I have 5 White Widow seedling started on 9/22, and planted into the solo cups on 9/23. The first three broke ground on 9/25 with the last two a few days later (might not run those ones). Phenos # 1 & 2 look great, 4&5 are slow growers, but what is up with #3? She come out of the coco and unfurled what looks like nute burned leaves. They are in raw coco and perlite. All of them have been getting sensi grow a&b at 1 ml per letter. Feeding twice a day with runoff. None of the other plants are showing any issues. They are sitting under a 4 bulb T-5's light. I have only had 2 of the bulbs on for the last week. 18-6 light cycle.

What do you guys think?

It's possible, I hadn't thought of that. I do water with a 100ml syringe attached to a tube. I usually water the perimeter, but something may have gotten on there. Thanks.

Also, when do you guys think would be a good time to put them under a 400w MH light?

if you have a adjustable ballast,drop to 50% and put them in,,thats how i do it,when they get a full set of leaves bring it up to 75%,after they get 2 knodes ,full power

Thanks. I have the ability to dim down to 250w, and "overcharge" above 400w, whatever wattage that is.

Yeah, my last run I tried to walk that line between optimum height and burning my plants. Measured daily, used the "hand" test, and even bought a Lux meter to find the sweet spot. Ended up with miniatureized new growth and a whole run full of problems. Not this time. That light is staying at least 2 feet above the plants.

tie a string off hanging from light,put a washer on end,when you find the sweet spot,all you got to do is keep the washer on the canopy,easy,in flower the first 2 weeks stretch and after that ,your not moving it no more

Great advice! I did have the probe for my hygrometer attached to the light and hanging at exactly 18". This is what I ended up with. There is a lot going on here, but it started with miniaturized new growth from the light being too close.

think you might have a bit to much nitrogen going in other than that white hairs looking good,that claw and dark dark green leaves is to much nitrogen,back off on it and boast up your p and k,in flower there hogs for it

These were from my last run. I got 3oz of hay. Well, at least that's what it smelled like. Smoked smooth though. High was meh. Here's what I think happened. Light too close causing miniature growth and heat stress. I was also in a blended soil-less coco mix, with its own nutes, and watered it like raw coco. With an ec that was high, even though I had cut the manufacturer recommendation in half. End result was nitrogen toxicity. Learned a lot though.
