Leaves problem
PinkParrotstarted grow question 4y 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 at bottom. New growth good. How she looking?Tried a new nutrient line, instant Pythian(sp?). Switched back now and she seems better. Should I be concerned at this point? New growth looks good to me. Although she seems droopy for this time of day.
My theory is that the new line was more sensitive to warmer water temps.

What nutrient deficiency is this?What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Yellow leaves question.Good morning growers,
I have noticed some yellowing of the bottom flowers on my one of my plants. Everything else looks extremely vibrant and healthy. Does this look like a watering or nutrient issue? Or is it something I should not be too concerned with ? Thank you everyone :)Week 3

Organic grow, yellow leaves, autoflowerFirst ever grow. I'm in my 5th week of autoflower, organic grow. Using the bomb paonia soil, raging kush light and boogie brew tea and filter to water. Temps are steady around 86. Started noticing yellowing on bottom leaves. I'm pretty sure it's from under watering? any feedback?

Is this light burn?All my leaf tips are going yellow, even on the bud leaves. It does seem to be a bit worse towards the top of the plant. Is this light burn? I am using 2x 1000w philzon LEDs in a 3.5'x3.5' Tent and I had them at 10/10 brightness. I just reduced to 8/10. Thanks in advance

Yellow Leaves with necrosisHi,
My weed have some troubles, i can see some leaves becoming yellow with some "yellow points" ..
At the end of the leaves, it is, i guess, some necrosis and it's curling down.
Could you help me please ? I think it's a calcium deficiency but not sure.
