Hi guys, my plant is locked, I think it's a nute burn, how can I restart the plant flowering? I also have the Flawless Finish product of Advanced Nutrients, can I use it to flush and restore back the flowering?

Biological Cal/Mag alternative? It appears the cal/mag from BAC is mineral feeding, is that correct?
Starting to see what looks like a deficiency of Cal/Mag. I'm trying completely biological and I can see the Cal/Mag under the mineral nutrients tab from B.A.C. Is there a biological alternative?

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!
10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

The yellowing on the edges of the leaves, is it nutrient burn? I'm at my normal ppms for this stage and never really had this happen but have added fulvic acid to my line up and is supposed to increase nutrient uptake. Any takers?

What is this deficiency?
Some leaves are burnt but the ph is good, watering is good light and temp good soil seems good and balanced. The humidity is very low can it be because of humidity?

What deficiency this is ?
Perhaps in these pictures you can see better, what deficiency this is, whether it is phosphorus, potassium, magnesium or zinc?.

Burnt edges fan leaves
Need some advice please. I added organic dry bloom nutes to a 7 gallon pot a week ago. Since then, a lot of the fan leaves have turned yellow and brown. I have picked a lot off but more come everyday. The question is what can I do now?

Nutrient deficiency which kind and/or light burn?
Do I have some nutrient deficiency or light burn or maybe both? Looks like maybe P or K? I changed my light to a HPS and the plants grew much closer to the light so could be too much PAR/heat so I raised the light. I also had started to add Cal-Mag to my feed just before.

Is this sign of over feeding?
Few of my babies in vegetative stage are encountering this problem. Some of the leaves are showing like those in photo. My guess is overfeeding the nutrients. But before I making any decision, I want to hear some professional opinions. Nutrient feed interval is per 4 days.

Dangerous problems after two weeks of cultivation
1~In the second week, I used 50g of chicken manure, and the nutrient solution used only half of the recommended amount. What effect will this have? 2~I was just exposed to the sun for 12 hours. Can the leaves be resurrected thank you all

Am I starving and dehydrating my plant, or cooking it with nutes and drowning it?
I was thinking the brown spots were nute burn so I've only been moistening the clay medium and little bit of starter soil with 6.5pH water. Of course the roots don't reach the dwc yet. Is my mistake in using no nutes? Is this plant under-nourished and thirsty?
