Why are the tips of my leaves brown and yellow

Hi this is my first ever grow and the tips of my leaves are slightly yellow and brown and I don’t know what it is and what to do I think it because of light bleaching or light burn but I want some one with more experience to fact check me on that.

@RASTAMAN1 Hello, friend, it’s definitely not because of the light. I understand you have hydroponics. the problem of nutrition. In hydroponics, the plant is very sensitive to nutrition. Even expanded clay in which the plant can create problems. Here you need to study everything very well

@RASTAMAN1 What kind of water you have and what kind of nutritional composition you have. What you feed. I must say that for hydroponics ph 6,6 is a lot.

I have experience growing on hydroponics. But I came to this after five years of growing on the ground. On hydroponics, the conditions should be perfect

At this stage, I think your PPMs should be higher @ around 400+. LIghting issues usually occur where the plant is receiving the most light. And @Sedrik777 is right, your PH is at the top of acceptable range for hydro.

Just my opinion of course. Good luck.

I agree with you, someone has water from the tap flowing 200 ppm. But this does not mean that it is possible to grow a plant on it. Here is a table of the application of mineral fertilizers. I fully trust these guys, there is feedback from them and everything is growing well.green-house-seed-co-green-house-feeding-long-flowering-1830607224873_x70044

@RASTAMAN1 On hydroponics in use, it is very important to have good water. I have such happiness, my water is very soft. Those who do not have good water use reverse osmosis. You need to know what you feed the plant, this is very important in hydroponics.

Thank you so much for the feedback I have brought back the PH back to a 6.0 and I use water from my RO water system and for the nutrients I just use the general hydroponics flora series

You should have nutrition instructions for your fertilizer. Observe it and everything should be fine. Based on your log 196 ppm is not enough. The plant is starving

@RASTAMAN1 Here is this table that I sent earlier. This table is created specifically for cannabis, powered by mineral fertilizers . It was created by the guys from the company Green-House-Seeds. These guys have been breeding new varieties for many years and they have a fertilizer line. If you use mineral fertilizers, your nutrition parameters should not be different. And don’t experiment with light, it’s not about light, that’s for sure.
