deficiency or pest, grow halted.

Thanks all for the help, I do think it’s light stress coupled with some pest. I raised the light a few days ago as far as possible on the tent, it looks like the light burn is still getting worse though.. I also fed the other day so tommorow I can check ph lvls. I don’t have a ec meter though so I am sol there. I have a feeling I’m low on bloom nutes and the plants telling me, as I have just been on ff trio. I got some bud candy from greenlife nutrients on the way for a bloom booster. Bottoms don’t look so great which makes me think there is a pest. Growth is slow non existent. I will leave a pic as soon as I figure out how.

It is easy to mix up nitrogen deficiency with light burn. A major differentiating pattern is that when leaves are deficient in nitrogen, they turn yellow and fall off while leaves with light burn do not wilt and do not fall off unless plucked. Another difference between these two problems is that with nitrogen deficiency, yellowing starts at the bottom of the plant, whereas, with light burn it commonly starts at the top. Initial signs of light burn show up in the leaves that are close to the light or at the top. The leaves may start curling upwards to in order to shade themselves. Leaves lose their luster and become crispy. The leaves may appear burnt with brown spotting. The leaves may not turn yellow, but instead, the tips may be strangely pointing upwards in the beginning. As the problem continues, leaves start to turn yellow. The leaves that are more exposed to the light will be lighter in color in comparison to other leaves. Leaves (and particularly tips of the leaves) turn yellow but upon close inspection, you will notice that the veins stay green.

Check your runoff waters ph and economic levels. When diagnosis is needed, this is how to do it. Make sure ph is proper, or you have some lockout. Make sure your ec isn't to high, if it is its also lockout. If your ec is low, then you have deficiency happening. Cheers
