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!

Cut off yellow leaves.Can I cut off these leaves?
I am worried that this is an autoflowering plant and it will be an additional stress for it. But it also seems to me that it is spending some effort to keep these leaves alive and it would be better if it spent this effort on the buds.

Super soil growers ever come across any deficiencies? See a couple lower fan leaves I removed today. I'm sure leaf loss to some extent is natural, but I read that the lower leaves are your indicators, so I wanted to run these by yall to see if you suspect and deficienciesWeek 8

Small, flowersHello guys,
This is my first autoflower grow. Flowering started 8 weeks ago as of today.
My plants don’t look too good — it seems like the buds aren’t developing properly, and I think there is a strong nutrient deficiency as well.
What could I have done wrong?

What is this deficiency?They started off with some brown spots and progressed. Is this phosphorus? I have been feeding with .5-1ml of dyna grow bloom and 2ml of cal mag per gallon watering at about 6.3-4 ph. But i recalibrated my ph pen and did one water since.

What is happening? Leavescan someone please help me, what am i doing wrong?
My guess is to much nutrients or oversalting - Nut lockout?
it could also be, I have been watering them every day with fertilizer mix, without a day of water in between, but I always fertilize less than specified - Plagron

Ph issue?Hello, I'm getting a bit worried. I'm not sure does this yellowing happen because of my high ph? I think my soil have been moistured pretty long and wouldn't want to try lower their ph with water. Have anyone ideas what is the problem and how could I fix it? Thank you in advance!

Yellowing leaves.Accidentally resolved my original question instead of liking a suggestion and I cant change it 😅
Same issue still applies for now.
I have been testing the PH going in but not out so I will try this and pass on my results after the next water 👍
