Are you talking about the first picture or second one?

What are you feeding? Looks like needs fed and some Cal Mag. I use Cal Mag through the whole grow.

Perfect pH micro grow bloom, I have ordered some cal mag though just waiting on it to be shipped.

How close is your light? What kind of light are you using? Spill any nutes on the leaves?
Welcome to the community.


It’s about foot an half away, it’s a 600 watt light. No I haven’t spilled any on it that Im aware of. Thank you! Glad I found this forum!


600 watts is bright sure but there is alot more to a light then the watts. LED or otherwise. 18 inches is close for some lights, not for others. Can you give the specs. Actually you should fill out this support ticket, it will help the pros around here get a bead on any problems they see with your method.

Always try to upload a clear picture in white light of any issues you may have to allow the community to identify your issue.

Anything you feel would help us give you more informed advice should be included. Feel free to elaborate at the end of the survey.

I also recomend starting a grow journal. Its helpful to have a singular place you can go back to to keep track of the tips given and progression made. If you are reading other threads and want to ask a question of the grower who has caught your eye tag them in your journal with your question by putting am @ symbol in front of their handle. Like so… @Docnraq what plants are you growing? I recomend looking into the journals by @Covertgrower @Budz @Nicky @PurpNGold74 and @MidwestGuy and @Hellraiser they are some of the most knowledgeable on the boards here. In truth you kinda can’t help but hit a pro around here if you throw a stick in the air. If you got a question feel free to tag me and I’ll help if I can or ill point you to someone who can. Happy growing, you are in the right place.


Thanks for the tag Doc! Welcome to the forum @Creamcheese

Normally light bleaching is first seen at the points of plant closest to the lights. That looks lower and in the plant.

The last pic (full yellow leaf) looks more like the plant is a bit hungry. Id love to see pH and ppm numbers for said plant. Would tell a story of its own.

The first pic looks a bit like the color u expect from bleaching, but as stated above, that lime loud green is normal for some plants. Another picture with a bit better focus/lighting would help there.

Happy growing and keep us informed


I will get you guys some numbers on pH an all as soon as I can and a better picture.
