Yellowing leaves
RootsmanNLstarted grow question 5 months ago
Strawberry Lemonade has yellowing leaves. What should I do to solve it? It is an Organic grow and never measured the ph of my water until now. Ph of my water is 7,7. With the nutrients the ph is 5,7. I alternate between water and nutrition Every 2 days. Runoff water has ph 7,0.

I alternate when i feed. I feed, then 3 days later i water calmag only. I have no issues.
Looks like you are in need of some calmag, though your diary says you are using it. Your pH value of 7.0 is not ideal for nutrient uptake. It's not ideal for calcium uptake either. In fact it's not a good range at all for calcium uptake. You'd be wise to drop it to a 6.2 pH. Calcium is shown to be at the peak availability at a 6.2 pH Magnesium as well. Magnesium is responsible for chloraphyl production so if your plants are turning yellow in flower it could be a solution to just add a little epsom salts. They say calcium take a ride on the back of nitrogen molecules to get to the plant, but in flower nitrogen isn't really used much. It gets confusing sometimes because you are in flower yet it looks like a lack of nitrogen the way they uniformly yellow and the tips curl back and die like that one pic.
I'd suggest you drop that pH to 6.2 on your next feed, and make sure you are giving around 1200ppm in that feed. Things should improve.

Don't alternate between water and nutrition. Fertilisers have to be used every watering.
That's what caused a general deficiency on your plant.

I agree with @Organoman hungry, You don't need any brand name ph up or down an acid is an acid, the elements and compounds do not change, almost everything is using a form of phosphoric acid for down and potassium hydroxide for up. Some are mixes and include citric acid some are more concentrated but in the end it does not matter the brand.
Soil PH is going to manage its self quote well if it is indeed soil. The plants look descent but they also look hungry for some N.
I'd try not to go below 6.2PH with bio buzz nutrients. might need to let em sit out for a day to stabilize the PH. runoff is looking fine.
If you have yet to calibrate your PH pen I suggest doing that as well to confirm they are the accurate results.
Remember to try and get some runoff with feeding liquid nutrients to prevent any buildup that will cause some lock out.
Good Luck!

During the mid/late flowering phase the ideal pH is 6.5 and want to keep the pH as stable as possible. Your tap water is too alkaline and with nutrients too acidic.
Because it is an organic grow my advice is to buy Biobizz Bio pH+ and Biobizz pH-
You can buy them at greensell for euro 8.45 for the plus and euro 9.45 for the minus.
And then just simply adjust the tap water to pH 6.5 with the Ph- and the nutrient solution to pH 6.5 with the pH+

Harvesting a struggling plant or just letting it fightCan she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me.
Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

Yellow new foliageFrom my research it could be phosphorus toxicity, iron deficiency or sulfur deficiency.
Or it could be over watering.
Or it could be poor drainage.
Or it could be light deficiency (I have a 42watt Tled with some led strips until Mars 600 arrives)

What could have caused this to happen?
Leaves are bending and middle pice of the leaves start to have a little yellowish tint (very lightly) if I can see it correctly.
Overwatered or a nute-deficiency?

Nute Burn? Or something else?I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciated
