Hi, the bottom leaves have gone yellow on some of them and they have little white spots on the bigger leafs, I have detected whiteflies and assuming that this is caused by them but can anyone confirm this for me or is there another problem I don't know about?? Thanks guys!

Hey, hey if you’ve id’d white flies then I’d start with neem oil as the general “fix-all”. Or if you’ve sourced another foliar spray then perfect - apply and see what happens. Based on your feeding sched. The yellowing prob. Isn’t nute burn. If you’re referring to the cotelydons then they may simply be dying off. I wouldn’t worry too much about this until/if it starts to translate to the actual leaves. I’ve seen it before myself but not until somewhat later. No need to worry just yet though - monitor and see how it goes. 👊👍 good luck dude!

Hi @ghendrix! Yellowing is usually a sign of a nitrogen deficiency, it means that either your soil is poor, either your current pH does not allow Nitrogen absorption. You should apply a pH range around 6.0~6.2, not above, not below. Now about whileflies, I've experienced very good results using neem-oil. Mix 10~12 drops of pure neem-oil in a liter of water, spray at night when the sun is down, or in the morning before the heat (spray everywhere, onto and below the leaves). Hope this helps, keep us up-to-date and happy growing 👊

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

Root rot? How to fix mid flowerWhat is this and how do I fix it! I am mid flower, plant is not drinking as much as usual, there are several "bleached" spots that I haven't been able to account for-- my guess is root rot despite plant otherwise seeming ok.
How do I fix this midflower with home items?

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?

Leaf mutations in Northern Light Automatic (RQS)Hello. Could this leaf mutation in Northern Light Automatic (RQS) be dangerous to the plants? What could it be caused by? Could this be caused by too much light for the sprout and the Top Crop Green Explosion fertiliser? The leaves grew very strong in a few days after fusion.
