Leaves problem
PinkParrotstarted grow question 2 years ago
We start a hydroponic culture (ebb & flow) at the end of the 3rd week of vegetation and we see spots appear on our leaves.
We are testing two types of hydro A&B dosages from Plagron. Left tanks PH 6 EC 1.1 and right tanks PH 5.9 EC 1.4.
Thank you in advance for your feedback!

You are suffering nutrition burn. Brown curled in tips is nutrition burn. If they were straight I would say potassium deficiency. I imagine your ph is dropping as well. Your ec needs to come down. Vegging npk ratio is 3-1-2 for nutrition.

Your EC is much too high for this age plant.... should be down between 0.6 and 0.8... pH is fine but get that EC down! You're developing a lot of toxicity...
Good luck!

Yellow leaves, red discoloration on couple of branches1st plant-day 37
2nd plant-day 36
In both cases, the first leaves turn yellow at the very bottom. They are to be cut after 60 days. On two plants, red discoloration appear on some branches. Both are higher than in the manufacturer's description. Is everything ok so far?

Yellow lower leavesHi! I went out for the weekend and when i came back most of my plants had yellow lower leaves. The weekend has been very very hot and im wondering if it was lack of watering or is it a lack of nitrogen? Some in one plant the leaves were dead.

Is this nitrogen deficiency or something else?Hello everyone!
One of my plants has some fan leaves and new leaves yellowing at the bottom (and some are crispy). The plant is very bushy but from what I understand this could be nitrogen deficiency but wanted to check. The other plant is smaller and doesn't have yellow leaves

Leaf DiagnosisCould someone help diagnose this leaf problem. It's less than 2 days old. Aañnnnnd, 2 days ago I accidentally set the ppm to 1700? I've since dumped the solution and got it back down to around 700 ppm. I'm hoping someone give me some triage pointers. Should I trim those leaves?
