Slow growth yellow leaf edges what to do?
Plant growing slowly (but still growing) with weak growth tips and yellow edges on leaves with interveinal chlorosis. Looks like overwatering / magnesium deficiency to me. I use a weighing scale to know when to water, but started the plant in 25L pot so this might have caused it.

Anyone know what's wrong with my girl?
Can anyone tell me if this is going to effect my flowers? Should I cut these leaves out? What can I do to correct it? I left a pretty good description in week 7 of the battle with this plant.

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?
I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

Is this light burn?
All my leaf tips are going yellow, even on the bud leaves. It does seem to be a bit worse towards the top of the plant. Is this light burn? I am using 2x 1000w philzon LEDs in a 3.5'x3.5' Tent and I had them at 10/10 brightness. I just reduced to 8/10. Thanks in advance

best leaf insects repellent
I have found a few bad insects on my plants past weeks. Does anyone have experience with neem oil? Is it worth a try or would I be better of buying something else? White vinegar with dishsoap didn't help much. The bugs are: grasshoppers, stinkbugs, spidermites & fungus gnats.
