if you need to evaluate soil pH to determine pH of watering solution

If you don't have runoff, you will need to compensate rootzone pH with input pH. My last run I did no runoff in 5 gal pots of coco and let them just drink up their runoff, the run went fantastic honestly but I did have to start feeding 5.2-5.4 pH towards the end due to upwards pH swing in the rootzone. Also you will need to adjust EC accordingly as well. If you bomb them full strength and aren't giving runoff you can have certain things become toxic.

This is why feeding with runoff is easier, you just allow 10-15% runoff each day and you should have a rootzone pH very close to whatever your input pH was.
