Strange growing plant

[Wildkidz420]

looking for a litttle help with my plant. Its a 5-alive sativa grown in destiny super soil. Fed fish fertilizer 5-1-1, and realgrowers recharge alternating between waterings. Kept in a greenhouse. The newer growth I'm getting is deformed and leaves are yellowing up the center. Some leaves have a yellowing leopard print on them. In general the plant looks very healthy. The plants were up potted about a week ago from 3 gal to 7 gal. I dont PH my water, but let the tap water sit for at least 24 hours to dechlorinate. Thanks in advance for your help. Happy growing.

If I were you I'd hit up @Emilya pretty quick before things get bad. She knows this super soil stuff really well & I'm sure she'll know exactly what it is & how to fix it.

Thank you, will do.

That looks like light damage... have you measured your LUX at the top of the canopy?

No. I will have to check that out. I will have to pickup a meter. Would light issues be strain dependent? My other plants are showing no signs of this? Also this issue seems to be central to only new growth sites, would something like that not be all over the plant or because the new growth is so tender it is affected first? I see I can attach photos, so I will. Thanks again so much for your help.

yes, some strains can tolerate more light than others. It is always difficult when having multiple strains in the same grow room. Get a $35 or so meter at the online stores and it will be a few steps better than a cell phone app and will give you a good idea the LUX you are throwing out. The closer to white spectrum you are at, the more accurate the reading will be. Then compare your readings with this chart that I compiled to check out my new COB light array and you will see the levels of LUX for each stage of growth.

I'm growing outside in a greenhouse, does the same apply?

yes, it could definitely be possible to be giving the young plants too much... but that begs the question: how hot is it out there?

The plant was planted in the middle of February and has grown up inside under a LED veg light. They have been outside for approximately 3 weeks and daytime temperatures are around the 16-25° this time of year. I have a oscillating fan on them and the highest I have seen the inside greenhouse temperature is 33°

Yeah... lets see what a light meter says... the damage looks physical to me, not nutritional.

Okay, I will get a meter ordered today and have a look. I will report back, if you don't mind in a few days. Thanks again.
