Yellow veins
AcidFarmerstarted grow question 4 years ago
Hello growers, my girls have these yellow veins on the leaves, could it be a slightly too low pH and the consequent deficiency of magnesium? How can I act? Can some Epsom salt help? Thanks

epsom salt with the right ph would help, if you're using synthetic nutes give her cal mag with right ph flush

Looks like a iron deficiency to me, I had a similar issue on my Week 3 of Veg in my diary if you'd like to compare pics. Had it on the Sunset Sherbet and the Tangie. I fixed this with a foliar feed of chelated iron while I got my PH in check. The foliar feed showed results in about a day, but not a permanent fix until you fix the PH. Once the PH issue was resolved, the need for a iron foliar feed was no longer needed.

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Slight Leaf Discoloration. Early zinc deficiency?Girl showing slight discoloration on newer leaves. Mostly interveinal + little on the tips. Guessing it's an early zinc def. but would like another opinion. Watering sparingly at ph 6.3 - 6.5. No runoff yet, so ph may be higher in soil. Lower ph and watering til runoff next time?

Yellowing between veins on 3 of 4 plants, and curled tips - 27-29C in tent - Just heat/light stress or something more?Only on 3 out of 4 of my girls, see 1 pic of sad girl and 1 pic of happy girl. Does it look like heat/light stress to you or something more?
I was running my LED 45 cm below the lights dimmed to provide 20-30k lux at plant level. Just now raised to 65cm, lux 20k.

Leave color normal?? [First timer]I am not sure about the color of the leaves if they look normal? The baby leaf seems to be turning a bit yellow. The rest of the leaves seem to be a bit discolored as you can see in the pictures but mainly green though. Is this alright or am I doing something wrong here?

intervenal discoloration, organic growGave her enzimes last week, maybe they were too much or some nutrient lock out due to a somewhat excessive fertilization (too much vermicompost)
Think I will go on with plain water to the end I think maybe the problem will sort out itself or wont degenerate too much. Any advice?3 years ago

Roots getting brownMy Ph probe didn't work, PH was at least more than 0.30 (maybe 0.60) than displayed. As a result they had multiple chlorosis, now septoria leaf spots and possible Pythium since the roots are getting brown. What would you do to save the crop ? Adding mycorrhizae? Thx!

我的女孩怎麼了，這個是生病了嗎？還是太多的餵食？在他長出第二對葉子的時候這樣的現象就出現了，但是只有一邊有葉子，我查了相關資料顯示這是菸草鑲嵌病毒（Tobacco mosaic virus；TMV）
我覺得挺像的。但是不是很確定，我該繼續等幾天嗎？還是把葉子切掉。
誰可以告訴我解決方法，希望他可以度過生長期，因為他是自動開花，每一天都很重要。
