Light burn ?

[Just done]

Hey guys. You see top leaves are a bit yellow green. Is it light burn ?

No.. That is not light burn.. What you are seeing are multiple issues due to a nutrient imbalance/lockout.

Yes nutes lockout might be a thing. Last 5 days had to water with no run off ( don’t ask why) what will be bad ? What should I do ?

What will be wrong cuz of nutelock ? What should I do to make things best I can now ?

I read somewhere I should flush it ? I grow in coco by the way.

Unfortunately, it's not that simple... You would need a ppm/ec meter to properly flush and know when to stop flushing.. You need a ppm/ec meter whenever you are using a nutrient line.. That's what tells you how strong your feed or mix is.. Your plant is in flower, so it will not make any new leaves... (That's what veg is).. You can only try to stop/slow the spread. Before any recommendation can be given, we'd need all of your detailed grow info.. Your nutrient line, how/when you feed.. The ph of your feeds.. The ph of run off.. All the basics..

I grow in coco+perlite. I use these nutes ( put picture) I put picture of feed to ) I feed every day. How to slow it ? Should I stop nutrients at all ? ( feed is when started to flower this page )

Run off every day 10-15% of what goes in. Add nutes at equal and balanced strength.
At a minimum you need a PH pen. Ec meter helps you monitor the actual strength of input fertigation so you are not over or under feeding.

I have ph pen. Always putting in 5.9-6.2 (ph pen is accurate ) put in same nutes? Don’t cut it ?

Let's say manufacturer says 5ml of base, their recommendations are usually too strong, and you put in 2.5ml or 50%. Then the next one says 1ml per litre you administer that at 0.5ml or 50% too and again with the next one till they have all been added at 50%. Check ec against where you want to be and adjust as necessary. I figured out how many ec, @ 1ml per litre, every nute bottle added to my tap water, then mixed it a bit higher than my target then water down and ph at the end.
